- **** PLEASE NOTE***** This was the first time I mounted the idle air control valve upside down like that and it caused idle speed problems due to the reverse vacuum flow. Mount the idle air control valve right side up. www.johnny5troopers.com / johnny5troopers-112695...
Tap size for the Temperature Gauge Sending Unit is 1/8-27 NPT
thank you!
Holy crap. This video is a godsend. I just replaced the clutch in my 90 trooper 2 and was so worried after discovering all the vacuum lines and other BS the california car has. I will promptly be deleting it as well as all other unnecessary components of the engine. Thanks! I should add that it is worth it to me to do this as my trooper is 141000 miles and I am the second owner. I am very much interested in keeping it.
Thanks, I've been putting off changing my temp sensor (have a new one in a box) just cause it is such a trick to access it. My AC valve is just taking up space. You are a genius!
I’m always looking at making life simpler with my Amigo 2.6 and always looking to make it a bit simpler than they designed it.
I agree, there design in upper coolant system is a bit much and their placement of intake sensors were ill conceived.
Thanks for the video.
I am a new trooper owner so forgive me if I'm relaying something that was discovered years ago. I thing the igniter that you mention as not being documented is listed as a Power Transistor on page 03-48 Emission Control and shown as a Ignition Power Switch on page 01-75 in the 1988 Trooper II (KB84) manual.
Excellent stuff Johnny! I have a later model which has different ignition control module (igniter as you call it) and it was a bitch to reach even with the front right wheel off and fender liner detached. Great tips and tricks Johnny. Thanks - Oh and I have a wiring diagram for the igniter etc if you still want it @Johnny5ive
Great information!
Hey Johnny, thank you for putting out these videos.
Having my 2.6 remanufactured so I'll most likely add this process to the project. Thanks Jonnhy5!
I may be late commenting here but I purchased the ignitor on rock Auto, only place I saw mention of it.
I got a bronze 1991 Isuzu Trooper 4 door it been restored new paint sharp looking I get stares everywhere I go it is nice take it everywhere fun to drive had a local tire shop change the temp sending unit up under the intake showed him where it was from under use a long extension got a new one in there basic went thru and put new stuff in all the stuff is able to remove just got to be a contortionist and bend body parts in funny ways helps to be tall crazy thing I find it does alot is idle up and down doesn't take much to throw the whole works outta wack
Will the air conditioner work? Also was there any issues with not capping off the fuel pressure regulator? I notice that there's not a vacuum hose going to the top of it in your video when done.
my intake gets really hot in the Aussie summers i cant even touch it. your 5 tec mod should fix it and make my life 1000x easier later down the track
Hey man this is genius i have a bad IACV that i couldent find to save my life this video was very useful thanks
i have a 92, 2.6 , 5 speed ... i am looking to simplify my i tec .
my truck runs great , but it is old. i would like to stay ahead of the problems...
thank you for the vids
Got a question I'm in the process of rebuilding a 90 isuzu trooper. And eventually I'm swaping the 3.2dohc. But until I can get the rest of the stuff needed. I'd like to make this run better. How do you delete the air pump shit. Don't need it where I live.
Before I watched this, I have started to do all these mods. Nice to see some validation! what a mess the intake manifold is on these.
will the air condition work the same with this modification?
@@melaniusst.hilaire1003 yes I believe it will.
@@Jdes9924 okay i will do just that to prevent future problems..thank you for the info
John is the go to feller on just about thing mechanical
I have the service data on your ignition coil and power transistor. It's in alldata under ignition system.
Can i do the coolant temperature sensor relocation if i still run with A/C?
Very nice ! What happened this trooper genius !!!!?
Taking the hot water out of the intake will work fine in warm climates and may even create a performance gain, however it will be problematic in cooler, more humid climates. Ice WILL form in, on and around the intake and be problematic.
Also, I did not see your fuel pressure regulator - what'd you do with that?
Where would I get all the parts for this mod? My parts store clerks are no help at all.
