2002 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.

2002 Buick LeSabre Reviews

Bought this Lesabre used at 90,000 miles, now has 270,000. Had two of the most commonly found problems: 1) windows stick, requiring replacement of motor; and 2) fuel pump went bad, probably because I drove it to almost empty every fill-up. No transmission or engine problems. On cruise control it does better than the EPA estimate: at 65 mph gets 33-34 mph. One of the best full-size sedans.
Took this car in few repairs. Mechanic fixed 3 window regulators and got tranny rebuilt at 60k miles it did stall on me several times all times have taken in to Napa and other mechanics one of the engine coils misfired I spent $338 on getting new parts like module, crankshaft sensor and piston work done at 140k miles. The anti theft system had me locked in my car for 2 hours while waiting on as...
The air flow mass is preventing me from passing the marta inspection to get my 2015 stickers on my license plates.
