Can I continue to drive if my car thermostat isn't working?
If you drive with a faulty car thermostat, you risk engine overheating and serious, expensive damage to your vehicle. If your car thermostat is faulty, have your vehicle checked by a technician as soon as possible.
How often does a car thermostat need to be replaced?
A car thermostat only needs to be replaced if it’s faulty. It is best practice to replace the thermostat when you change the coolant, or if overheating has occurred.
If it’s more than five years old, it pays to have your vehicle cooling system checked regularly by a cooling technician.
Can I change my car thermostat myself?
You can change a car thermostat if you follow the vehicle manual and instructions carefully. It’s also a good opportunity to replace the coolant and flush the cooling system to protect the new thermostat from contamination.
However, a faulty thermostat is not the only cause of abnormal engine temperatures. There could be a problem elsewhere in the cooling system. Consider a low coolant level, leaks, a faulty water pump, worn water pump belt, faulty radiator fan, collapsed or leaking hose, or a clogged radiator.
To prevent potential expensive damage, it pays to have a full cooling system check done by a qualified technician when you observe unusual engine temperatures.
Why is it important to choose a high-quality thermostat?
A thermostat accelerates engine warm-up and regulates the engine operating temperature. Choosing a high-quality thermostat will ensure your vehicle achieves excellent fuel economy, less wear on the engine, lower emissions, better driving in cold weather, effective cabin heating and avoidance of engine over-heating.
