2001 Buick LeSabre Problems

Hydro-Lock Due to Internal Coolant Leak From Intake Manifold

The upper intake manifold may develop an internal coolant leak causing one or more cylinders to fill with coolant. This can cause the engine to "hydro-lock" and not turn over. Removing the spark plugs will allow the engine to turn over pushing the coolant out of the spark plug holes. Replacing the upper intake plenum and gasket is commonly required to correct this condition.

The engine can be very difficult to start after this problem has been repaired, it can be helpful to clear as much of the coolant from the intake manifold and cylinders as possible before reassembling the intake manifold.

Check Engine Light Due to Ignition Related Failures

Failure of the crankshaft position sensorignition control module, or powertrain control module (PCM) may cause the Check Engine Light to illuminate.

Intake Manifold Gaskets Can Develop Engine Oil Leaks

The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.

My 2001 lesbre has been one of the best car I've bought in a while the only problem I've had since day one was the fuel gauge bounce from empty to full which I took care of by replacing the fuel sender I bought from eBay for 27 dollars and it took me about 20 minutes to replace other than that I have no complaints
I bought my 2001 Buick Lesabre car at a small car dealership, one I've bought from before,here in my town. The check engine service soon came on and stayed on right after I bought it.
