Review on AUTOHAUX Coolant Thermostat Assembly LF7015170 by Kyle Mack

Good Replacement The engine thermostat regulates engine temperature by controlling coolant flow. Faulty or defective thermostat: High temperature readings and engine overheating, low temperature readings and engine overheating, erratic temperature changes, coolant leaks around the thermostat housing or under the vehicle. How to set the thermostat: You can find your car's thermostat by starting at the upper radiator hose and following it to where it enters the top of the engine.
