I pulled the valve on the right out of my low-side port. The replacement in my FJC assortment is the one on the left. Is it compatible with what I took out?


I contacted FJC customer support.

They said

So, the one on the left is the correct part which is 2676 and the one on the right that ...

So I bought the FJC 2663 assortment which is normally $50 from JB Tools via Amazon. But they had one that had been returned. Normally, I don't do this, but the price was < $15 including shipping! So I took a chance... a couple of late-model GM cores were missing but everything else is there and ...

My system is empty at the moment and I'd like to replace the R134a Schraeder valves as a precaution. I see a bunch of sets on Amazon, but would happily order elsewhere or even better at my local NAPA if someone has a recommendation on what to buy.

Thank you all! I am assuming the hoses need to be connected before I rotate the compressor to distribute the oil (it has caps on the outlets at the moment).

Ya know, for some reason, I am just now seeing this question and pic.
Of course, an AC line being close to exhaust equipment will most assuredly increase the hi side pressure. Or low side pressure.
INSULATE now. We would usually use fiberglass based exhaust wrap, it comes in rolls….have at it ...

I had the system evacuated at a shop ($56... very ...

THANK YOU!

If I take my car to a shop with one of those fancy Sun machines for AC service, how much should I expect to pay to have the R134a recovered?

Will the machine be able to tell how much got pulled out?

When I recharge the system, will I have to add any oil?

I am planning to do some hose alterations ...

275 hi at 92F is overcharged.
Your vent temp is not where you want because of too small a condenser, as we have mentioned.
Not sure why you think you have a leak.
I have stated many times, bite the bullet and get a sniffer, they are so quick and easy to detect leaks, and I think more accurate ...
