The cooling system is of pressurised type incorporating an expansion bottle or expansion tank according to model. The system includes a front-mounted cross-flow radiator, thermoswitch controlled electric cooling fan, coolant pump and thermostat. The car interior heater matrix is incorporated into the coolant circuit with the interior air supply and distribution being controlled by air flaps. On XU and TU Series engines the coolant pump is driven by the engine timing belt, but on all other engines it is driven by the auxiliary (alternator) drivebelt.
