Saab 9-5 DIY: Vacuum Line Replacement (Silicone Hoses) - Trionic Seven
Vložit
- čas přidán 17. 08. 2015
- This is a detailed guide for replacing the vacuum lines in your Saab 9-5. Instructions should also apply to the Saab 900, Saab 9000 and Saab 9-3, however there might be some minor differences. The old lines are made of rubber which will become brittle with age and eventually break. I choose to use high-quality silicone hoses for the new lines. Silicone is age-resistant and will last the lifetime of the car. Also, I like the color of the blue hoses, however you can buy them in any color depending on your preferences.
I highly recommend replacing the vacuum lines in your Saab. Silicone hoses are cheap, too, and can be found in almost any car parts store (just avoid the very cheapest stuff). Time required is roughly 30 minutes to one hour. It can fix problems such as whistling noise, boost leak, vacuum leak and low performance.
You will need approx. 3 meters (10 ft) of hose with an inner diameter of 4mm. The outer diameter isn't important, but the hose in this video has an outer diameter of 8mm.
Tools needed: Knife and side cutters. You can also add cable ties over the nipples to make extra sure that the hoses do not let go, however I didn't do this here. In addition, you can replace the check valve line that goes to the PCV system. If you have still have problems with boost leaks you can check the EVAP line mentioned in the end of the video.
If you need more access to the lines close to the firewall you can move the main harness connector away, check my video on replacing the coolant bypass valve for instructions: • Saab 9-5 DIY: Coolant ... .
Since I found a loose hose I was quickly able to diagnose and fix my boost leak problems. Now the Saab 9-5 Aero boosts up to 1.1 bars again, a significant improvement.
In Swedish: Denna film visar hur man byter vakuumslangar i en Saab 9-5, 900, 9000 eller 9-3. Om turbon inte laddar fullt bör du börja med att titta över slangarna, i mitt fall hade jag en slang som lossnat. Gummi åldras och med tiden blir slangarna väldigt sköra och torra, och därför är det bättre att använda sillikon till de nya slangarna. Du behöver cirka 3 meter slang med 4mm innerdiameter. Köp inte slang från Biltema eftersom många har haft problem med denna.

Thanks for the video. I was about to go online to buy a new bypass valve but after seeing your video I knew what to look for under the bonnet. Found the disconnected hose, cleared the engine warning light, job done. Cheers, Pete
Awesome! It's the best feeling to know that my videos helped someone.
This video was insanely helpful. I had the same problem with the second hose not being attached to anything.
Thanks for this, I replaced my vacuum lines for silicone with this video and solved the minor boost leak it had 👌 subscribed
Thanks so much for this video! I had the exact same boost leak. Now my aero really takes off!
Awesome video! Very helpful, thank you for taking the time to make it!
Just a note to let you know that your video is still helping people in October 2018. I had the head gasket replaced in my 2005 Saab 9-5 and after the work was done, my car would not idle correctly so I decided to try replacing the vacuum lines in the hope that would help. I followed your video exactly and found a cracked line which fixed the problem. Your directions were superb and each step was easily described and well documented. Thanks for the great guide to this repair!!!
Awesome, that's what this channel is for :)
Holy crap! Big difference! The car builds boost so much better now.
Some notes after just completing:
1: The outside diameter is important for one hose: the brake booster. There's a plastic ring around it, and my 10mm out diameters hoses were too big. Stick to 8.
2: You don't need to remove the entire wiring harness, but undoing the two bolts holding it in place so you can jiggle it up and down makes a huge difference.
3: Be prepared to have someone help you. All of my hoses broke off on the nipple. It would have my life easier if someone held the part up for me while I cut it off.
This is great. My next job for the weekend. Really enjoying your channel - bought a 2006 Vector Sport 2.3t recently and gradually working through the little maintenance jobs like these.
Go for it, it's a perfect weekend job :)
Thank you for this guide, did this today and it was needed
+Mikael Arvidsson Glad to help!
Small point for clarity - at 6:05, if you have NOT removed the junction box assembly from the rear bulkhead, it is not completely obvious that the hose from the TOP of the double manifold connector goes to the solenoid valve, at the opposite end to the longest hose, and next to the electrical connector. With the box in place, this is hidden under it and so a bit hard to get to - but not impossible. (Mine had come adrift - this video helped me find where the loose end came from - thanks T7!)
