I have a 1997 plymouth vouager,3.0 v6 . The belt that goes around the alternater is loose and squels . How do I tighten it up ? There are two belts .One goes around the air conditioner , I have already tightened it up ,but I have not figered how to tightened the other belt . Help please.
Did you just purchase this vehicle? Sometimes the compressor is designed to disengage in times of a high engine load (reverse?). This could possibly operating as designed. Does the compressor just disengage or are you getting warm air when driving? Most newer vehicles regulate the displacement of the compressor to get the desired cooling, some may disegage the actual clutch.
The reverse has me puzzled. With just normal driving I'd say this 11+ year old system is either low on charge or you may have moisture in the system and the evaporator core or TXV is freezing.
