Factory MOPAR Thermostats

Efficient engine performance relies on the condition of your temperature control system. The thermostat is a heat sensitive device that controls the flow of coolant into the engine. It is located between the engine and the radiator. The thermostat blocks the coolant from entering the radiator when the engine temperature is cool enough. Vehicle overheating, fluctuating temperatures and engine inefficiency indicate thermostat failure. Always replace thermostats on the onset of these symptoms to maintain optimum engine performance.
