Water pump and thermostat

Description 1088C

1.6 TS

Water pump

It is the centrifugal vane type, with an aluminium alloy pump casing and phenolic resin impeller.

Secured to the engine block and driven directly by the timing belt.

Thermostat

Mounted on the rear of the cylinder head, its function is to keep the engine at the optimum temperature:

• – at a temperature of < 83 ± 2 ° C the (closed) thermostatic valve directs the coolant directly to the pump
• – at a temperature of > 83 ± 2 ° C the (open) thermostatic valve directs the coolant to the radiator.

Mounted on the thermostat, there is the coolant temperature sensor connected to the fuel injection control unit Characteristic of working principle 1056 PETROL INJECTION SYSTEM.

COMPONENT DESCRIPTIONS

COOLANT PUMP

It is the centrifugal vane type, with an aluminium alloy pump casing and phenolic resin impeller.

Secured to the engine block and driven directly by the timing belt.

THERMOSTAT

Mounted on the rear of the cylinder head, its function is to keep the engine at the optimum temperature:

• at a temperature of < 80 ± 2° C the (closed) thermostatic valve directs the coolant directly to the pump
• at a temperature of > 80 ± 2° C the (open) thermostatic valve directs the coolant to the radiator.

The engine coolant temperature sensor, connected to the injection control unit and the instrument panel, is fitted on the thermostat Characteristic of working principle 1060G pressure pump electric control.
