A/C Compressor Clutch
- Thread starter Jfrost
- Start date
youll unbolt it from the motor and let it hang/sit on a 1x4/screwdriver set across the subframe (dont set it on top of the aluminum trans cooler/return lines if you have em....unless you wanna replace em)
13mm nut holds the plate to the shaft, rent a ac clutch removal tool, thread it in the hub (its sorta an NPT thread) then tighten the center to remove the clutch,
youll have a 50/50 shot if you vent refrigerant...if you do the primary seals are shot, if you hurry at most youll just need to recharge a little, even if it empties it will still boil out for an hour, so you have that long before youll need to worry about moisture intrusion and subsequent drawdown of the system to full vac to remove the moisture.
once the disc is off, youll remove a snapring and slide the bearing/pulley off
behind it is the magnet, try not to damage it removing the pulley/bearing...if you have to replace it its not too expensive.

Have you considered writing a series of 3800 memoirs?
Completely agree. The two months it sat caused a whole slew of issues. Cars are like women, if you ignore them they'll have a breakdown, literally.
Is the rattle when the clutch is disengaged? And goes away when engaged?
I had this probelm on a 1998 Malibu 3100 V6. The pressure plate wasn't fully backing away when disengaged and would rub against the spinning clutch pulley. On a Ford, you can just unbolt it, put some shims (washers) behind it and it good to go. On a GM, you need to us a pressure plate puller. Don't remove the plate, just back it off a touch. This can be done without remove the compressor.
I rented the tool at Autozone. It looks like this, but I needed the complete tool kit as mine was an odd size.

Cant beat getting it replaced and recharged the right way for $50. Thats smart.

Yeah, it does go away once the clutch is engaged. However last time I started the car, after it sat for a few months, the rattle persisted once the clutch engaged. I'll try your method first and see how it goes.
