AC Compressor GVR4 vs DSM

Tried searching but couldn't find anything for sure. Is the AC Compressor from a 1G DSM the same as the one for a GVR4? My compressor seems to have taken a crap, and looking for a new one.
 

I wish I could help, But I'm jealous you have AC.. /ubbthreads/images/graemlins/smile.gif

They are not the same, and the mount is different as well. Not sure if a 1g version could be made to work in the car though. I believe the hose attachements are different.

The compressor on the galant is actually quite common and used in a bunch of vehicles. The DSM's are not the same compressor as Iceman said.

You have to be careful of a couple of things if you consider a compatible compressor from a different car however:

One is that some compressors do not have the low-side charge port on the actual compressor, but rather on the low-side pipe. I got one of those and had to have an R-12 aluminum bung welded near the elbow in the low side pipe (Truck AC shop did it cheap). Much better to make sure you get a compressor with the charge port.

Two is that you may have to change the bell pulley attached to the clutch to accommodate the grooved pulley (6-6mm or 8mm bolts, real easy).
 

I just ran into this problem. I put a engine out of a DSM in #435 and realized the holes in the compressor where the lines bolt up to are different. I pulled it off and put on the galant compressor on the DSM ac bracket which was PIA and only 2 bolts will go in. Then realized the belt wouldn't work it was too short. I ended pulling off the DSM ac bracket, DSM compressor, and the DSM tensioner assembly and replacing it all with the galant stuff. After doing my recent engine swap I learned alot of stuff on the VR4 is "VR4 Specific".... /ubbthreads/images/graemlins/banghead.gif

I installed the engine from a 90 GS-T in 195 and must have switched up the AC brackets. When we finally went to install the compressor (which had been riding on the K-member for a few months - nowhere to go), we could only find the one bracket. They look deceptively similar.

We got the bracket on the block and the compressor in the bracket, but then it wouldn't match up to the tensioner arm or whatever. Since we had no other spare, we took one of those Ebay strut tower bars some DSMer left in the shop, cut a 2" section out of it, countersunk bolt holes and then bolted it to the bracket, before bolting the tensioner to the adapter we made.

Just as well. I'm pulling the AC out of 195 to put into 464 and aw sh*t. I bet that's still the only f***ing bracket I've got, too. /ubbthreads/images/graemlins/banghead.gif
