2003 Pontiac Montana Problems

Intake Manifold Gasket May Leak Coolant or Engine Oil

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.

Erratic Shifting of the Automatic Transmission

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Bought with 14K miles and now with 145K. Except for routine maintenance I have only had to replace the intake manifold gasket and water pump. Now the head gasket is leaking and needs replaced. Engine still runs great with good performance. The plastic bottom panel hides the rust well. No electrical problems. It has been very reliable.
Purchased a 2003 Montana with about 20,000 miles on it. The thing with the Montana is that a lot of annoying little things go wrong. The fuel gauge does not work, warning lights go off when there are no actual problems, lower plastic side panel gets knocked off in a car wash, doors have to be unlocked/locked and unlocked again to open ... it does not inspire confidence. I am very fortunate t...
I bought mine used, and it came with electrical problems. Still hunting some of them down even now, a year later. There is plenty of power for this van, and it does so much better than the Dodge Caravan. I have the extended van, and have been able to haul three 3/16" sheets of drywall, a fullsize couch and other items in the back without too much problem. We've also had it full of kids. T...
