1991 Q45A Compressor Replacement

[mwd123456]

I have a 1991 Q45A with 155,000 miles on it. "I love the car" the A/C compressor is making noise "bad". I have a compressor to replace the bad one 'good'. Only problem is i cannot extract the fourth bolt. Bottom two are easy, the third one in the front is hard to get but with some patience i extracted that one. Now the fourth is in the back and i cannot even see it from the bottom or the top of the engine. "Any suggestions"?

[3rd Q]

That one is a b***ch to get to. I used a 3/8 adjustable head ratchet with an extendable shaft (Home Depot) to get to it. The angled head helps you get the socket on it, but there is not much room for you to move the ratchet back and forth. Time and patience required. BTW, removing is the easy part, re-installing is more difficult. Thread in the other 3 bolts, do not tighten since you may need to move the compressor around a little to make sure bolt #4 catches the threads.

Good luck,Paul
