You guys are making a big deal out of nothing. Replacing the compressor is easy, you just have to follow the instructions. Buy the Ford Service CD or DVD, and follow the instructions exactly using the tools that the instructions tell you to.
Compressors do not seize without a reason. Ac
compressors are not magical creatures or women.
Torque fasteners as instructed, to the proper torque.
Too many peoiple taking things aparts and put them together incorrectly, BECAUSE THEY ARE TOO CHEAP TO BUY THE MANUAL, OR TOO IGNORANT TO FOLLOW INSTRUCTIONS.
Don't blame the car if you screwed up.
That being said, most ac
clutch seizures are caused by bad ac
clutch pulley bearing. When you don't replace the ac
clutch pulley when it starts to fail and it wobbles, it will hit the ac
clutch coil, and eventually jam against it, seizing the pulley and breaking or throwing the serpentine belt.
At this point, you either must replace the entire clutch set (magnetic plate, ac
clutch pulley, and ac
clutch coil) or the complete ac
compressor with ac
clutch set. Even it you buy a complete compressor, you still need to check and set the magnetic plate clearance, regardless of what the Parts Guy or the instructions say.
You will need a torque wrench with the correct range, normal mechanics tools, feeler gauges, snap ring pliers, serpentine belt tool, and a tool (AutoZone Free Tool Loan Program) to hold the magnetic plate so you can loosen the center bolt on the ac
compressor. After installing the compressor, you will need a vacuum pump to evacuate the ac
system (can borrow from AutoZone Free Tool Loan Program). and to refill the system with refrigerant you will need a set of ac
manifold guages. I recommend that you buy your own set (about $44 from Harbor Freight).
