problem #1

Jul 252002

Blazer 4WD

  • miles
In Jan 99, thermostat appeared to fail and when I opened the radiator cap, noticed what looked like mud/grit in cap. Took the truck to the Chevrolet dealer, they said they did not know what it was. Ended up replacing intake manifold gasket, pulling and repairing/cleaning radiator and replacing thermostat. In July 2002, truck overheated again. Took it to Firestone where they recommended $1200 in repairs to flush out "coagulated" coolant (dexcool). Ended up replacing radiator, radiator cap, and thermostat (again) and flushing entire coolant system. Firestone personnel said this was a recurring problem on the Blazer with the dexcool breaking down and turning into a brown, muddy, gummy substance. Accoding to Firestone, GM has several tech bulletins out on this, but they refuse to do anything about it. This dexcool broke down after only 30,000 miles. Why has nothing been done about this" GM is knowingly selling a deficient product and they refuse to stand behind it. Please, can someone out there help us!?!?!"!
