Re: Sourcing R12 240sx compressor


Your condenser might be appropriately sized as well.

In my car, I believe that Toyota used a serpentine condenser and R/D left over from their R-12 vehicles, and they cooled just fine for more than 29 years using R-134a.


Yeah in my experience a lot of the Toyota cars had rather large ...

Re: Sourcing R12 240sx compressor



Without also swapping the serpentine style condenser for a parallel flow, i would be sacrificing quite a bit of capacity and efficiency from what I’ve read.
Not necessarily.

For what it's worth, until recently, I owned a 1994 Toyota Camry V6 Wagon, bought new, with a factory R-134a system ...

Re: Sourcing R12 240sx compressor

We installed a compressor that was for a 1998 maxima (I think). Drained the pag46 and swapped in ~7oz of mineral oil. Also flushed condenser, installed new evaporator coil (dry), and another new drier.

We bought a new TXV but it didn't fit so we had to reuse the original. It had particulates in it ...

Re: Sourcing R12 240sx compressor


As for this issue, no one makes compressors anymore. If the core is good, it turns internally. We can have the compressor shop rebuild the customer's core. Same as buying the reman on our website, plus the freight to send it to our compressor shop.

Hey Tim, how can i get more information about ...

Sourcing R12 240sx compressor

Hey guys, trying to help a friend with his 92 Nissan 240sx hatch. Replaced the drier and vacuumed and charged by weight with r12, but compressor doesn’t compress. I’m having a problem sourcing any type of replacement compressor. I’ve checked rock auto as well as our ACkits.com link but to no avail ...

Re: CLUTCHED compressor shear pin?

Hey guys, so I have the old compressor out. Oil looks healthy, no metal. But upon trying to weigh the old compressor oil (I KNOW I should have used volume instead of weight :oops: ), I was only able to get roughly .8oz out. I'm sure if I tried long enough I could get closer to 1oz out, but I was ...

Re: CLUTCHED compressor shear pin?

Okay, answered my own question. I removed the fender liner so I could stare directly at the compressor. There's a rubber dampener between the compressor shaft and the outer portion of the clutch. That dampener has broken free from the compressor shaft. So even though the compressor clutch is ...

Re: CLUTCHED compressor shear pin?

Oh, and the thought of a slipping clutch did cross my mind as well. As did a stuck open metering device, but I cannot see that allowing zero pressure differential.

CLUTCHED compressor shear pin?

2013 Mazda CX-9 3.7 with rear AC, 203,000 miles.

Greetings, looking for some insight on a friends 2013 Mazda CX-9. When AC button is pushed, I can watch the compressor clutch engage, fans kick on, but absolutely no pressure change occurs on the gauges.

I have dealt with clutchless AC systems ...

BTW with the usage you describe, if there is a cabin air filter, I'll bet it is clogged with dog hair
No cabin filter on this one, I think it was just constantly recirculating dog hair :lol: Airflow from vents is plenty sufficient thankfully.
