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.

Pontiac Grand Prix Reviews
I really need to know if I should try changing my resistor blower motor since my heat/AC stopped working when I turn it on high?
Bought brand new, currently 114k miles, no major engine or transmission problems yet!! I love my car. Always used quality gas & got oil changed regularly. 1st tune-up at 100k miles, my ignition still starts like a brand new car. 1st major repair in 2013 hvac. Needs new struts but still handles & accelerates like new. I'm blessed.
brake lights and turn signals on rear went out replaced fuse and still does not work
I've only had my 93 Grand Prix LE for about 2 months. Other than a service engine light coming on it hasn't given me any problems. No oil leaks, no oil usage, air cond. works and breaks are fabulous. Very good engine power for a 20 year old car. The odometer says 53000?
I do not recomend this vehicle I love my 02 grand prix, I guess exterior mostly. I bought it used and had many problems. no kick in gas bumby ride always
