How to Replace the Thermostat in the Ford Fiesta

Model: Ford Fiesta Fiesta 5, MK 5, MK V - Years 2002-2008
Part: Thermostat

To replace the thermostat in the Ford Fiesta, open the bonnet and access the components in the engine compartment: here, on the left side of the engine block, you will find the alternator, which must be removed by unscrewing its fixing bolts. Once the alternator is disconnected and removed, you can access the coolant passage pipe located underneath it: this pipe must be removed by unscrewing its bolts to access the thermostat beneath it. Therefore, the old thermostat can be extracted from its housing and replaced with a new one.
