2003 Chevrolet Monte Carlo Problems

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

The water pump may develop a coolant leak resulting in an engine overheating condition.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

The key fob (if applicable), should also be removed from the key ring. Dealers will provide two replacement key rings and key cover on all ignition keys to correct this concern.

Love my 2003 SS! 611,200km and still running! Just changed my first water pump and alternator in it this winter!

I have been pretty rough on this car but it has served me well. The only issues I've had are with the oxygen sensors and the catalytic converter. Both have had to be replaced multiple times. Other than that I have 132k miles on this baby and she still has some get up and go.
