Upgrading 1987 R10 A/C to R134a parts / questions
I'm looking at having to buy A/C manifold gauges that work with R12 to check the current system. Also looking at the price it's not going to be cheap to recharge the compressor. Looking at some other threads there is a lot of recommendations to switch to the Sanden compressors. I'm pretty... -

Well this was some great advice. Tested the line down to the blower motor was receiving 12v, grabbed a new blower motor for $40 at AutoZone and we've got air (not cold yet, but it is a great start :)) Will continue on to the compressor now and see if we can bring this old thing back to life... -

Also FWIW I tried to do a search on the forums for previous threads but ended up just getting all of the recent posts not really narrowed down to R10 so apologies if this has been asked 100 times. -
Upgrading 1987 R10 A/C to R134a parts / questions
Hey everyone. I have a 1987 R10 with a 305 that I just picked up and am looking to diagnose the A/C issues and upgrade what is needed. I verified that the fitting on it is still R12. The A/C nor heat blows at the moment but after reading some threads on here my plan is to - 1. Open the...
