*NOTE: When I made this video I was in a slight hurry to get the job done so it may be missing some details and is not super in-depth. Mainly designed to just get give idea of what the job entails with some good tips as well. This is not a complicated job however the video may make it seem a little easier than it actually is..
Quick video on basics of diagnose/replace the heater core on this 2014 VW Passat. this should carry over to a few other years and models. If you know which ones, please feel free to comment. When replacing the heater core, it is highly recommended to flush out the entire cooling system at the same time. `

My advice:
-Be sure to add a good amount of lube to the oring and tube mating surfaces. (I use silicone paste lube.)
Hopefully that will help the tubes slide into one another smoothly.
I really had to manhandle those aluminum tubes. I ended up using a plastic wedge tool against the heater box to lever the tube flanges into position to finally get them fully seated. It was kind of a pain.
- I also cut the tubes from the old core to make removal easier. I sprayed some penetrating oil at the mating surfaces beforehand.
Next time I will probably flush it before replacing. Its all a very tight fit under the dash.
I also think I read that VW has an extended warranty on these things, so they might do it for free. I like to do this stuff myself.
The creator of this video is definitely a skilled mechanic.
I just don't understand why more engineers cant design core replacements like this ! great video thanks !
Volvo has all the cars til 2007 like this. Good luck
Thank You thank you THANK YOU for this video! This job can take less than an hour to complete.
I paid $26 for an O.E. heater core that was on sale at a local dealership (same car). I stopped by the service department to get an estimate for the job, the tech was gonna charge me $60 for the exact same part (from the exact same parts counter I had just paid $26 to) and quoted me $1000.00 for the labor.
Had I not seen this video I'd have been ripped off by VW!
Thank You again brother!
I'm looking at buying a used 2013 Passat that I think has a heater core leak... now I know I can replace the heater core myself! Great quality video
I just changed my heater core on my 2014 Passat TDI after watching this video. Thanks to you! Had an issue though since my pipes going to the firewall are aluminum and clamped on pretty snug. I went into this already planning to take the whole dash apart to get to it so when I saw this, I figured Id try it and if it failed, I'd just then take the dash apart to do the work. My work around the snug aluminum pipes attached to the heater core was to actually just cut the pipes on the heater core itself from the inside. I then was able to pull the core out then detached the pipes I cut. At that point, the aluminum pipes going into the wall were loose enough to move around to barely make space for the new heater core. Put the clamps back on and put everything on like a charm and now I have heat!
Josh Ferrer thanks for the comment and glad the video helped out some!
Yep! Loosen the 6mm clamps, then cut the pipes into the heater core and then twist them off from the pipes going into the firewall.
How did you snap the line from firewall & lines from heater core back together? Bottom line snapped perfect but the top line has a gap & will not snap into place. I'm stuck st this point. Used oil but no luck
@@luvnRain3421 hello did you find any solution for this i have same issue with my 2014 passat
Josh, is there any play in the tdi aluminum hoses coming in from the firewall? I'm worried that I can't get enough space to not ruin the connection. Can you tell me how you aligned and push the new fitting onto the pipes from fire wall?
Thanks for doing all the prework before filming but still explaining how its done. You the man! More vids for a VW CC please :)
Glad to hear you found it helpful, and I really appreciate your comment! Helps out the channel. And I only do videos when we have slow days at work, which lately has not been very often. So I try to put up whatever I can
@@NoNonsenseKnowHow I just bought the heater core for my 2010 vw cc and hopefully can follow this video to replace it on Sunday. Keep it up!
@@NoNonsenseKnowHow is this the same for a 2004 passat
@@williamdickson4223 I'm not sure. They based on my research when I posted the video it was for 2009 2017
I found the joy of the banding clamp at the bottom of the air intake hose at an obtuse angle..............................
you were amazing in this video, you helped me solve my problem, i spent the day disassembling the car and looking for this part to change and you showed where it was in a direct way! thanks
Great vid!! I have to replace my heater core on my 2009 Jetta. I was told the entire dash had to be taken out! Thanks!!!
