I bought this 88 Cherokee last winter and now that summer is here I want to use the a/c, but of course being that old it needs recharging. A co-worker suggested getting a DIY kit - but I’m concerned now (after purchase! of course) that DIY may turn into SIUY (screw it up yourself).
1- I can’t definitively pin down where the low-side service port is (4L flat 6, btw). Pretty sure that it’s on the firewall but cannot locate. A few web links suggest it has an "L’ on it - dur, can’t see it.
2- This old a car must have been using Freon, everything now is the more environmentally friendly R-134A for replacement. Am I going to have to do any conversion before this recharge?
Seriously considering returning this DIY kit and having my local auto shop graybeard take care of it for me. What do you think?