Thank you for att nice video. Of course I signed up immediately when I found you.
I recently bought a broken and partially disassembled 9-3 aero -02. I was a Saab mechanic in the 19th. But things have happened since then :).
Btw, it's a proven fact that Saab people are better people than others. Everybody knows that ;)
Thanks :) Haha :D
Thanks for the guide! Did on my 2006 9-5 auto this week and this was very helpful. One comment, the plastic tee was very brittle on mind and as broke it. It might be useful to have a replacement tee handy.
Thank you so much for this video. You helped me locate a detached vacuum line and one that was in the wrong plave.
Excellent video, slightly different on my 2004 2.3T (220hp), no T connector so only 4 hoses. Found the turbo pipe very stiff so could not pull off the throttle body, however removing the brake vacuum pipe was sufficient for me to get new silicone line in place. Turbo gauge now shows more stable boost pressure, thanks!
Yep, different model years are slightly different. Glad it solved your issues :)
I have done this to my car and im happy with the results. There are however some really annoying and tight spaces that you´ll hate but when youre done its all good : )
Yep, vacuum lines can make an awesome difference on slightly older cars. Glad you felt the difference! :)
Thank you soooo much man, super helpful video, made my life 10x easier! 👍👍
Underhållande, jag har också problem med luftläcka, och exakt samma slang som var av för dig var av för mig också! Tack för 'tipset'! :)
+bjorn47 Kul att det hjälpte!
Great video and very informative, helped me a lot
Thanks for this video. I have the same hose taken off. Is the bit, that the first hose supposed to be connected to also needs changing, or at least check for blockage? Also: is the turbo long hose the same diameter? My one looks a bit thicker, than the rest (2004 Aero)?
Thankyou yet again for another video! Much appreciated.Vacuum hoses ! The source of so many problems !
My 2001 VW T4 had been playing up for a couple of years before I finally realized it was just a question of perished vacuum hoses. At the same time my 1999 9-5 started presenting the same symptoms, so I replaced all the hoses with silicone ones. Problem solved again!!
I’m going to order some silicone hose right now and replace all of these on my « new » 2004 Aero wagon. Thanks for reminding me 👍
I do still have a « loose » hose which comes from the front of the engine compartment, I just can’t see what it should be connected to. I had the same on my 1999 2.0t. Any ideas?
Cool Video Thanks!
Awesome!
Superbly detailed video, I just got my silicone hose through today so this will be my first vacuum line replacement on my 04 Saab 9-5 Aero, one question though, are hose clamps or ties needed for the ends at all?
+Malcolm Cooper Some say they are needed, some say they're not. If you want to be safe, put them on! :D
+Trionic at 3:20 in the video you are changing and re-attaching the hose from the throttle body to the black box on the back firewall, my04 9-5 aero has a slightly different setup to yours, mine has the throttle body pipe blocked with a screw (expect some kind of bolt mod by a previous owner) and the firewall has no pipe going in and also a dangling connector which I have no idea where it came from. does this hose have any impact on performance when re-attached?
Trionic Seven trying to figure out where the small black hose at 4:23 attaches to on the opposite end from intake manifold fitting...I have a 2001 9-5 Aero..Thank you.
Did this today. Your video was extremely helpful! THX! The tube you have coming out of the brake booster is missing from my 01' 9-5. That entire mechanism, the two pipes and the diaphragm they connect to. Is that a mod someone did or just different on the 01'?
Your pipe is probably missing because you have an automatic gearbox.
Could vacuum leak be also responsible for turbo overboost? Mine should be 0,8 bar but sometimes it goes up to 1,1-1,2 bar.
Tack så mycket!
Great video as usual! Though I would like to ask when should I replace my vaccum lines? and what are they actually used for?
Man Oat Thanks! There is no set interval for replacing the lines, so unless you have problems it will never get done during regular service. Vacuum lines are used for many "little" things in the engine, such as remote control of valves, vacuum transport, vapour transfer. When they go bad, many "little" problems can occur, but nothing really serious.
Are the vacuum lines fairly the same on the linear model? Just ordered new vacuum lines for mine.
thank you thank you thank you. I have the Saab WIS but it was not helpful at all on this- this was great.
