1995 BUICK RIVIERA User Comment / Complaint

Dt*: the contact stated the vehicle was overheating and the warning light indicating the coolant needed to be replaced was illuminated. the coolant was replaced, but the problem continued. an independent repair shop determined there was a leak into upper plenum and upper manifold. the gaskets were replaced and the manifold was cleaned. the problem returned a year later, the mechanic determined the same problem occurred. the same repairs were made as well as valves and adapters were replaced. the problem returned and the vehicle was taken to the same repair shop.
