Cooling, heating and ventilation systems
The cooling system on all models consists of a radiator, a coolant pump, a thermostat and an electrically-operated radiator fan. The system is pressurised and incorporates an overflow container. The system used on the OHV engine differs from that used on the CVH engine in layout and location of components. The coolant pump on the OHV engine is driven by the alternator drivebelt, while the pump on the CVH engines is driven by the toothed timing belt.
