Re: A/C Oil Drain Plug

That plug was the high pressure relief valve. It needs to be there, or a high pressure event could shatter the compressor case. Given that it was overtightened & broken, the pieces dug out - and then replaced with the wrong thread pitch? It is very likely that the sealing surface and/ or threads...

Re: Replace Pressure Relief Valve?

It is unlikely the control valve has anything to do with the hose manifold leaking. The seals at the hose manifold sometimes fail. On a 20 year old car it is likely that connection has been open at least once. I would clean up the leak area carefully & watch to see exactly where the leak starts ...

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...
