Water pump and thermostat

Description 1088C

1.1, 1.2 8v

It is the centrifugal type with vanes, fixed to the crankcase and directly directly by the timing belt.

1.3 JTD 16v

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 service belt.

1.1, 1.2 8v

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

• at a temperature of < 87 ± 2° C the (closed) thermostatic valve directs the coolant directly towards the pump
• at a temperature of > 87 ± 2° C the (open) thermostatic valve directs the coolant towards the radiator.

The coolant temperature sensor connected to the fuel injection control unit is fitted to the thermostat (see see 1056).

1.3 JTD 16v

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.
