This video is exactly what I needed. My mechanic informed me that the IAC on my 2002 was leaking and I had no idea where it was or how to get it out until I found this-thank you!

[@FixingWithPassion]

Great!!

[@Cameron_Baillie]

@@FixingWithPassion Do you know if you need to remove the entire throttle body assembly in order to remove the solenoid or can I just leave the entire assembly in place and remove the solenoid if I take the tension off of the spring? :)

[@davidschick7269]

@@FixingWithPassionthanks for the video what’s the part number?

[@brother_dana]

I have this exact leak, or at least so I was told by the mechanic. But it's leaking much more slowly; I lose about an inch of coolant in the reservoir every 1K miles or so. So, I've put off fixing it. I've saved this video for whenever I get around to it. And thanks for showing the process of reattaching the throttle body. Greetings from Virginia.

[@vonkug]

That leak is right above the exhaust, you'll lnow when it goes. The steam alone will blind ya

Hello from KY. One day all of a sudden my Xterra’s temperature gauge started climbing. Turns out I was low on coolant. So I did a pressure test on it and found coolant residue and fresh coolant very very slowly leaking out this part. It’s covered in green. Thanks for the video so I can see what I need to do.

[@FixingWithPassion]

O my! Just in time for winter!!

[@emartinez6584]

Thank God I found your video , before taking of my upper plenum like all other video`s show , for the exact same leak . , THANK YOU and Happy New Year .

Thanks from Nevada... My '02 Frontier with the VG33E has a leak at the throttle body, a leak at the power steering reservoir, and a rear main seal leak lol

Dealing with this exact problem for a female friend. She let it get a little low and it shut down. Thank God she didn't try to do anything else. I replaced the thermostat, water pump (what a task..wow), radiator and flushed and refilled. Charged it cranked it then found that beginning issue. That is for this video

Nice!

[@ryanspenard3750]

Thanks Nathan! I recently swapped out my spark plugs and upper bank O2 sensors (with a great deal of help from your videos by the way) My X is idling a bit rough but accelerates and drives at speed nicely. I'm going to pull the throttle body to clean the butterfly valve and your video has given me excellent information to properly tackle this job. Thanks so much!

[@mattandkatchristie2552]

What was your issue?? I'm having same problem idles rough but if I give it gas it's perfect.

[@jimbosavage]

I'm sure this is the problem with my vehicle. Thanks for the info making it easier to do the job.

[@ralphanthony5198]

Man, thank you for making this video. Well explained. I have a similar issue, but what's leaking is my hose, I'll have to replace it. But what does exactly that valve does? What is it good for? Will check out your other videos. Thanks again!

Thanks just what I needed today..same problem in my 2000 Nissan frontier SE.question what size hoses are those

[@thesetruths1404]

Hey there i have a 3.3L 1998 Pathfinder, 174,000 miles, and my setup looks identical for the thermo-element. Question though, somehow mine is leaking motor oil from around that thermo-element seal location, very slowly, about 8 to 10 drops per hour of operation. Can oil access that thermo-element to do that? I am scratching my head. Using my finger i can wipe oil saturation the mating location where the thermo-element seats onto the throttle body. It is not coolant. I am sure. It's also losing oil slowly from checking dipstick, and i don't have any other leaks. I'm scratching my head about this! 😮

[@menehuneben]

It's a long shot on timing but... what size are those hoses off the Throttle? That short hose tore.

Tks, very helpful!!! Brownsville Texas.

Thanks for that video, my rpm keeps riding rough everyone tells me different things I believe it's the IAC Valve what do you think?

[@venomx4093]

Get a good scanner and see what the % is on the iac at idle. My iac is totally dead, but it still runs lol. A cheap scanner will show an iac code if it's bad. No code, then look at other possibilities like a dirty MAF sensor, bad TPS sensor.

[@bernainmolina7481]

Question for ya im assuming the coolant needs to be drained to do this job and does the gasket maker on the O-ring necessary just cuz in case it can clog or cause an issue later.

[@FixingWithPassion]

Not really if your fast or can temporary plug the hole. Just drain some.

[@xterraoverland4380]

Fixed mine today. Thanks

[@Zugeily1981]

@XTERRA OVERLAND Did you experience any issues with rpms and surging idle after fixing it?

