Five problems related to engine belts and pulleys have been reported for the 1997 Buick Park Avenue. The most recently reported issues are listed below.
My factory installed supercharger has had a pulley mechanism fall apart. As a result the belt from this system (similar to a drive train belt) fell down through the engine compartment under the front passenger side tire abruptly stopping my vehicle as the belt was still attached to the another component in the engine. This has happened three different times and each time has involved a different pulley on the system.
The dealer replaced the plastic intake manifold, water pump, gaskets and serpentine belt. The vehicle only had 47000 miles on it. The vehicle had required many repairs while under warranty. The coolant tank kept going low and the upper and lower gasket along with all components. The water pump was replaced.
Serpentine belt separated from vehicle twice. Dealer and manufacturer were notified.
Serpentine belt came off on a crowded interstate at 70 mph, cutting an a/c hose so that engine fluid leaked out, resultging in engine overheating.
1997 Buick Park Avenue with a defective engine. Dealer informed the consumer of a manufacturer defect which is anti freeze leaking onto the oil chamber causing the engine to overheat and cause a fire. The consumer also stated the water pump leaked, which had to be replaced because it leaked onto the fan belt which caused it to break. (consumer wrote in on behalf of his aunt; owner of the vehicle).
