Private Party Value is the amount a buyer can expect to pay when buying a used 1994 Oldsmobile Ciera from a private party. The Kelley Blue Book Suggested Retail Value is representative of dealers' asking prices for the 1994 Oldsmobile Ciera, and the starting point for negotiation between a consumer and a dealer.
The thermostat in the 1994 Oldsmobile Ciera regulates the temperature of the engine. When the coolant fluid reaches 190 degrees, the thermostat opens and lets more fluid through the engine passages. In turn, this pushes more fluid through the radiator, which cools it. This brings the temperature of the engine down. If the thermostat stops opening, the result is an engine at risk of overheating. The only way to resolve the issue is to replace the thermostat with a new one.