I have a 2004 xterra and when I put a new intake gasket i bend the plate where the screw hits that sensor and after that I had a high idle,when cold it was 1,500 and it will drop to 1,100 so I bend that bracket that way it wont touch the sensor and now 1,000-900 cold and 750 when hot,I dont know why but this is what that sensor suppose to do but on my truck it seems like it dont need it😂

[@FixingWithPassion]

Yea there a pain.

[@gregorysorce1898]

Can you do this repair without removing the throttle body? I ask because the hoses attached are "glued" on after so many years, and the only way to replace the hoses is to remove the plenum which is a job of it's own. I'd rather just leave the throttle body on if I can.

[@jimbob7978]

Did you find an answer? I was thinking about trying the same thing.

[@gregorysorce1898]

I did not find an answer. Got rid of the Xterra before I could do the job.

Just got an 03 3.3 that’s idling a little rough. Read the codes and got an egr code. Any information? Replace the valve?

[@mattandkatchristie2552]

Mine idles rough as well. How'd you fix your issue?

[@scottyfixer452]

Hello from Cincinnati Ohio. My arm that makes contact with that thermal plunger looks bent almost like the plunger pushed it as if the spring was stuck causing the arm with the screw to bend. It’s an 02 how did yours look

[@FixingWithPassion]

Same way...I guess it was made on Friday at 4:59pm...lol They all seem that way.

[@scottyfixer452]

@@FixingWithPassion looked at a factory one and it’s supposed to be at a 90 this lets the idle drop to the mark on the throttle. After I bent mine back it idles low where it was supposed to be when the thermal plunger got to temp. After this I redid my base timing and it is like a brand new vehicle

Do you know what size the pcv hose is? Also the hose next to that which is a slightly small heater hose?

[@ODADDY25]

Hi. Did you find that the small pin that comes into contact with the thermal unit was bent? Mine seems to be bent and almost sliding off the edge of its contact point on the thermal unit. I was wondering if it will come back into alignment one the element starts moving properly again or if I have to bend it back into place? Thanks.

[@scottyfixer452]

Mine looks bent as well. Did you bend your back

[@scottyfixer452]

Mine was bent. I bent it back to a 90 degree bend . Started the cold engine and watched the plunger arm push the idle cam until it got to temp. There are two marks on the idle cam one for hot and one for cold. They plunger should push that cam to the hot mark if it’s adjusted or bent to the right position. After I let it warm up I reset my base timing to 10btdc and it runs so good smooth idle great acceleration

[@tammycast9640]

Well that's not my promo My leak is the rubber hose

Small brush and WD40

[@BrandonLyons1]

Do you think you could delete this part? Im always a fan of deleting things that i can

[@FixingWithPassion]

If you can i'd check around.

[@BrandonLyons1]

At the very least i think im reroute the piping. All my hoses are crap and i like making things more modular

[@bikerboysrus1]

All it does is run high idle till the vehicle warms up then the pressure pushes it out a certain amount to lower idle as your engine is heat soaked. That's why the screw is there, it extends the exact same amount at proper temp every time so you can fine tune your idle. To delete it just plumb the intake hose into the return hose. If you delete it I would suggest you let the truck warm up properly every time below 50°

[@bikerboysrus1]

To be fair you should always let it get idle up to temp ...just more important up north....don't mind my rambling 😊

[@crp9985]

I couldn't get that thing out for the life of me. Whatever you call it, the brass valve.

[@FixingWithPassion]

Yea its a PITA!!

[@ODADDY25]

He said that it slid right out? No it does not!

[@bluegill2030]

Does this part control the surging idle when the engine is hot as well? What other parts could cause this??

I'm having rough idle at low rpm idles up n down a bit. What was your issue??

[@bluegill2030]

@@mattandkatchristie2552 in his video at 9:27 (just to the left side of his pliers), see the 2 metal tubes (one big and one small). The little one on the right side is a vacuum port (the small one). Follow it under the intake and there should be a rubber hose attached to another small tube (Hard to see but it’s there), As soon as I hooked it back up the Engine was ROCK SOLID!! Not a hiccup at all still to this day, thing runs absolutely perfect and is so smooth it’s ridiculous!!!! 😊
