It’s a small part with a great importance. The thermostat manages the coolant flow through the radiator. When the engine is started and cold, the thermostat is fully closed. Engine coolant does not go through the radiator at all. Along with temperature rise of the engine, the thermostat starts to open. When the optimal temperature is reached, the thermostat is fully open. This results in a maximum radiator flow. When the system temperature drops again, the thermostat closes and so on.

Customer reviews and star ratings help our customers learn more about a product and decide whether it is worth buying. A complex algorithm is used to calculate the star rating, taking into consideration how long ago the review was made, whether the item was actually purchased in the AUTODOC online shop, and whether it was returned or not.
The tag "verified purchase" allows you to find reviews from customers who have actually purchased the item in question from the AUTODOC online shop. The "verified purchase" label applies to reviews of items purchased from the same account the reviews were submitted from.
