Top stuff I'll book mark that for when I fit my air con.
What compresser did you get, and what about the bracket?
That is fair wedge for postage.

Its a Monaro/GTO/Commodore unit - this has the fittings on the side.

Corvette has fittings on the end and does not fit.

It looks like 92088081 on the box to me.

I bought the bottom one with the vertical fittings. The idea was that the fittings would face the front of the car.

I think however that they are designed to face the rear of the car. There's a large fitting and a small fitting. When facing the rear, the large is on the bottom, when facing the front the large one is at the top.

On the SB compressors they have the screw on fittings so you cant really go wrong. This fitting I have can go either way, so my question is, which port in the compressor is the return.


The top fitting on the compressor has a filter in it. I am assuming this is there so that if the compressor packs it in it doesnt ruin the rest of the system. I am assuming that this is the outlet of the compressor and should have the smaller hose attached.


I am assuming that the large hose is the return - my thinking is that the larger hose is because the gas has expanded.

Am I correct? If so, I am going to have to cut the fittings off and swap sides as the fitting is indeed designed to face the rear. The one with the horizontal fittings would not have this problem, but the hoses are not long enough to do it that way anyway, and theres no way Im taking the side pod off to change them.

Logic says the small is compressed and the large expanded.

Can you not buy right angle adaptors to make the hoses point the way you want?

The adaptors are made for common installations i.e.front engined cars, its only when you want the AC hoses pointing towards the front that its a problem, and that wouldnt be the case on front engined cars.

Can anyone confirm if the port with the mesh in it is the outlet?

[crafty]

Bump.

I think the hose size assumption is correct, small hose compressed side, large hose expanded side.

Can anyone confirm if the port with the mesh in it is the outlet of the compressor?

Crafty,

Two of my work mates in Melbourne have fair dinkum Australian Monaro’s, one green and the other black. Both 5.7 litre LS1 V8’s. I will see if I can have a look under the bonnet of the black one for you tomorrow

Problem solved.

I reverted back to the Vette AC compressor (with the fittings on the rear of the casing) and used the fitting below..
