Thermostat

Refine Results

A thermostat regulates engine temperature by controlling the coolant flow while the car runs. This device can be found between the engine and the radiator of the car, and opens or closes according to the current engine temperature. MoparGenuineParts offers genuine OEM thermostats and components for several Mopar brands like Dodge, Jeep, and Ram vehicles.

Control Engine Temperatures Using Car Thermostats

Modern cars are built to operate at a maximum range of temperature efficiency to optimize its performance. Car thermostats help in maintaining this efficiency by controlling the engine temperature of a car as it runs. Car thermostats are situated between the engine and the radiator. 

This device opens and closes to control the flow of coolant of a liquid-cooled engine. The thermostat remains closed and prevents the engine coolant from flowing into the radiator, making the coolant increase in temperature. Once the coolant reaches a temperature of 180 F (82 C), the thermostat opens. At this point, the thermostat allows the now-hot coolant to pass through, letting it flow to the radiator where it will be cooled, then pushed back to the engine to help regulate the rising heat. It’s a simple but significant process that keeps the engine from overheating and performing to its highest efficiency.

While car thermostats are designed to last for years, they are not immune to wear and tear. If your car keeps on overheating, underheating, or has an erratic engine temperature, chances are that your thermostat is already faltering. Replace your car thermostat regularly to keep your engine running efficiently.
