How to Replace the Thermostat on a Volkswagen Vehicle

Model: Volkswagen Volkswagen Various
Part: Thermostat

Video tutorial

Replacing the thermostat on a Volkswagen vehicle may seem complex, but with the help of our video tutorial and written guide, you can perform this operation independently. When the engine has cooled down, unscrew the cap of the expansion tank.

Using appropriate tools, move the hose clamps around the pipes, place a container underneath, and wait for the coolant to completely drain out. Now proceed to remove the thermostat. Unscrew the top part of the air filter, remove the intake hose from the air inlet pipe, disconnect the airflow connector, loosen the clamp, and remove the top part of the filter.

Once the bottom part is removed, we can proceed to remove the battery. Remove the intercooler pipe by unclipping the clamps and completely remove the air pipe.

Continue by removing the water pump connector and then remove the pump itself. Also, remove the fuel filter.

Finally, you will have access to the thermostat; remove the old valve and begin installing the new valve. Reassemble all previously removed parts in reverse order.
