Hi all: I'm new to this forum and my Jeep, but not new to repairs of this vintage and older (1988)
I just got a 1988 Comanche 6 cyl. 130,000 miles. Body rust issues, but not too bad. Engine and power train look well maintained, lots of power. Seems to run fine. Burns a little oil (maybe 1/3 quart on 65 mile trip).
On its maiden voyage, a clattering appeared. It seems to be coming from the A/C Compressor pully or idler pulley. Engine performance hasn't changed.
I tried disconnecting the wire lead to the clutch, but that didn't do it. No surprise, the compressor shouldn't have been engaged anyway. The A/C hasn't worked in some time, according to previous owner, so the compressor may have run out of lubrication?
The last car I had was a '96 Dodge Stratus, and its A/C compressor seized and shredded the belt. I repaired it by trying a few different shorter serpentine belts to find one that would work with the A/C compressor out of the loop. That worked perfectly.
Is this a similar situation, or does the clattering even when the clutch is disconnected a more ominous sign?
PS. Any recommendations about where to get FSM or other useful manuals welcome!
