I have an 87 300 TDT and yesterday I removed the compressor to repair a clutch bearing (not easy to get out) Anyways turns out it was the comp. squealing and not the clutch. It must have failed and locked on so the comp was turning all the time. I took it apart and removed the magnet and key from the shaft and reinstalled. (the clutch was also cooked) It works fine now with no noise. My question is, Denzo makes AC Comp for all different makes and models. Are they not virtually the same except for mounting? Would a compressor from a 300E not fit my 300 TDT wagon? What would be different? They look identical.