I totally agree about your comment about modern aluminum heater cores vs the older copper and brass ones. In Ford Freestars, they tend to electrolytically scavenge the aluminum and spring leaks from the resulting pinholes. After having three core leak failures in two years, I took a NOS brass Ford Ranger heater core that had the same core dimensions and fabricated the copper inlet tubes from plumbing joints and copper tubing. The van has now run three years with reliable heat and no coolant leaks.
I'm facing a plugged heater core on a 2012 Tiguan (passenger side cold air, drivers side hot) and will see if your procedure works on it. If so, I'll report back and you can add it to the list of applicable vehicles.
Wow, that's awesome that you did that. Yeah copper ones are definitely the way to go!. And okay. Good luck with the repair. I appreciate that
Bro, nice job. I've been looking for someone to replace this on a newer model. Alot of vids mention about simply irrigating the core out with CLR instead of buying a new one.....im up in the air about what to do...till now. I appreciate the vid
Thanks so much. This video is amazing. I really appreciate the detail. Got this done in a few hours (I'm slow!) and saved me over $900.
Glad it helped! Thanks for the tip!
Im having the same issues with my '12 VW Passat SE 2.5L. This video was very very helpful to understand how-to fix and replace the Heater Core on a VW Passat!! I wish you were in my city fix my VW Passat! Lol! After watching your video I think I can fix & replace the Heater Core in my VW Passat.
Thanks for making this video!!!
Good thing VW redesigned the heater core access! I had to replace the core on my previous Passat B4 and had to remove the entire dash, that was a pain! I now have a 2011 B7 Passat, but mine's a Euro version, not sure if it's as easy as the US version
Thank man, followed your directions and was a quick fix. Thanks for posting.
Well done mate, very nice touch for cutting it up and showing us the inside 👍🏻
Thanks Peter.
Thank you for taking time
I have the same problem
I can do this my self
Thank again
Excellent how to. I was expecting a bear of a job having to remove dash. Can't complain though, mine's got over 200k miles. I suffered with no heat last winter. If only I'd seen this sooner !
Thanks. Good luck on getting it taken care of
very good video, no waste of time & to the point. You're correct about the older ones....replaced one in my old 98 jetta years back and had to take to complete dash out!
Changed with these tips today in 2 hours total. Thank you! Only difference in vw passat 2010 b6 is that the hoses that goes throuh the firewall are aluminium not rubber. Had to break pipes from old heater core to get it off. But heating works now on both sides 😊
What do you mean by brake pipes? My vw cc has metal pipes too and I was not able to get the heater core out because of this.
@@SalvadorSTMZ i am having the same issue, i cant seem to be able to slide the aluminum tubes apart
@@richhackenberg8 did you find a solution for this?
Used a Dremel and cut the aluminum pipes on the heater core then just pliers to wriggle the stuck pipes ends out of the tubes leading to the firewall. Then replaced with new heater core.
I have a 2010 VW cc Passat with over 107,000 miles. Just took the car in because of no heat coming on the passenger side and rather low heat coming out of the vents on the driver side. I thought it was a bad temperature sensor but turns out it is a bad heater core. After viewing this video I feel pretty good that I got almost 10 years and 107,000 miles out of the heater core before needing a replacement. I am relieved that the core comes out quickly as I was concerned about having to remove the entire dash. While the core may cost on a few dollars - parts and labor run over $1,000 where I live. But hey, thanks for posting this video.
That's pretty good. I've seen them go bad countless times at much earlier mileage on these vehicles. Thanks for sharing
First off, great video. Super helpful. Really appreciate the time and effort you put into helping people.
I have a 2015 Passat TDI. 187k. It’s on its 3rd heater core. 1st two replaced by the dealership. I’ll be doing the last one myself.
Even with coolant changes, the heater core and radiator have gone out on this. Really sad designs.
