NHTSA Complaint #10047001 — 1997 CHEVROLET BLAZER

97 BLAZER COOLING SYSTEM FAILURE. FROM THE TIME I BOUGHT THE CAR THE COOLING SYSTEM HAD TROUBLE. THE RADIATOR HAD A LEAK ( 34391 MILES), THE COOLING SYSTEM CLOGGED UP AND THE HEATER CORE LEAKED FROM DEX-COOL GELLING UP ( 65265 MILES ), AGAIN HEATER CORE LEAKING FROM BAD DEX-COOL ( 104044 MILES ), HEATER CORE LEAKING (114387 MILES). EACH TIME THE HEATER CORE HAD TO BE REPLACED. THE COOLING SYSTEM HAD TO BE ACID FLUSHED BY THE DEALER BECAUSE THE DEX-COOL GELLED UP. ALL THESE REPAIRS WHERE DONE BY GM DEALER. THE DEALER COULD NOT TELL ME WHY THE DEX-COOL WAS GELLING UP OR THE HEATER CORE KEPT LEAKING. I FILED A COMPLAINT WITH GMC (COMPLAINT # 1-152407734) GMC COULD NOT HELP ME. I FOUND OUT FROM A RADIATOR REPAIR SHOP THAT THEY HAVE HAD MANY GM COOLING SYSTEM FAILURES DU TO THE DEX-COOL CAUSING ELECTROLYSIS. THIS IS THE MAIN CAUSE OF MY PROBLEM AND GM AND THE DEALER WILL NOT ADDRESS IT. THE RADIATOR SHOP SAID THE ONLY REPAIR IS TO FLUSH OUT THE COOLING SYSTEM FOR 36 HOURS THE REFILL IT WITH ANTIFREEZE, NOT DEX-COOL. ALSO ADD AN ANTI-ELECTROLYSIS SOLUTION TO IT AND A RADIATOR CAP WITH AN ANODE ROD ON IT. THEY HAVE HAD VERY GOOD RESULTS WITH THIS REPAIR. THERE MANY COMPLAINTS ON YOUR SITE ABOUT THIS AND ALSO MANY ON OTHER AUTO REPAIR WEB SITES. ALL I WANT IS TO BE REFUNDED THE MONEY I SPENT ON REPAIRS FROM DAY ONE AND HAVE GM PAY FOR THE RADIATOR SHOP TO DO THE FLUSHING AND REPAIRS. *LA