Stort tack för den här videon, har en 04:a där motorn känts orolig och inte levererat effekt på samma sätt som tidigare. Efter byte av vakuumslangarna så känns den i princip som ny igen!
Vakuumslangar gör stor skillnad. Kul att det blev bättre :)
What is that red insert adapter called ? Where the hose gets inserted to ? My mechanic says I need that part ? Thanks.
Great stuff as usual! I just replaced the first two and there were clear holes in the hoses I removed. Two questions, however, is it okay to use inner diameter of 3.5mm? Also, regarding the one that goes down below from the T-connection (the one that has the check valve). Looking down from the top with a flashlight, when I wiggle the hose I can see the check valve down there, but where the hose below that check valve connects would appear to be some assembly that is just loose - maybe some type of bracket. In other words, I wiggle the hose, and while I cannot see the absolute bottom end connection, I see some little assembly loose and wiggling as well. Do you know what this is?
I know that the hose I used was 4mm, don't know if anything else will fit. Unfortunately I don't know the answer to your other question but I suggest you ask on one of many Saab forums :)
Do you know were to find the door lock relay for saab 9-5 2005 plzz
Jag har inte vakuumslangen till broms-servot (den du visar hur man tar ur insuget). Är den ett måste? Den existerade inte när jag köpte bilen. 2,3t -03
Hi- On the thermostate are 2 13mm bolts and 2 10mm bolts.-on one 10mm bolt goes a ground wire - what goes on the other 10mm bolt??
Thank you
Ingo Broeg
Hej.
Jag har precis bytt vakumslangar på bilen.
Men jag har inte den tkopplingen som du hade på den sista slangen. Bör det vara det, kanske tidigsre ägare som felkopplat.
Saab 9-5 2,3t 04.
I have a problem doing the last one... i must do it!
3:51 next to the brake power hose theres a another hard plastic line, what is it? i have one of a kind model in mine and i need to replace it but i cant find any parts like it. I dont think its original
Great video. I feel like it would easier to run the new hose along the old . before removing the old. So you know it's run the same way.
Good tip
Learned from replacing dirtbike wires. Things that move pull on things. So you want to run the same way it came.
I bought the silicone hoses to do this though. Like the colored idea.
Where did u order them silicone hoses from? I'm looking in Amazon and nothing..it doesn't match up the 4 mm inner and 8mm diameter outer?? Well I have a 2006 Saab 9-5 and it uses 3/16.I recently purchased hose from advanced auto and the size for my 2006 Saab 9-5 was for that size due to not waiting for Amazon order.Silicone hose is superior to rubber hose for longer life and flexibility..Also it looks really nice.Great way to sell ur car when they pop the hood.
Tip: Something I notice today when I did change my vacuum hoses. Is that if you have removed the bypass valve to for the cooling fluid. You will missing the T-connection. I did scratch my head for a while before I did see that some previous owner have removed it.
***** Could this be the BCV bypass mod? Several people have done this, however I am skeptical for the time being. www.saab-tuners.com/trionic-7-turbo-stable-throttle-response-mod?___store=english&___from_store=nederlands
Trionic Seven: For Saab Enthusiasts No. The Crane on the firewall or what you call it to the coolant. That thing have been removed for me so that's why I don't have a T-Connection on one of the hoses. So all hoses are connected just missing the T-Connection. And that BCV Bypass mod is something I have thinking about trying out.
@@TrionicSeven That link is now dead, but thanks to the Wayback Machine I was able to find it. I'm adding the text from the page here for future reference.
TRIONIC 7 TURBO STABLE THROTTLE RESPONSE MODIFICATION
If you have ever refitted your 4mm vacuum hoses for silicone hoses (a must do in my opinion), you will have noticed a little black box with three hoses connected to it. Have you ever wondered what that box does? I sure have.
The box works as a control for the turbo bypass valve, when the box is disconnected the turbo bypass valve is "hooting" a little under light throttle. This is kept under control by this valve, reducing the noise under the hood. When you bypass this valve you will get a more responsive throttle feel.
In simple words: when you do this modification you will be able to take speed bumps in second gear on a manual gearbox Saab without the car hickupping and struggling. It will go smooth, even under idle rpm.
What you need to do is the following.