Excellently done, very professional, I wish you were here in Vancouver BC to have my car fixed
YOU SIR! ARE A CHAMP!!!!!!!! You just yourself a new subscriber!!!! More vw vids!
My man! Thanks for the subscribe.
Thanks for the video! This worked great for my 2013 2.5L. I blew the coolant out of the old core and didn’t spill a drop in the interior. I had trouble separating the top pipe from the core as there is much less flexibility than in the bottom one, even with the screw loosened. I wound up cutting the core pipe with diagonal cutters, pulling the core out and then using pliers to remove the remaining core pipe stub from the water pipe. If you cut the core pipes it will save a ton of time during removal.
Jeremy Schemm did you have any trouble putting the new one back in? We also cut our old one out like you did but now we're having trouble getting the pipes to come back together.
Hello Ashley, did you find a solution ? I have the same problem. I spent 3h this morning to try to remove the heater core. But impossible to separate the core pipe. Before cut them, i will be sure that i can re-install the new heater
@@ashmiramant did you ever get yours to connect? Bottom connected after wrestling with it but top seems too short.
@@maestro8266 unfortunately not. We ended up having it towed to the shop and finished there which killed me because we got charged just as much as if we had just given it to them from the beginning. We were having that same problem and just couldn't figure out how to fix it.
@@ashmiramant thanks for the reply. Sorry didnt work out for you. i got it to come together once but it leaked. Having a hard time getting it to go back over the new oring now:[
You are a lifesaver, thank you
Great video. I have a mk7 gti that is blowing lukewarm. Hope that it's constructed the same way....The job doesn't look too bad, thanks a ton!
Horatio Time Waster same problem. VW says it’s my heater core that’s broken at 42k miles. Already out of warranty.
Tiguan heater core replacement is a mayor pita! Great video.....
I can imagine! I haven't done one before!
Great to see VW making heater cores more accessible.
Yea
Dude, this was a freaking great video for sure! I have a 2.5 2013 Passat- and it’s been AMAZING for the last 8 years I’ve had the car until this past year. (The car is still amazing). I just have to replace the heater core because I don’t have heat on the passenger side 🥺
I have a 2013 turbo Beetle with same problem, did the core replace fix your problem?
Perfect Video Brother!!
Thanks for the video. I have a 2011 GTI with a plugged heater core. I was able to get to the heater core inside the car (very similar to the Passat) but because of the tight fit, I am not sure how to pull the inlet and outlet hose out. Is loosening the 6 mm screw inside the engine compartment will give a little more wiggle room with the two hoses? Is this why i have to loosen the 6 mm screw? Thanks
Appreciate the video, can you maybe give some info on what we’re draining and re filling, it’s it same coolant that goes in radiator? Would it be smart to flush radiator when you do this and put all new coolant in?
Hello, thank you for the video for replacing the heater core. Could you do a video for replacing the evaporator core for a 2014 VW Jetta?
Video is great! I have the bottom hose disconnected, but can’t seem to get the top one to come loose. Any suggestions?
*UPDATED BELOW* Thank you for the posting this! I have a 2013 Passat 2.5 and at 54k we lost nearly all heat on the passenger side. The car has run flawlessly excluding this issue but the stock heater core, as you mentioned, is VERY poorly designed.
This heater core change isn't as easy as changing the core in my 91 Audi 200s (30 minute job) but it seems definitely doable for any average mechanic like me. Certainly beats paying a 1000 plus to the dealership..Thanks again for your tutorial and adding to my confidence on this job! New sub!
20vtechnik No problem and thanks so much for the subscribe! glad to hear you're going to take care of it yourself instead of paying top dollar at a dealership. Also thank you for sharing your model/year and symptoms.
I should have updated this sooner but better late than never.. After digging deeper into my lack of heat problem (passenger side) I found the issue. It was NOT the heater core but a simple temp sensor in the passenger side vent in the dashboard. VW part # 3D0907543A. I replaced it for about $30 and it completely fixed the issue!
