A/C compressor valve stems HELP! (1 Viewer)

[fj62max]

I have an HDJ81 and have a small leak that maybe coming from the top. I would like to replace the low and hi side on the compressor. I still you R12. Anyone know the part number or both or know where I can buy them? Thanks

I would look up r12 Schrader valves if that's what you're wanting to replace.

They have kits with different sizes on Amazon and not expensive.

Replacing that particular Schrader valve (assuming it's the same as the FZJ80 model??) was discussed a long time ago but can't find the threads. IIRC @Coolstream user name (Auto AC Tucson Arizona) used to be on the forum and had an auto AC business that sold parts.

As discussed Toyota doesn't offer a replacement Schrader valve for those connections but there should be a size that will fit, fatter than what is found in tires for example (already mentioned above). Might be one of these, pull the old valve out and match it up from a kit (link above):

Link to a long thread on AC repair:

A/C system - how to remove the cooling unit, evaporator, expansion valve

It's summer and some of us are experiencing A/C troubles so I think it's time to do a writeup on how to remove the cooling unit, evaporator and expansion valve out of a '97 80 series. Removal of the cooling unit is very straight forward, plan on about half hour and minimal cursing :D You...