Disconnect the vacuum line from the throttle body and cap the throttle body vacuum exit with a silicone cap.
You can also (temperarily) do this by cutting 35 mm of vacuum line, plug it with a screw and make it durable with a hose clamp (see image).
Disconnect the top one of the two hoses running to the manifold connection op top of the inlet manifold on the right of the throttle body.
Connect the bypass valve (/ recirculating dump valve) directly to the top manifold connection on the inlet manifold you just disconnected. If your Saab has a T-splitter somewhere in the lines (9-5 only) you are replacing you can add the T-splitter in the new line between the manifold and the bypass valve.
Remove all the excess vacuum lines connected to the valve on the firewall but leave it electrically plugged in otherwise you will get a CE light.
All done, reset your ECU by unplugging the battery for 30 minutes or pull the ECU fuse for a minute to get a fresh start. This is however not absolutely neceserry, on a manual gearbox Saab you will immediately feel te difference.
After replacing the lines how did you initiate a system reset for the computer to reconfigure the boost pressure?
+Evan Merrick No need, the system adapts itself.
Hi, just to make it clear are all hoses same diameter size?
Jag saknar T-korset och den där backventilen (tror jag det är) som går från den överta slangen från vakuumstationen, jag har bara en lös slang som hänger där. är det farligt och köra så? kan motorn skadas på något sätt?
+Sjonnie ks Det finns en del variationer mellan årsmodellerna, men om du har en lös slang är något fel. Jag skulle rekommendera att du går och frågar på närmaste forum för att se om någon känner igen det. Jag vet bara hur det ser ut på min bil. Lycka till! :)
Bytte nästan alla slangar du pekade på i min 9-3, kunde dock inte hitta slangarna från 5:30 och framåt. Är det något specifikt för 9-5, eller någon särskild trimnivå som jag kanske saknar?
+Thord Johansson Det skiljer ganska mycket på olika årsmodeller av 9-5, så jag kan tänka mig att det skiljer ännu mer till en 9-3. Byt bara en slang i taget så borde det funka bra!
Your Welcome :) Det var så lite så.
Erik Axelsson Tack så mycket! Den kom bra till pass!
ska precis göra detta på min saab 9-5 från 99 och jag är inte så bilkunnig så detta var en väldigt bra video :)
Varning: Byta vakuumslangar gör att man blir sugen på att meka, det börjar med vakuumslangar och slutar med att man vill byta turbo, renovera motorn, sätta in bussningar etcetera :P
Trionic Seven hahaha ja det är nog lätt hänt men min bil är en gammal 9-5 från 99 så den är inte allt för fin annars hade jag nog gjort som du sa nu haha
Would the vacuum lines on a 2005 Saab 9-5 2.0t be 4mm too? Rather than 6mm?
I appreciate your video sir. Question if i may, what is the name of the hose that comes out directly behind the “saab”. I have a leak on mine. (2001 saab 9-3)
specifically the leak is where it connects to the engine (behind “saab”). It does not connect properly, thus a leak
I have Saab 2001 9-3 SE that I have owned for about 7 months and lately I have been chasing different problems. I'm wondering if the blue silicone lines you used will also work with my 9-3? BTW, this is a great channel and has helped me a lot so far. I actually have a problem of the car wanting to go upon acceleration but it feels more like it's pulsing and I'm wondering if a vacuum leak could be the cause.
The T7 9-3 is quite similar to the 9-5, but I guess hose routing could be somewhat different. Just change one hose at a time and you'll figure it out. For hesitant acceleration i would check plugs and air filter.
That hose you said it was impossible to show where it goes...with the valve..Mine wasn't connected to anything..and I couldn't find where there is a nipple on the firewall.
Use a mirror and light.
Is it very important that the hoses are exactly the same length as the originals? Or it dosent matter?
Are there different valves build in? I mean that at the firewall with the 3 connectors, beside the hot water valve.
What do you mean by different valves?
the line you talk about going to pcv system where does it connect to thanks
+J Johnson Where in the video?
Omg the check valve one that goes down got disconnected and was who knows where.
So the check valve to the T joint one, it connects below the thermostat bi pass valve, really close to another vacuum line you replaced earlier in the video.
Hope this helps someone else!