20vtechnik awesome! Glad to hear you figured it out and thanks for updating
i have the same exact issue on my 2013 Passat SE. I figured it was not the heater core given the left side heats up perfectly. The warm/hot air just isn't getting to right side vents. Can you elaborate more on how you accessed and replaced the temp sensor. I was thinking the issue might be have been a bad blend door actuator... but I would like to hear more about how you diagnosed the temp sensor failure, please ! And thank you for posting this.
On the 2013 Passat there are access panels on both sides of the dash. One on the drivers side (which also contains the fuses not found in the main fuse box) and one on passenger side. Open the front car door/s and look at the side of the dashboard and you'll see it. You can use a flathead screw driver to pop the panels open. You will see an electrical clip that is attached to the sensor which runs into the plastic venting system. Twist the clip to carefully pull the sensor down from from the vent then disconnect the clip from the sensor. I simply switched the sensor I knew was working (drivers side) and swapped it to the passenger side (and vise versa). Then I turned the car on, let it warm up and checked for heat on the passenger side. Now, heat on passenger, none on driver.. Hopefully this is your issue and not a faulty blend door actuator. I've heard those are a bit more money and take more time to replace. Check the 1stVWparts site if you do need a new sensor. Hope this helps!
Hi, my Vw Passat 2013 r-line with 43k miles on it well it’s in the car garage atm because I’m getting smoke inside the car, I’ve had a new fan with resistor fitted but 3 weeks later my garage has said it’s down to the auxiliary heater that has failed as in a week of them having my car the mechanic has seen smoke coning from the passenger side footwell it only happens when the outside air temp is below 5 degrees so I’m assuming the auxiliary heater is kicking in to warm the coolant/inside of the car faster, I’m trying to get myself knowledgeable on how to take it out so I can let others know, is the auxiliary heater fitted along side the heater core ?? Thanks 🙏
Question about the two aluminum pipes connecting to the Heater core inlets. Did you have to push those pipes forward by pulling from the engine compartment?
Thank you for a great video.
Going to change mine tomorrow since I have a problem . ( passenger side is blowing colder then driver side) & if blower in hight position the air is getting colder slowly.
Thanks again
No problem! Thank you and good luck on the repair
Thanks for the video looks easy enough!
Easy peasy . Thank you that was awesome
No problem!
Great video man! Thank you!
Thanks and no prob!
I am having the issue on a 2015 Jetta of cold air blowing on the passenger side and hot air on driver side when the heater is on. My car does NOT have dual zone climate control. I opened up the area where the blend door is located and it appears as if both doors are opening/closing when changing from hot to cold air. Do you think it may be a heater core issue?
Sir, thank you. I do have a question, what if heat is coming out of the driver side and not the passenger side (single not duo settings) and after about 30 min then hot air comes out the passenger vents. Same with defrost. What would be the issue?? I have a 2012 VW Tiguan.
I'm on my third heater core in the past 14 months, I've driven 25k miles in that time. I have a 2014 Passat TDI, it's still under the VW warranty after the TDI recall. My dealer tells me they flush the system each time but don't think their are because there is still sentiment in the holding tank. My option is that the dealer makes a lot of money doing heater core replacements that they want the customer to keep coming back with clogged cores. This heater core replacement look very easy and once my warranty expires I will be doing myself, plus I will make sure the entire system is completely flushed.
Wow, that's crazy that you've had three of them already. I wouldn't doubt that they are skipping the flush as well. Unfortunately it seems like just a poorly designed core and set up. Maybe try using a really high-end engine coolant that has a lot of anti-corrosive?
I am putting in my second heater core in my 2015 passat tdi in 10 months. About 25000 miles.
@@brdman55 that sucks. Yeah these are definitely a poor design. Maybe somebody will make an aftermarket heater core that is better quality.
I have a 2012 2.5 se and the same problem cold air from the passenger side with dual climate control. If I turn on the recirculte I get hot air again but the windows fog up. I saw a video from a European version and they replaced a thermistor from that side and it worked. Was this car in your video dual climate control? If not would a thermistor cause this problem.
