The Cooling System is a pressurized type, where the
water pump, which is cambelt driven, forces the
circulation of the coolant through the cylinder block and
head. The thermostat regulates the flow of coolant
between the radiator and the bypass circuit. The heater
is part of the bypass circuit. The throttle body pre–heat
is a separate circuit which is not regulated by the
thermostat. An oil cooler may be fitted as part of this
circuit.
