1996 Chevrolet Impala

CLOGGED HEATER CORE DUE TO DEX-COOL COOLANT IN CAR. TOOK TWO TRIPS TO DEALER TO GET FIXED, AND THEN ONLY AFTER GIVING THEM THE TSB. DEX-COOL COOLANT IS KNOWN FOR CAUSING HEATER CORE BLOCKAGE, BUT GM REFUSES TO ADMIT IT, OR OFFER AN ALTERNATIVE. AS THE WARRANTY ON MANY OF THESE VEHICLES IS WEARING OUT, COST OF THIS CONSTANT FLUSHING OF THE CORE IS PUT ON THE OWNER. GM ADVERTISES THE DEXCOOL COOLANT DOES NOT NEED TO BE REPLACED, OR SERVICED FOR 100,000 MILES. THIS PROMISE IS OBVIOUSLY NOT BEING LIVED UP TO, AND THE OWNERS OF THE CARS ARE THE ONES PAYING THE PRICE. *AK

HEATER DOES NOT COME ON DUE TO HEATER CORE BEING CLOGGED. DEALER HAS FLUSHED THE SYSTEM, AND HEATER STILL DID NOT FUNCTION. WATER PUMP REPLACED. APPEARS THAT A CHEMICAL REACTION WITH DEX-COOL ANTIFREEZE, OEM STOPLEAK FACTORY TABLETS, AND ALUMINUM AND STEEL COMPONENTS INCLUDING FLOW RESTRICTOR CAUSE CONGEALING OF COOLANT WHICH CAUSES ACCELERATED LOSS OF HEAT UNTIL COMPLETE BLOCKAGE OF THE HEATER CORE OCCURS. DEX-COOL WAS NOT USED IN PREVIOUS GM MODELS, AND NO HEAT PROBLEMS EXISTED. CONSUMER BELIEVES A RECALL IS IN ORDER. *AK *ML