P2457 code a symptom as well? I have the heat issues where it blows hot for like 15 seconds
Great video. Quick question. I have a 2014 passat 1.8t. I notice my heater is not producing hot air from the vents. it only gets warm. I also notice the passenger vents are noticeably warmer than the driver side. Actually the driver side barely gets luke warm. Is this a Blender issue or heater core issue? I have seen comments suggesting that it can be either or both.
Thanks again.
Thanks. And correct it could be one or both. These are extremely common for clogged heater cores. I actually just did one today at work

@@SENSUI347 If you have auto climate controls & heat only from one side, then the right blend door is stuck or actuator may have failed.

The firewall hoses with the clips , do you twist them off or pull them off?
Hey can it be the heater core if only half the dash driver side only is heating and passanger side is cool?, no other problems are occurring like overheating or blown head gasket
Great video! Thank you!
Thank you! Great job
WELL DONE!
AND I THINK THIS JUST SOLVED MY PROBLEM!!!
Any suggestions for when reinstalling cant get heater core hoses to go back in all the way.
Leave them with a little bit of motor oil or coolant
Bloody hell that was easy!!
Great video!! One problem I'm having on my 2013 Passat TDI is accessing the 6mm bolt on the fire wall. There's a big something in the way (turbo?) and I can't even come close to putting my hand in there much less a ratchet and socket. Any ideas?
Did you remove the plastic cover that sits across the top of the engine?
Hi, are there pipes in there that could vibrate against covers or each other to give a tinny rattle?
Thumbs up 👍 yes on old coolant change it out😊
Great video thanks for making it. I drive a 2013 Passat with the 2.5 motor and it has been great up til now. Last night coming home from work it got up to operating temp as normal and I turned on the heat. The blower works fine as usual but nothing except cool/ cold air from all vents. I tried switching the a/c on and off but that didn't do anything. After seeing your video, I think it may be the core but I haven't tried to see if there are any blown fuse yet. What are your thoughts?
Monty Powers thanks for your comment. Start by checking the heater core hoses as described in this video. If the hose flowing coolant into the heater core is hot and the one coming out is cold then you can assume a clogged heater core. If not you would need further diagnosis. However in your case it sounds like it just happened all the sudden one day. So you may have an electrical issue going on. Usually heater course fail slowly and get worse overtime. Lmk how you make out.
Good job.
Great video! Frustrating in that i have the new heater core in but the connector pipes won't fully reach the pipes on the core. About 1/2 inch to go before the connector clamp will work. Can I just connect the 2 pipes with a heater hose and clamps?
Thanks. And they may not be lined up properly. They should be able to force in to each other. Butt all the way tight and then the clamp holds them in place and seals them with the O-ring
Im getting same problem did you find any solution for this not able to connect the pipes
Thanks for the helpful video, I have a problem, my heater core is plugged up and it's restricting the flow of coolant through my EGR valve cooler so I have an engine light coming on plus my heat didn't work in the winter time so I knew it was plugged up anyways my daughter has the same car 2014 Passat she had the same problem the coolant that they use in these cars I think is a big problem
Thank you really clear your video
You're welcome!
Thanks, gonna put one in tomorrow
Sweet. Good luck with it. And no problem
FYI, there is zero info online for doing this to VW, CC but the procedure works out 100% the same for at least the 09-12 models. I tried to do this without disconnecting the lines at the firewall and loosening that bolt and it is impossible to do without doing that first.
So, it is the same on an ‘09 vw cc ? Just want to make sure before buying the heater core... Thanks
Thank you great video. Could you do a video for replacing the heater core for 2017 vw jetta
No prob. And maybe sometime in the future if I run into one that needs it.
Did this and it works amazing thank you where do you get your repair info from
No problem, glad to hear it helped out. I get my repair information from all data and Mitchell
I just flushed my coolant a month ago. Is it necessary to drain the coolant? Or will it spill everywhere once you disconnect the lines?
