Does anyone know the part number for the hose from the throttle body to the AC idle up actuator, circled in red below:




I believe it's this one in the parts diagram, but there's no number for it:

 

This says it fits.
Looks like the correct shape/bends
Has a part number listed as #1985-1988) 22233-35010 - IAC Hose
Good price for a formed hose.

 

The hose from the throttle body to the AC/power steering idle-up valve is just a piece of plain bulk hose.
I bought a piece of suitably sized silicone hose to replace mine.
The molded hose JoeS points to is a completely different, and larger diameter hose that is found under the intake plenum on the other side of the head.
That molded hose goes from the throttle body to the actual IAC valve on early 22re engines.
Later 22re's have a different design IAC setup that does not use this hose at all.

 

Thank you, unfortunately that's a different hose, it's the one going to the IAC as shown below. I already replaced that one, so the part number looked familiar. I need the one that is going to the AC idle up actuator.

 

Thanks @millball . My truck came to me with a plain section of aftermarket hose for that connection, but then I got a used OEM hose from a buddy and it is definitely molded (see below). I'd like to get a new factory hose just to be authentic, but I can't for the life of me find this hose on a parts diagram.

 

I don't think that is a molded hose.
Just age crustified into that shape.

 

That's certainly possible, I have noting else to go by. Just really odd that I can't find a part number on any diagram.

 

Well I finally found it, it was on the AC vacuum piping diagram below, callout 88689. It was originally PN 88689-35010, replaced by 88689-20390. Both are discontinued.

 

Bummer nothing worse than the big D word popping up….this thread does remind me I need to replace some hoses including this one….

I read that wrong. Sorry. It sure looks the same shape and length as the one going from my idle up large bung to intake manifold.

Mine is molded on my 86. A basic 90 degree bend tube cut to fit would look close to factory.

Don't think that hose (number) hooks-up to the large rear bung to intake manifold. Follow the dotted line. It appears goes to a small side bung.

 

No worries, the two hoses do look similar. Thanks for confirming that yours is molded; the one I got from my buddy is also molded.

But I think that hose in the diagram is the correct one, compare it to the actuator in the photo below. If you look down at the actuator, such that the port that threads into the manifold is at 12 o'clock, then the bung in question is at 9 o'clock, both in the photo and the diagram.

 

My hose does not have a double bend as the one in the diagram. The one in the picture is also straight on that end. Still think it's not the right hose. Hey, I have been wrong before- See above, LOL. Mine has a cracked end at the manifold and I'll soon be replacing it with a standard 90 degree, cut to fit. Close enough for a 37 year old truck.

 

That part I do agree with - the hose in the picture seems to show a double bend, which is not right. But if you look at the associated PN on the TPD web site, the cartoon appears to be correct. Doesn't really matter, since it's discontinued .
