Theromstat Location?

Follow the top radiator hose from the radiator to the motor. That 's where the thermostat will be found.

You should know that your car's motor really can't be overheated or its cylinder head gasket will break. These engines are quite sensitive to being overheated so good cooling system maintenance is needed.

I thank you so much for your help. Can I go to a regular mechanic to install it or a mercedes mechanic? Thanks JLP

Any mechanic can replace a thermostat for you.