It's a good idea to drain some before disconnecting the hoses if you don't want to create a mess. Or just put a pan underneath to catch the most of it when you disconnect the hoses
Hey man what's the panel called that you removed after the little tray thing? I need to order a new one. Also do you know the part number for heater core access panel
What is the time stamp in the video where the part is?
Great! Thanks for taking the time.
No problem man! Thanks for taking the time to leave a comment. :)
@@NoNonsenseKnowHow Hey man! I think I might be having this problem and I have a question, do these come with a flow control valve or fluid just keeps on circulating constantly? Trying to figure out whether the problem is heater core related or not. Thanks a lot!
@@The3lloba I'm not sure if there is a flow control valve on these or not. My guess is no I don't think there is one. These are extremely common to be clogged up though I will tell you that much.

@@NoNonsenseKnowHow I see what you're saying! Thanks I really appreciate it..
@@The3lloba no problem man, good luck on the repair. It's a pretty easy heater core to do for sure
Is this the same construction as in the 2011 polo? 1.2 diesel.
Very helpful
I have a 2013 vw Jetta gli with the same problem. Any idea if it’s the same set up?
Honestly I don't recall. I think it's basically the same thing. But if you look down in the comments, I think somebody may have asked the same question a while back. sorry I couldn't be of more help
Great video....
Do you have to unhook the coolant line in the engine bay going into the firewall? It looks like that wasn't needed.
Yes because you want to drain the coolant. You don't want to spill inside of your car. If you unhook that hose and then blow out what's inside of the heater core you're much less likely to spill inside of your car
hey after installing how should i fill the coolant back up and how much will i need
Megan Heck once you have everything back together just fill up the coolant reservoir until it's up to the fill line and let it run with the cap off till it's up to temperature. To burp out any air. I'm not sure what the coolant capacity was. Probably something like a gallon and a half
The plastic lines at the fire wall I have the clips out but cannot get the line to pop off is it just seized or is there a way I need to turn it? Thank you
One of the main reason why they plug up is from not replacing the cabin air filter. I recommend replacing that as well. Supper easy to replace. It's on the passenger side under foam thing with finger tight plastic clips.
Wow this is going to be so easy😄🙌🙌🙌
was it that easy?
Hi . I am driving vw passat 2013 2.5l . Driving side vents are blowing cold air and passenger side warm air. Its winter its getting hard now. What you think could be the issue and how can i fix it . Thanks
If you read down in the comments, a few people had a similar issue. If one side blowing hot, then a clogged heater core is not your problem. Sorry I couldn't be of more help.
Will a clogged heater core make the engine slow to warm up? Great video, Thanks
Not generally. Usually a stuck open or worn out thermostat spring will cause that. Clogged heater core will cause it to take much longer to get heat though. And thanks
Do they make a after market upgrade of the heatercore ,not aluminum,but a bronze/copper material ?
Not that I know of
I have a 2015 Passat with no air coming out off center vents and very weak on outside vents. No heat as well. Do you have any ideas? Thanks
No heat is probably a clogged heater core. But you would need to take some of the steps that I went over in this video to verify that. And as far as the weak air,, if you read down in the comments, a few people had similar issues and discussed the fix
Hello, does this video applies to vw polo gti (6c) 1.8T 2016?
My polo has no hot air anymore!
Thanks in advance.
I have a 2014 Passat TDI, do you have to drain the coolant before removal? Thanks Jeff
I’m about to do the same and can’t find any answers, but I believe if you keep the lines up after they are off and don’t let the let’s go lower gravity will keep everything in the system. About to find out the hard way though
Great video. How about on 2013 Passat that blow hot air on driver side and cold air on passenger side? It is winter time so want hot on both sides. Car does not have dual climate control so I am baffled on what might cause this.
Thanks. If you read down to the comments, a few people had similar issue and discussed it
Does Volkswagen cc have blend door actuator or would that be the heater core clogged?
