1990 Buick Riviera ProblemsABS accumulater may fail
The anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)
The air conditioning system can be prone to refrigerant leaks and failure of one or more pressure sensors. The AC pressure sensors should be checked for proper operation when ever the AC system is serviced.
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