+Johnny5ive where did you put the fuel pressure regulator that used to be mounted on the front of the intake box where you relocated the Idle Air Control Valve to? I didn't see it anywhere
I would also like to know info on this @Johnny5ive
Did anyone ever get this figured out? I have the same type of set up where the fuel pressure regulator is mounted in front of the ITEC housing. I am going to route it off to the left hand side. Has anyone else done this??
thank you so much for this it so hard to find easy to understand information now a days I'm in Nevada and have no regulations can I delete the smog pump as well?
I purchased a pdf tpye manual for the Isuzu rodeo from eBay and it has documentation of the said ignition igniter
Can you email the page to me please j5@johnny5trooper.com thanks!
Johnny5ive I've sent you an email mate.have a good one.
I’m running into an issue of my 2.6 top end rebuild. If I turn on A/C, idle drops drastically to all but shutting engine off?
I’m assuming I’ve got a vacuum line or 2 off, any help in addressing it would be appreciated and save me some time.
Thank you
Hey Johnny,
Do you recall what plug tap size you used to thread the hole for the coolant temperature gauge sensor?
Did you ever figure this out?
Aye LongJohnny5 yI'm guessing not but would this apply to the itec in early Impulses/Piazzas? Running the 1.9 G200w thxddeeeeeeeeeeeeeeeeeee
thanks for this video, my 91 Jackaroo (Trooper in Australia), decided to split one of those nasty hoses and i emptied most of the coolant to my driveway, lucky i was home, so pulled off the manifold and followed your steps on modification of those hoses and other bits and seems to be running much cooler now :) by the way, for a future modification, would it be possible to move that bypass T that connects the heater to the coolant that resides behind the back of the engine? possibly just over 20-30cm so we dont have to deal with any coolant hoses behind the engine.
Could you do a more detailed vid on what vacuum lines you got rid of and what you kept? I'm trying to get rid of as much possible errors as I can on my trooper. Also, did you notice any mpg differences or power issues?
it looks like in the video there isn't even a vaccum line on the fuel pressure regulator?? can this be true? john could you please help clarify vaccum routes?
Will Roberts i just deleted all unnecessary vacuum lines and my trooper runs better without the vacuum hose on the fuel pressure regulator. I tried with and without. Got a box full of stuff I didn't need when I was done. Truck runs great!!
Patrik Strock what about EGR?
@@lukecarswell3275 you ever figure out about the EGR?
I know I'm a little late to the party, but I have a question about what you referred to as the Ignitor at around 3:10 in the video. I have some info on it, in case you haven't discovered any yet.
Do you have any idea where the ignitor plugs into? Maybe what color wires or a picture?
i know this vid is a bit old, but disanyone able to either link me to, or email me a step by step guide? i gotta rebuild mine soon [australian delivered rodeo, so no smog pump] and wanna simplify it as much as possible
Kieran Stevens did you find a guide? I just bought a Rodeo (Australian) and plan to do such a mod in time.
Where are you at and how much do you charge to do this to the 2.6 gen 1 amigo? I’m in Alabama.
Very informative, thanks for posting this.
You're welcome buddy, I hope it saves a lot of people a lot of headaches.
@@Johnny5troopers can you help me get a parts list for this mod I can't get any help from my local parts stores . They are all on drugs or too young to care.
Hey so my truck has spark n gas and still won't start please help me
i'm doing this mod and the proyect got stop because i shatter the thermostat housing, it's being a pain trying to get it at the local auto parts, any ideas i'm from Puerto Rico (88 trooper)
+jrodriguezlugo072 I can send you one, no problem. email me john.scharnhorst@gmail.com
Nice.
Is it necessary top have vacuum running to the top of the fuel pressure regulator?
Clayton Mills no
The threads are mpt
MPT is really just ASME standards, but they don't go as deep as the ASME threads go. Drive your standard pipe tap in a little bit further, and they will fit. BTW: It's not MTP, it's JIS.

You seem like a very knowledgeful fella.
I own a 1992 isuzu rodeo 2.6L 2wd with mua5 5 speed. Basically the base model.
I am not sure how many miles are on this isu. I bought it with 273818. But i think they switched the old 4ze1 with a junkyard one.
