I have installed a new compressor so I no that is not locking up. Also how does the unit sense the tempature Thank You Tom Greenleaf Ultimate Carjunky / Moderator Jun 28, 2008, 1:59 AM Post #2 of 3 (2036 views) Re: AC BELT BREAKING Sign In I think this vehicle uses a "TXV" = Thermal Expansion Valve to regulate flow of liquid refrigerant to evaperator core. If overcharged for some reason compressor will work way too hard and thus will be hard on the belt. It's more likely that there's a belt tension problem or that the pulley on the compressor doesn't have the right # of grooves to match the others - if so a new belt won't last for squat - got the T-shirt as you don't always notice that right away. Check the # of grooves and valleys in clutch pulley and the rest of the pulleys, T brbettge User Jun 29, 2008, 8:46 AM Post #3 of 3 (2029 views) Re: AC BELT BREAKING Sign In as far as how this unit senses temperature....it doesn't. It works by "sensing" pressure. might also check the pully(s) for sharp edges...and "eyeball" the alignment of the pullys to be sure they line up.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
