sanden help

does anyone know what cars came with sanden AC pumps and will any sanden work or does it have to be the 708

and the same for york??????????

Theres a list of compressors there. The 508 will prolly work also. Not really sure.

I run the 5 series....the only thing it HAS TO BE is R-12, R134a will not work as they are not an oil bathed compressor.

I run the 509 I think, I have used it for 2 years at 175 psi, and the only thing I do is check the oil once a week, and fill it when its down.

is there any Way of telling if its a R-12, R134a by looking at it

The stickers on the compressors should tell you what kind they are

And the R12 will have a small bolt on top to fill the oil bath, the 134a will not.

do those engine driven compressors burn a bit of oil? or leak?

Mine blows by like 1/4 pint a week when I use it hard....but it is a stock compressor from 1978, so eh a little leakage is to be expected.

i ran a bunch of sandens on my s10 before i got the mazda. i had the best luck with the 508s, which is what comes stock on mazdas. the only real difference in which compressors came on which cars is that some have a different backing plate configuration, which means that u might have to change some fittings. worst case scenario what i did if i got one that had a different plate was pull the plate off of my blown up one and use the plate off of it. takes like 10 minutes. i got most of them out of junkyards on jeeps. theyre badass little compressors, nothin like watching your tank gauge move. cant do that with an electric. only reason i blew them up is i would forget they were on and run em forever and build like 400psi or something ridiculous. once they get hot they are pretty well toast, the oil loses viscosity and therefore the compressor loses lubrication and its shot after that. you can prevent this by running a thermal shutoff, but i never did that. wouldnt be a bad idea if you had a new compressor or didnt have a junkyard close by. make sure to have a check valve on the tank too incase the compressor blows up you dont air out on the side of the road. and run a GOOD water trap, the metal cans only high pressure (250+) will blow those crappy plastic ones to bits.

does the sanden have a built in check valve like the yorks?
