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 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
My car has 260,000 miles,bought it with 140,000 as it aged seemed to have alot of sensor problems and throwing codes, but all in all I would buy another, Love Pontiacs for durance.
I bought my GP-GT new in 2000. I now have 107,000+ miles on it. My only complaint has been with the A/C (had to disconnect and use an ideler pully to replace compressor) and the de-fogging function which has always been overpowered in winter w/ very humid/snowey weather. The HVAC Blower has bad some very noisy screeching noises as well. Have gotten 31 MPG highway and about 17-18 MPG in all-around daily use. It is starting to show rust under the car and door sill areas, but the body/silver paint has been fantastic even after spending 12+ years out of 13 parked outside here in our Michigan winters/summers.
very good car, obtained car in 2011 from friend who mother owned the car. I replaced the waterpump, alternator, back struts, battery, door locks module, that was a problem, did not know what was the problem, the locks would humm from one door to the other all around the car all four doors. went to the dealer and they said that they could not help. I went to a electrical shop and they found the problem was a module for the chimes and door locks, got a used one solved the problem. Now I have a problem with anti-freeze leaking from under the car, think its the timing cover.
After a horrible experience with a 1993 VW Jetta I purchased new, I decided to trade my 1993 Jetta with 26,500 miles on the odometer for a brand new 1997 Pontiac Grand Prix GT coupe. I still have my beautiful Grand Prix and I have no intentions of ever parting with it. I'd like to be buried in it when I die! I can't believe the incredible durability of the Grand Prix's paint and interior. My Grand Prix is mostly parked outdoors and after nearly 15 years the paint still looks great and the incredibly durable cloth interior is virtually fade proof and is tough as nails! The 3800 V6 is smooth, powerful and gets fantastic gas mileage coupled to an excellent 4 speed automatic transmission. The interior is very roomy as is the trunk. My Grand Prix has been a very solid and extremely reliable car, with excellent handling, firm magnasteer steering and strong ABS brakes. Not to mention it's a very inexpensive car to own and operate. My only gripe is with the slow power window motors and the poor optics of the headlamps. But aside from those issues, GM did a phenomenal job with the redesign of the 1997 Grand Prix. I deem it as a perfect all around car!
