Frequently asked questions about car thermostat replacement & repairs

Read our answers to questions about car thermostat replacement costs, symptoms and more.

What does a Thermostat do?

The thermostat is part of the cooling system in every car. It consists of a metal valve that regulates the amount of coolant that flows to the engine. It maintains the engine's temperature at a constant and optimal level. If the engine runs hot the valve in the thermostat opens and lets more coolant flow to the engine (from the radiator) in other cases it stays closed.

What does a thermostat replacement involve?

  • Mechanic will read the ECU to see if there are any related fault codes.
  • Mechanic will inspect the thermostat and the cooling system.
  • If necessary, the mechanic will replace the thermostat.
  • Mechanic will close the cooling system and refill the system with engine coolant.
  • Mechanic will run the engine and, if necessary, test drive the car.
  • Mechanic will make any adjustments if necessary.

Do I need to replace the thermostat in my car?

Over time problems can occur with the thermostat due extensive use. The thermostat is in use when the engine runs with the valve opening and closing continuously, to keep the engine at the ideal temperature. It is one of the most common components in the cooling system to fail and can, moreover, lead to the engine overheating and potentially suffer severe engine damage.

Additionally, it can also get clogged up by dirt in the engine coolant meaning that less coolant can circulate through the system, causing the engine to overheat as well. Should you experience an issue like this or those listed earlier, it is advisable to have the thermostat inspected as soon as possible and, if necessary, have it replaced.

Can I drive with a faulty thermostat?

If you suspect there is any issue with your thermostat or there are concerns about its age or condition, book an inspection with a professional mechanic immediate effect and do not drive the vehicle.

Ignoring this warning light could lead to the engine overheating and cause serious damage to the engine. It is recommended to stop as soon as it is safe to do so when the warning light illuminates so as to prevent any further damage to the engine.