Anyways it does not use oil, i had head gasket replaced, valves and springs and guides, timing belt, water pump, fuel pump, spark plugs, spark plug wires cap and rotor and timing checked.
It seems to have plenty of power up untill 4th gear. On the highway it has a hell of a time keeping up at 70mph on 5th gear. It does not matter if the gas pedal is all the way pushed. It just does not have power.
What do you suggest i can do to improve my isu highway performance. I want to be able to pass cars easier?
Or are these 2.6 just plain gutless?
That's gonna be really hard to answer without being there. The engine could be low on compression, you could be running too large of a tire, clogged catalytic converter, any number of issues.
I have 30 inch tires on it at the moment.
I am thinking about ditching the fuel injection for a carburetor setup.
About the exhaust pipe. What would be the biggest size we can run these 2.6 on?
2 inch 2 1/4? Or 2 1/2 inch.
I want to remove the catalytic converter. I will redo the exhaust.
Any imput is greatly appreciated. Thank you
2 1/4 is a good size exhaust for the 2.6 30 inch tires could be part of the problem, they're heavier than the stock 235/15s and the rolling circumference is probably a little large for the higher gear ratio of the rodeo. Sounds like it's just a culmination of tired motor and too much load.
Thank you johnny5
I will redo the exhaust on that pipe size.
When this tires wear out the next set i will go back to factory size.
Johnny5ive interesting
My junk 2.6 wont idel i done changed everything i know of about ready to sell it or burn it lol
do you even need the coolant temp sensor if you not running idle air control? wanting to get rid of my temp sensor so i can put a thermo switch in its place
David Leeal you obviously have no idea how fuel injection works. You can try to one-up my design or just trust that I actually do know what I’m doing. Your choice
basically i have gotten rid of the clutch fan and am installing a electric one it. this requires a thermo switch on the hot side of cooling . and yes i have no idea what iam doing thats why i asked. iam not one uping anybody just having fun with my old ute 93 aussie rodeo
I have been running your 5 tech system for 6 months now no dramas thank you for the content
@@mrleeal Just install a Honda coolant temp sensor in a TEE fitting in the upper radiator hose where the coolant AFTER the thermostat flows to the radiator.
I used an old Open Kadett electric fan and the Honda sensor and it's been running for over 20 years and no troubles so far. I also added a manual, lighted rocker switch to the same relay that drives the fan since the Honda sensor cannot carry that much current.
@@SurferJoe46 i finished up welding a tapped bung to the back of the alloy radiator worked a treat
Man anyone made a parts list for this mod?
Can this modification be done without removing the intake manifold?
No
@@WorkableWax thank you for that bit of information looks like I got some more work ahead of me
nice job bro
Iknew toud say that haha just because i still have that impulse setup
Do you think this would still passed smog in California
it will not
+Johnny5ive man i really dislike this state and can't wait to move away. glad I asked. Thanks for the response and all your hard work putting together all this information for us. It's been a big help the last few months as I have undergone the restoration of my 1990 2.6 nicknamed the Plow. Should have it running in the next few weeks.
I would still relocate the ignitor and idle air control valve just for convenience.
@@cah27118 It's NOT a California-thing. It's a FEDERAL thing that California just decides to enforce like a growing number of states are doing now too. If you come into MY shop, I'll bust you in a heartbeat - the air is bad enough here as it is and I have COPD from VietNam - so suck it up and keep the emission controls where they are.
If I remove the EGR which come consequences?
Combustion temperatures could get too hot and you could have problems.
Johnny5ive ОК, Thanks! You can show the standard scheme vacuum hoses?

+Ikthoosdotorg Awesome, thanks!!
would this pass smog/deq?
No. All the parts that you take off - keep them someplace safe 'cause you're gonna need to put it back on to pass Emissions Testing - at least in MY shop!
I have a 4ze1 and the thermal egr valve on top of the thermostat is broken and sucks air like a bitch.ur saying I can delete this.can you please give me some info on that please.cheers.
Yes, you can delete it and the truck will run fine.
