Thermostat replacement

How much does a thermostat replacement toll?

You might recall your engine thermostat's only purpose is to forbid overheating, only that's not all it does.

Your engine thermostat also restricts coolant flow on warmup to create oestrus inside your automobile sooner, and to get the engine into the best operating range for proper emissions.

Over time and by constantly opening and closing during operation, the thermostat can get weak, get stuck open or closed, or go restricted by corrosion buildup.

Yous can expect thermostat replacement to be between $150 and $250 for most vehicles, although some are exponentially more due to vehicle design.

What is a thermostat?

A thermostat is a small, mechanical valve within the cooling system. When the thermostat is below operating temperature, a spring keeps information technology closed.

It prevents engine coolant from flowing through the coolant hoses to the radiator, keeping coolant inside the engine until it warms up.

As the engine temperature increases to the thermostat'south operating temperature, a small charge of wax inside the valve expands and opens the valve, and the water pump can circulate the engine'due south coolant throughout the cooling organization

As the heat dissipates, the wax contracts and the valve closes. This cycle repeats over and over once more until the engine is shut downwardly and cools off.

Symptoms that a thermostat replacement is required

• Your engine doesn't go upward to operating temperature.
• No estrus coming through your nuance vents.
• The temperature gauge spikes to full hot while running, and your engine overheats.
• The Check Engine low-cal illuminates for coolant temperature codes.

How is a thermostat replacement performed?

• The cooling system is drained and the technician locates the thermostat, typically on the engine past the upper radiator hose.
• The thermostat housing is unbolted from the engine.
• The failed thermostat is removed and a new one is installed in its identify, noting the exact orientation of the old role.
• The cooling arrangement is refilled with coolant and the engine is run to operating temperature to confirm the repair.

Tips to remember

• When removed from your machine, the thermostat tin exist tested past putting it in hot water and monitoring the temperature at which it opens with a thermometer.
• A thermostat installed backwards may still function, albeit less effectively.
• A new gasket should always be used when re-installing the thermostat housing.

How important is a thermostat replacement?

If the thermostat has stuck closed, it could spell an overheating condition that will damage your engine and cooling system.

Along with that comes expensive engine repairs. A thermostat stuck open tin cause your engine not to achieve operating temperature, meaning more fuel consumption, poor emissions, and lack of heat inside your car.
