Hello all you cool cats, global warming is back in my neck of the woods and my 99 XJR is cooling but not as well as I remember.
I was planning to try a quick recharge with sealant built in but when I looked under the hood I seem to be missing the AC info sticker.
I would expect that the old girl uses 134a refer fluid but wanted to check here first.

 

welp, the AC Pro site had a nice "AC Specs" tab that went quite a ways back (well beyond 1999) that says my XJR wants 24 oz of R134a refrigerant.
I'll do a manual edit to my owner's manual for reference in the future.
Thanks.

 

I suspect the system may have had some residual 134a in the system. It is good to bring the
low side up to a least 40 psi and see how the system responds.

 

Buy the AC Pro set at your local supply store and follow the directions. Don't overfill it.
