Re: Stuck Compressor Clutch Plate: Suggestions on Removal

So what was the resistance of the removed coil?

Re: Pressure Relief Valve?

In theory, the HPRV should re-seat after opening. Sometimes they do not. If you have a valve that fits, but the threaded portion is bottoming out before the O ring seals you can probably trim the threads to the length of the part it is replacing. The site sponsor should have the right one available....

Re: AC accumulator draining too fast, high hi side

Yeah Ice it is a TRSA12B - still say there is an H missing there someplace...

Feathers? I guess Texans pluck chickens in their rigs. Mostly I see dog hair in evaporators around here.

Re: Stuck Compressor Clutch Plate: Suggestions on Removal

Nice work around on a unit with no puller access. Glad to see you got it fixed

A lot of labor however.
Commercial shops would replace the compressor in less time than it took to drill the rivets & modify the puller.

Re: Fog and refrigerant blown out of vents during recharge

Nitrogen is the industry standard. Normally supplied from a high pressure tank with a regulator. 134a can be used to pressurize a system for leak testing, but if you have a big leak a single can may not last long enough to locate it. That is why we use nitrogen in a shop. Soapy water works, but the ...

Re: Adding UV leak detector question.

And the ol' jumper wire kills another compressor!

The low pressure switch keeps the compressor from running when there is not enough refrigerant in the system to circulate oil.

Your compressor is done. The condenser is now contaminated with debris from the compressor.

Re: 2014 Land Cruiser AC Problem

Please STOP telling people to jam solid objects in to accessory drives on running engines. I have see what happens when a screwdriver was used to "tap" a clutch - took out a radiator and the hood. Could have killed the guy that tried it. Check & adjust the clutch gap. No need to do dan...

Re: Fog and refrigerant blown out of vents during recharge

Yes, the evaporator is done. Unless you blew a heater core at exactly the same time as you were charging... System open to the elements for 6 years takes a toll on parts. Internal corrosion from years of atmospheric humidity. A leak that won't hold 10" vacuum? Yeah, don't bother trying to charg...

Re: AC accumulator draining too fast, high hi side

It is doubtful the evaporator is the issue. To diagnose it correctly you need to charge the correct weight in to the system. You can't determine the charge level by pressure. We also need temperatures to relate to the pressures. If your ambient temperature is 72f, 315 on the high side is bad indeed....

Re: Don't know how much oil I lost

Your title really says it all. Precision guesswork is gambling. Add just enough oil, and things will work out. Add too much, and you will be flushing excessive oil. Add too little and you will be flushing bits of ground up compressor. In your case, the leak happened all at once, while you were prese...
