Removing and installing the radiator
Disconnect the ground wire from the battery clamp.
Remove the multi-pin connector from the fan motor housing.
Remove the fan shroud (Fig. 2.97).
Drain the cooling system through the lower radiator nipple.
Remove the cooling system hoses.
Unscrew the two mounting bolts and remove the radiator (Fig. 2.98 and 2.99).
Leaky cooling system components cannot be repaired and must be replaced with new ones. The radiator is installed in the reverse order of removal.
Fill the cooling system with liquid, gradually pouring it into the expansion tank. Bleed the cooling system as described earlier. From time to time, to clean the grille, blow out the radiator from the outside with compressed air. The blowing direction should be opposite to the air flow when the car is moving forward.
Coolant
The coolant that fills the engine cooling system takes away heat and transfers it to heat exchangers, which are the radiator and the heater in the car's interior.
The liquid is resistant to freezing at low ambient temperatures and has anti-corrosion additives that protect parts with which the coolant comes into contact from corrosion.
It is recommended to use liquids produced by Ford or Castrol. These liquids do not freeze to -30°C and can be used all year round.
The cooling systems of individual engines of the Ford Fiesta have the following volumes:
- engine 1.1 - 7.1 l
- 1.4i engine (with injection) - 7.6 l
- 1.6i engine (with injection) - 7.8 l
- diesel engine 1.8 - 9.3 l
