A/C Expansion Valve

[yoshi5]

where is the A/C Expansion Valve in my 95 3.1 i am going to be changing out the Compressor, Receiver Drier, and the A/C Expansion Valve but have no idea were it is at on my car

[3X00-Modified]

We don't have AC expansion valves... We have Orfice tubes....

Google how GM did its AC systems and it should help you out.

Wrong info....

[yoshi5]

i was just going by autozone parts the due not have a tube listed for my car just http://www.autozone.com/autozone/parts/ ... 25_0_9225_ were is the tube at and were can i by the part ?

Someone else needs to chime in here, I don't ever remember seeing one of those down in the cooling system, but they definately list it for my car too... that's odd.

It's up under the dash next to the evaporator and heater core.

[yoshi5]

is it easy to get 2 ?

[heavywoody]

Depends on if you have everything out (heater core, under dash plastic, dash lol...).

IIRC, it's attached to the evaporator core... if it's the same part I'm talking about.

That's an awkward place to work on stuff regardless.

So we have an expansion valve, or we have an orifice tube? I thought we didn't have the expansion stuff due to how GM did its AC systems, or is that just on the trucks?

Never mind I stand corrected...
We have a V5 Compressor.

I guess I wasn't paying attention enough when I did my heater core to see that up there.

MY BAD...

[yoshi5]

i have to take the heater core out to get to it ?

Well you need to at least take all the plastic out from under there to gain access to the heater core... After that yeah IIRC there is one more plastic separator that the core attaches too that hides the condenser, so if its near that then you probably need the core removed to get that part out to see it.

This is core removed, I'm guessing its hiding behind this plastic cover just like the condenser core is. When I did my heater core, this part was actually NEVER screwed in from GM... the bolt holes didn't even have threads so getting the main cover out was a PITA because this kept dropping down in the way with the core attached to it. I actually had this all out and the Condenser core exposed and I still don't remember seeing that damn valve... Man I totally blanked on that one.