On my last 9-5 I used 5/32" (or 3.5MM hose) which seemed about right. Are you using a larger inner diameter hose because its a silicon hose ? Very informative video, but the Dame Edna is a bit different it looks like.
Inner diameter? I think 4mm is the outer diameter.
Sorry for not replying sooner. I measured it, and that is indeed the inner diameter.
what were the symptoms of your boost leak?
Hi,
Thanks again for a great video. Would you mind telling what OBD2 app and adaptor you are using? Also what phone would be helpful. I know there are serious compatible issues with this three.
+Mats Jk If you use a genuing ELM327 you can use any android phone. I recomment Torque Pro.
+Trionic Seven: For Saab Enthusiasts Can you send a link to what ELM327 and what version of Android you have? I have been trying many, and also others have big problems with wifi and bluetooth. Now I have an iPhone, and even if there is a ELM327 for iPhone it still don't work.
I don't really know. If you bought the ELM327 from ebay you might have your problem there. I bought the ELM327 from Kjell & Company in Sweden. I am using Android 5.1, but that is not reallly relevant as it works with all Android versions. What problems do you have?
+Trionic Seven: For Saab Enthusiasts Ok so you have the blue one. I also have it. But with this ODB2 adaptors it seems we also need a little bit of luck to get it working. People (like me) can't get them to pair. Most don't even show up. But I will try with my wife's Samsung (Android) to see if theres any luck.
What error message do you get?
Any idea how to change the Vacuum valve on a 95? The bit showing at 3:32 mine is missing a connector for the hose to go around, but it looks to be riveted in place.
The workshop manual says to drill the rivets out and then use new rivets. Good luck! :)
#Keith & Cars Thank you just been sent here from a viewer of yours i shall do this on mine thank you for the step through tutorial you will be by my side once ordered right stuff
Could you help me with the part number for the 2 valves: red/white and white/white one? And a link for the silicone ?
I don't have EPC on me right now, but EPC is the catalog where you find everything you need. I have a separate video on finding part numbers!
I have a p1110 on my 2008 saab 96 aero
Is it 4 or 6mm around the firewall.
I heard some are 4 and some are 6
Ett tips: låt mer positivare och höj tempot i videon, känns så trist och tråkigt! DOCK informativt.
Absolut! Det är lite klurigt att prata på engelska och då låter det lite segt. Men denna film är nästan ett år gammal och det har hänt saker sedan dess :)
Is it the same arrangement of vacuum hoses and 2.0t 150hp?
There are small difference between each model, but replace one hose at a time and you can't go wrong.
Hi where does the white check valve from the valve cover nipple go to? The one you didn't replace thanks
It goes to throtle body, under blue wire he connected in this video as second, it goes under two black thick runner wires into the throtle body
How are the silicone hoses holding up? They are not oil or fuel resistant, thinking about using them for the EVAP system, so the fuel vapor will deteriorate them
They held up all they way to the junkyard. (The car no longer runs due to an unrelated engine failure)
Hey Johnathan, what brand did you buy for those hoses? Thx in advance.
Speedparts. They worked great :)
+Trionic seven Jag har nu bytt mitt PCV-system och samtidigt mina vakuum-slangar enligt din instruktion. Men det ser inte lika dant ut. Jag har tex inte den slangen Break boster hose i min bil, som du visar 2:05 in i filmen. Jag har samma årsmodel och 9-5 aero TJE057. Jag har ej heller coolant by pass valve och den t-kopplingen du pratar om.
+lars niklasson Kan det vara så att du har automatlåda?
+Jonathan Jogenfors (Jonathan Fors) ja naturligtvis är det så. skönt jag fick veta. tack
great video!
can you do this on you 2006 saab?
Of course! There will be slight differences, but change one hose at a time and you can't go wrong.
great video my question I have is there a way to get a complete vacuum hose diagram I just rebuilt my engine everything is new but the vacuum hoses the guy I got the car from had a birds nest in the compartment and I just cut it away they went to the wrong spots but when I look in my wis . eac and epc I can not find a complete diagram and what I did find only covers a couple items any subjections as to where to look thanks anyone for your help
+robert m Hey! All vacuum hose diagrams can be found in WIS, did you check the "general information" tab?
yes I have looked in that section and found some of the routing of hoses that I needed but there is a tube that comes from my vacuum pump (electric) in the wis that does not show the end where it goes I know it splits to the booster for the brake but I have a nipple on my intake manifold like the one on your tube that is on top of the TB that has the red release ring I'm trying to find where that goes non of my diagrams show where that connects mine is a 1999 9-5 2.3 turbo trying to explain it as best as possible thanks for any help
found all the info thanks
I bought a SAAB recently and found one of these hoses laying loose in the bay and have no clue where it would go. Everything seems to be running properly but it always worried me. Would things run "normally" without one of these?
