Re: 91 Volvo 240 manifold gauge question

Hi Durk, I recognize your name from the turbobricks forums. Little something I've noticed with the volvos, we don't have a high side pressure port! We simply have a low pressure port, usually located on/near the receiver drier. I believe that many of the cars had the port on the back of the compress...

Sourcing Quality Compressor

1990 Volvo 740GL, NA, auto, SOHC, originally r12 car. Hey guys, not sure if this is the appropriate subforum for this topic but if not, please move it accordingly. My fiancés ac compressor is leaking oil/refrigerant from what seems to be the front and rear of her compressor. Rather than pulling it ...

Re: Toyota pickup AC questions

Do you know for sure that it was low on refrigerant? I ask because it's not possible to tell how much is in it by pressures alone. Recovering the charge and weighing it is the only way to gauge the actual amount. I guess I do not know for sure based off of pressures. I had just assumed that the low...

Re: Toyota pickup AC questions

I just let the mechanical fan disengage and then turned off my pusher fan and high side pressures are only around 250psi or so. Low side 40psi. Perhaps it just needed time to equalize while filling.

Re: Toyota pickup AC questions

Got a text from the neighbor stating that her ac had quit working. I planned on coming home today so conveniently, I was able to take a look. Rented the equipment and checked pressures. It was low on refrigerant as expected, but not low enough to not kick on the compressor. Not sure where the leak i...

Re: Toyota pickup AC questions

John, thank you again for the reply.

I have yet to find a R/D that says it's r134a compatible, but will continue looking. It is actually quite difficult replacing this with the grill on the truck, so I may have to remove it again..time will tell!

Re: Toyota pickup AC questions

I think that some people rent those pumps from AutoZone, use them improperly (causing oil to spill) and then they run them while low or out of oil. This obviously causes irreparable damage to the pump. Last year, I was 100 miles from my own vacuum pump. I got the free loaner vacuum pump from local ...

Re: Toyota pickup AC questions

Thanks John. I texted my neighbor this morning and she said the AC still in fact is working, although still not as cold as it should be. I want to assume the system is now reliable (even if I’m a hair low on oil... :oops: ) I have been 2 hours away at school for the past few weeks so I haven’t touch...
