Thermostat Replacement
The thermostat prevents coolant getting to the radiator until the engine warms up. Once the engine reaches its operating temperature, the thermostat heats up and the thermostat valve opens. The thermostat helps reduce engine wear and tear and excess emissions.
When is Thermostat Replacement Needed?
If the engine is running hotter than usual, or if the vehicle's temperature gauge is hanging out on the low side and the heater isn't doing its job, it's probably time for thermostat replacement, along with replacing the gasket and gasket sealant. If a visual inspection shows an open thermostat valve, then thermostat replacement is needed.