Edit: Driving a 2003 93 Linear
There are hoses from the automatic gearbox for breathing purposes
hej har en Saab 95 2.3t som bara går på tre cylindrar bytat tändstift och kasset kan det va spridaren eller vet någon något annat det kan va mvh Mathias
+Mathias Liljeblad Kolla bränslepumpen, de brukar gå sönder.
I have a saab 9-5 from 2005 that looks pretty much like yours. About two weeks ago I noticed a sound I never heard before. When I turn my key all the way but don't turn on the engine I hear a clicking noice for about 5 seconds. It seems to come from the little box with all the wires that you can see in your video at 1:55 seconds. Do you know what that box is or does? If you do please reply in swedish the name of whatever that thing is. The reason I ask this is because the same day I noticed this sound my car started to idle really low and sometimes die on me completely. The car also sometimes jerk forwards when I accelerate but that rarely happends.
btw great video. You do great content!
That box is probably just the main connector, not sure of the name in Swedish actually. Is there an electric fault somewhere there?
Jag bytade precis alla sladdar som du gjort på videon, men de pyser fortfarande när turbon går in.. :/. har du någon aning om vad de kan vara? Fler saker man kan byta? tack
Evap-backventilerna! Googla efter "rycka R-slang" så får du veta mer.
Ska testa de imorgon! Kan de vara strul med "backventilen" också?
+Trionic Seven: For Saab Enthusiasts jag bytade tändstift idag och hackandet är helt borta :) även tomgången är helt stabil nu!
Hi I need your help please I replace the turbo charger for 2003 Saab 93 convertible after I replace it the car it doesn’t give me a lot to respond when I drive it I would like to make a video but I don’t know how I can send it to you
En fråga: SAAB 9-5 Griffin V& 1999 , Check Engine lampa lyser och klagar på vacuumläckage. Vad är det för skillnader mot 4 cylindiga motorer?
+SwePianoholic Det är en helt annan motor, rätt lite gemensamt. Däremot kan man ju byta vakuumslangar en i taget, då blir det inte fel. Det kanske löser problemet.
Thank you very much for your tutorial video! I'm going to change them, engine is failing... :(
Dear Trionic Seven i accidentally broke my turbo flange bolt but the other three seemed tight however i have a delay in acceleration do you think that i may be loosing boost from turbo flange not being tight enough? thanks Jon
Hard to tell, but yes, that could be a problem. If you have an exhaust leak that might cause problems with the air/fuel mixture.
Dear Trionic Seven on the gauge it reads 13.3 Litres per 100 kms I have the 2007 9 5 2.3T i thought that the fuel efficiency would be better i have watched your video replacing vacuum lines and was thinking about replacing my own however do you think that this reading is an abnormal amount of fuel consumption or normal for winter conditions? i am trying to drive very economically between 1200 and 2000 rpm.
Thanks again Jon
Mine is a saab 9-5 2.0 petrol mine dose not have the brake booster hose is that just for the aero model can anybody help?
Do you happen to know what check valves would replace the factory version check valve? Curious as to if you know of a metal check valve part number.
I would guess that any check valve that fits the hose will work!
Current part number for genuine item is SAAB 12793343. The item costs about 35. That's 35 dollars in the USA, 35 pounds in Britain, or 35 pounds in Europe. I know those prices don't all equal the same amount, but I looked up the price in those 3 markets and it just so happens that it's 35 for all of them in the respective currency, not sure why.
Jesse Crandle Thank you very much!
does anyone know where the small hose that comes from the gear box top and is tied to the fuse box, it apear to go open from there is it a breather hose . the size is that opf a small vacume hose on a 95 2.3l turbo model
+BoB Whitfield I think that's a breather hose, pretty sure that the transmission has one.
