Question about 2000 Mitsubishi Montero Sport
Compressor freezes and crankshaft pully comes off
If you do not use, or do not need, nor intend to use a/c for a while, go to your mechanic and ask to have the a/c pump removed, and install a replacement pully and bypass belt. You can always add a/c back later if you want or need to. Otherwise, like in the previous answer, sounds like the bearings are froze up and this fix will should be cheaper than replacing the a/c pump.

It sounds like the bearings in the compressor are shot. Try to remove the drive belt from the pulley and see if you can spin it by hand. Even if you can there still may be a problem with either the bearings or race. You would probably have to replace the compressor. Good luck

The problem is there is a leak in the 134-a refrigerant system and the level of refrigerant is low so, the low pressure sensor is reading too of a low pressure in turn causeing the low pressure switch to turn the power off leading to the compressor.

Your belt is loose (and it just needs tightening) or it is worn and needs to be replaced. It may look ok but they glaze over; all the little ridges get shinny and slip.

Get the gas pressure checked, if it is low the power is disabled to prevent damage (the gas carries the lube oil so no gas-no oil) you can buy cans and adaptors to top up yourself, the often have the correct oil and a dye to find leaks.

SOURCE: I have a squeaking sound
once the belt become loose it slips and its friction surfaces become damaged .. even if its then tightened properly it may still slip .. an old damaged belt should be replaced and tensioned properly ... its common for older type belts to slip and make noise .. it is not as common in later cars since they often have automatic belt tension and improved belts .. any slipping is a sign of some other problem ... one frequently seen problem on some cars is a pulley that is spring loaded to keep the belt properly tightened .. the pivot on the pulley freezes up and no longer maintains proper tension .. those pulleys can sometimes be re lubed but often are hopelessly frozen and need replaced ... also other pulleys and the alternator bearings can start to make a squeaking noise when the sealed bearings lose there lube .. you can put a drop of oil on each bearing to see if one quiets the sound ..
