Cooling system operation (Cooling system - L Series) (page 2 of 2)

The radiator (7) is a copper/brass cross-flow type with moulded plastic end tanks which incorporate sensor mountings and is mounted on rubber bushes directly into the front body member. The top of the radiator is supported by means of mounting brackets bolted to the radiator and bonnet locking platform.

For additional air flow, at times when the vehicle is stationary, an electric cooling fan is fitted. This is triggered by the low temperature switch (on vehicles fitted with an intercooler) mounted in the top right hand side of the radiator or by the Engine Control Module (ECM) on non-intercooler vehicles.

The coolant pump (8) is a rotor type pump which draws coolant directly from the thermostat. The pump is driven by a geared pulley from the camshaft timing belt.
