Thermostats

Between the radiator and the engine in your car, you will find a thermostat. It handles regulating the amount of coolant is delivered to the engine. If the car is cold, there is no coolant sent to it. Once the vehicle warms up, the thermostat allows coolant to begin to flow into the engine. This keeps the engine at an even temperature. If the engine starts to overheat, it may be because there is a problem with the thermostat. They can stick open or closed, which impedes the proper amount of coolant to be sent to the engine. An engine that has overheated can become damaged to the point of no repair.

If you need to replace the thermostat in your VW Quantum, you want to use a genuine OEM replacement part. This way, you know that the part that you are using is made to fit exactly how the factory designed it to fit. A loose fitting part does not offer the same performance as a factory part. We do not carry fake or imitation parts – all parts are factory. The thermostat is instrumental in ensuring that the engine warms up quickly. This keeps the wear and tear down on it and reduces deposits and emissions.

We offer excellent customer service, with free parts look-ups by phone. We have a no-hassle return policy. Call us today and order your Volkswagen parts.
