Friend has a 91 Taurus. A/c stopped working a few years ago. Put the gages to it and it has about 43 psi. Noticed the clutch gap was way over .100 thousand, but tight to get at while mounted on the car. Is the clutch assessable through the fender well? Sure would make things easier! From reading the posts on these cars it's an easy fix once you have access to it. Thanks for any help.
While that is a large gap, and it needs to be tightened, 43psi of static pressure is definitely a sign of an undercharged system. You will need to pull the compressor off of the block but may be able to leave the lines attached to adjust the gap. You will want to check for leaks though and have the system evacuated and recharged with the proper amount of R12. Depending on ambient air temperature, your static pressure should be more than double what it is now.
Should check the hub to learn if it has real springs or the bent rubber kind, latter is crazy as that rubber gets as hard as a rock and breaks. Having any kind of a positive pressure is great news or the system can be rotted out on the inside. But no telling the condition since it hasn't been used for years. Good luck.
Hi Folks; Thanks for the replies. The system will be checked out soon, and from what I gather reading through the posts, if you have to struggle to take it off to repair it, just replace the compressor with a new unit. I'm hoping that at least with the static pressure I'm showing, there might be hope the evaporator is OK. We will not pursue it further if that is shot. Yanking the dash apart to fix it is out of the question. Thanks again!
Can't forget about the spring lock couplers used in these vehicles, a couple of very dried up O'rings between two pieces of tubing, really not easy to replace.
Hi NickD, That's one of the things I noticed on this car, and I talked my friend into taking it to an A/C only shop a few miles away to go over the system. Thanks for all the help!