I cant figure out which hose go's where. can you help me I'm stuck with an engine light on because of the hose's I need a diagram
I think there's one in WIS, the workshop manual.
The first hose on 4:14 is making me crazy, where is it supposed to go? Im getting CEL and it says its a vacuum leak but this is the only place i can tell there is one, help appreciated in a hurry!!
Sorry it's been years and the car in question no longer exists. Ask in our community forum. facebook.com/groups/733705113501723/
that check valve you mentioned at 8:25, what direction is the flow? cheers.
It goes from the valve cover to the throttle body.
+Trionic Seven i know that but the check valve has a flow arrow on it.
Flow is from valve cover to throttle body, just as I said ;)
+Trionic Seven ok great thanks, great video, great channel, i love my saab 2000 93
Hi
I have one question it’s about about economic
My Saab 95 2.3t
Model 99
Take too much fuel
It’s take 20L for 100k
It’s normal or I have something wrong?
And if I have what’s wrong?
Sounds a little bit much. Check for air leaks, air filter, lambda sensors.
so i just need 3 meters of 4mm hose? i saw on saab forums that people are replacing some hoses with 6 mm. i have 95 with b205e.
+ppwpl Correct. The 4mm hoses are the vacuum lines. You might be thinking of the 6mm EVAP system hoses with blue check valves. They can be replaced too, but that's a separate video that probably will be done next year!
+Trionic Seven: For Saab Enthusiasts OK thanks m8. If i'd like to replace the EVAP hoses, how much of this 6mm would i need?
+ppwpl The only guide I know of is in Swedish: forum.saabturboclub.com/showthread.php/81210-FAQ-T7-EVAP-Tankurluftning-Br%C3%A4nsleavdunstningssystem it appears to need 2m. Although here the check valves are more important than the hose AFAIK.
+Trionic Seven: For Saab Enthusiasts thank you
Kan det här vara bra bara för att underhålla bilen också? Vart köpte du silikonslangarna? 😊
Slangarna kom från Speedparts. Ja, det är bra att göra i preventivt syfte! :)
Can anyone help me with the vacuum hose diagram I replaced the power steering oil pressure line and forgot how the hoses went

My 06 9-5 2.3T sportcombi (auto) vibrates terribly when sitting still in D. The vibration goes away slightly when i give it gas. Replaced motor mounts and it didnt really fix the issue. Anyone here have any similar problems or any ideas.
You can change the idle rpm slightly with tech2. Might solve your issue if there's resonance at some rpm.
Hi, can i use hoses with the inner diameter of 3.5mm on my 2002 Saab 9-5?
I think that will work.
I'll see if i can change them and see if that works for me... if not i can order the stock ones the local dealer.
It looks like the O-ring on the throttle body is missing or worn out? Very common that they get flat or cracks. Very cheap and easy to replace! I recommend to change that when you have the inlet pipe removed like when you replace vacuum hoses. Saab original costs about 9 SEK. OEM-no: 4940698
+Bersa33 Good point!
What you called the brake booster is blanked off on mine??? Should I be worried or is this some sort of mod?
+Glenn Travers I probably should have mentioned in the video that cars with automatic transmissions have the hose going to another outlet. :)
So if this is blanked off is this normal?
+Glenn Travers I think so.
I have an automatic from 2004 and it has a mechanically driven vacuum pump on the LHS(seen from driver seat) of the cylinder head. I do not have the booster venturi or the pipes. I also wondered what the blanked off hole in the charge pipe was.
That's right! I only drive manuals 8)
Hello I got a saab 9-5 turbo -03. My question is, do all saabs have a break booster (host?) - the pipe he pulls out on 2:06? I have the red thing and everything and it looks exactly the same as his saab but i dont have the pipe? Thx
Read that its because of the automatic engine so nvm :)
That's right!
Måste jag ställa om batteriet kanske också?
?
skitsamma
what is wis and mine is the 3.0 and what is the little vacuum pump on the firewall called
Check my WIS video
My 2004 Aero Wagon didn't have that "t-joint" 6:05
You forget the one on the turbo 😉😉😉
hey there, where did the silicone connects to at 6.52? :)
Must have been an editing mistake :)
So, it goes to no where? Because I do have the same pipe and can't find where it connects to...
I have some questions how I can contact with u?
