How do you tell Factory air from Dealer air? The Carparts.com has expansion valves and they have one for Factory air and another for Dealer air. I have a Sanden compressor if it helps. 87 turboii. Thank you.

 

i am curious to know also. i am getting ready to overhaul my a/c system. i have an 87 n/a but my a/c came from a 91 turbo. sorry i couldn't be of more help hailers.

 

factory air uses a mazda compressor, dealer air dont. im pretty sure anyway

 

the receiver/drier canister is different. or I should say the bracket that holds it on is different. on factory AC it's a separate piece. on dealer AC the bracket is built in.

it may be that the sanden compressor is dealer, but i can't garauntee that. i know my 86gxl has a sanden, but my 10thae has a nippondenso.

 

From the current posts in this thread it seems I'm wrong, but I've been told (a long time ago) that all A/C was dealer installed.

 

No such thing...
