| I bought my 1996 impala ss brand new, and every year since then in the winter time i loose the heat. the dealer, while the car was still under warranty, would flush the heater core and sometimes replace it yearly. the problem still is not fixed, and i have lost the heat in the car again and the dealer will no longer fix the problem because they claim it is out of warranty even though they have all of the service records showing the history of the problem. i think this is totally unfair to the owner, and i have talked to many caprice/impala ss owners of this year who are going through the same problem. chevy knows of the problem but does nothing to correct it, and now the owners are left with the bill and if you cannot afford to have them fix it you drive in a cold car. if they do not know what is causing this problem, then chevy/dealership should be responsible for flushing or replacing my heater core(whatever is needed to restore the heat) for as long as i own the car. i need some help with this, i am only a small guy fighting a giant. any assistance you can provide would be greatly appreciated. thanks kjb. ts | |||

| Coolent dex cool failed at half its warranty and car damagingly overheated. this failure caused the replacement of the coolant reservoir, radiator, thermostat, water pump. it also required days of flushing out the heater core and the cooling system. it may have permanently damaged an expensive high performance engine. | |||

| Cracked cylinder head gasket is causing engine to overheat and coolant leakage, consequently creating a potential engine fire. prior engine coolant leakage caused damage to the water pump, power steering assembly, and possibly the current head gasket defect. prior coolant leakage onto the power steering belt caused power steering failure that required replacement of the power steering belt and engine serpentine belt. power steering belt and engine serpentine belt were replaced sept. 1999. water pump was replaced nov. 2000. | |||

| Abs light comes on at random indicating that abs is disabled, restarting the vehicle resets this condition for a while, dealers unable to diagnose or repair. egr and egr solenoid failed, 3 visits to dealer did not fix problem, but rather on two occassions they deliberatly disabled the egr system to hide the problem from me. i finally repaired the problem myself by replaing the egr solenoid at my own expense. | |||