They do have a blend door. If you follow some of the tips in this video you should be able to verify if it is the heater core or not. Or if you look down in the comments, some other people spoke about the blend door
Lubricate O-Rings with what??🙄
Also, can a bad Heater Core cause annoying interior window and windshield Fogging? If so, can you explain why this fogging is occurring?
This is what is happening with my 2015 Passat TSI Wolfsburg edition windows & windshield.
I am still trying to troubleshoot the issue to see if I can do something about it myself. I have no heat coming out of the floor vents specifically & with winter upon us in MI, it's a problem.
Heat seems to be coming out of the top/mid-air vents mostly okay (though I have to sit in the passenger seat to see about the far right side since many people are mentioning that specifically). My front windshield defroster action is definitely not great though.
If you can push the hose forward from inside the car, is it really necessary to disconnect the hoses in the engine bay? Great tutorial btw!
Been a while since I did one of these so I couldn't tell you for sure. And thanks!
Bravo bravo grazie mille
having trouble getting 4th 6mm screw off heater core panel-its under the blender (yellow tube)
any tips? thanks
I used a screw driver to barely pry away. I might not reinstall.
Do you know if this is the same as replacing the heater core in a TDI?
Yes
I am going to try flush mine. Which of those pipes is inlet?
Same process for 12’ Volkswagen CC?
Good information
I’m having the opposite issue. 15 Passat 1.8 TSI, ac is working on passenger side but not on drivers side. When fan is off I can feel the cool air creeping out the vents but once I turn fan on it goes to warm air. Same heating/cooling system in video, not the climatronic. Heat is fine on both sides. Any ideas?
I'm 4 years too late but that would more than likely be an issue with the temperature flap actuator under the dash
What happens if you remove the 6mm bolt between the heater hoses?
Great video, I have a 2013 Volkswagen CC and it has no heat… sometimes it does.. and other times it doesn’t. More times it doesn’t. So the vehicle doesn’t have heat and it over heats at idle. It seems to stay at 111C, a little past 190F on the cluster gage.
So precious owner had the bright idea to put gasket leak fixer additive in the coolant. He thought the vehicle had a bad head gasket…. So I flushed all that nasty coolant filled with that sparkling additive as much as I could with distilled water and added real G13 coolant. Vehicle still doing the same thing. Any suggestions would be appreciated. Also…. No check engine light or codes.
Hi,
Great vid. One question.. On golf mk7 (2014) do you need to take out the dashboard in order to replace the heater core? Or you can access it in the same way as on the 2014 Passat?
Thanks.
+zolilwtf honestly im not sure off hand. I havent replaced one yet
I managed to get a repair manual for mk7 golf and pretty much it says you can do it the same way you did. thanks again.
Zoltan K. I need to do my golf! Can I ask if your in the UK? Where did you get your replacement matrix from? And this repair guide you speak of?
Unfortunately I'm not in the UK. I got the heater core from a local shop in my country. Basically there are two types of heater cores for the golf MK7, you either have the VALEO or the DENSO. (You need to unmount the plastic cover and check it before buying one) If you have the VALEO type like I do then the part number is Valeo 715303.
If you have a knee airbag like I do, you will need to unmount it as well :/ You can find the Golf mk7 repair manual online.
Zoltan K. Thanks for the reply! The weather is terrible here at the moment which is a brilliant time to have a blocked matrix 😂 fortunately the heating is working a little and is enough to cope with defrosting the glass. Im unsure if access to the matrix will be on the drivers side on my car? (right hand drive)
I am getting rdy to do this same thing. Seems like once a year my 2014 needs a heater core. Last time the dealer did it since it was their problem. Did you have to bleed the coolant lines after the replacement?
No, you just have to run the engine for a little while and burp the air out of the cooling system
@@NoNonsenseKnowHow sweet thank you!
@@NoNonsenseKnowHow time for me to replace the core yet again.... . such lousy cores. glad their cheap. 15 bucks from fcp.
