Has anyone ever removed the two phillips screws that hold on the 2 coolant inlet/outlet pipes?
I got an IACV from the junkyard and I don't want the rusty pipes touching my cooling system, so I want to change the piping on my original IACV to this one. These are either rusted on, or I just can't remove them. I am using a JIS #P2 screwdriver. Are those phillips #P3?

 

Not ITR, but I found this in 5 seconds...



If you open it up, make sure you can get it to seal up again. The gasket will probably be quite shot, and non-replaceable.

 

im sure its been that way for over a decade easy..



i think they hop on here thinking those guys with itR's seem to know their ****, i wont even ask anyone else..

 

I still can't seem to get it off. I have no idea if there is a gasket underneath the 96-01 Integra one (it's not ITR specific), but it would not be good thing if I get it off and the gasket is shot.

 

Just take the screws off and the cover usually falls off, if not grab vise grips. I've been through 3 of them this month and they all have the same design.

Also interesting to note that the non-VTEC IACV have a smaller return port going into the manifold. Not sure if this is causing the issues for me with a much higher flowing motor... but I am having issues with the IACV falling back on base idle on deceleration. Hondata has a duty cycle adjustment on the IACV and I'm wondering if it needs to be increased due to the smaller port to keep up.

 

That is interesting, but I am not sure. Why don't you have the VTEC IACV?

Also, what is the best way to get the screws off? I have tried and they are very tight, I am about to strip them. I am using a P2 screwdriver from Vessel (JIS) so it is pretty much one of the best screwdrivers. Are these screws P3 size?

 

I don't have the VTEC one because the majority of people I know with Honda motors are unfortunately B20's lol. Get a long handle screw driver and push hard into them while turning. Or put a small vise grip on the head of the screw and turn that while turning the screw driver.

 

take your good screw driver bit and toss it into a 1/4" socket on a 1/4" ratchet. That will allow you to put a ton more torque into the screw before stripping it.

 

That is a good idea. I decided to just sand the metal as much as I could, and install it as is. I doubt it will affect my cooling system as much as I thought. Unfortunately, this IACV did not fix my idle issue so I guess it was never my IACV to begin with.
