Transmission Fluid Leak From Cooler Line

The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.

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.

I purchased this vehicle in April 2003 with 11,000 miles. It has held up well, however, it apprears that this year model was plagued with power window problems. Same with my '03 Century. The electrical seems to have evolved, now the left rear door is always locked, no power to the locking motor and the odometer area bulb operates occasionally, the last time it lit up the odometer read 168,00...
We have had fairly good luck with our '03 Century. Had lifters replaced at 50,000 miles because of clatter at a Chevy dealer in Sandy. After 1000 mi or so it was as noisy as before. Were they actually replaced? Get better A/C on passenger side. Power window problems, but all in all its been a good dependable car. Its nearing 100,000 miles. p.s. replaced catalytic converter recently.
What can I say! I have driven a Volvo, several Fords and a Toyota and none of these vehicle compare favorably with my Buick. At over 300K miles (this is not a mistake) and counting, I have only had work done on the radiator recently. Outside of the normal wear such as brakes and some window issues, I have had no problems with this car. I intend to get another Buick Century.
