The thermostat is located in the thermostat housing which is bolted to the cylinder head and allows rapid engine warm-up by restricting When the engine is cold and the thermostat is closed, coolant flows from the water pump through the engine. It then returns to the water When the engine is warm and the thermostat is open, coolant flows into the radiator through the upper coolant hose. It then returns to the The heater core is on a parallel circuit and is unaffected by the position of the thermostat. Radiator The radiator is of aluminium construction with plastic end tanks. Foam seals are fitted to the radiator to prevent the cooling air from by Electric Cooling Fans Two variable speed electric cooling fans are housed in the cooling fan shroud for the cooling of the radiator. The speed of the electric The ECM determines the cooling fan speed by receiving inputs from the cylinder head temperature (CHT) sensor. The ECM sends a variable When the engine is running with the CHT above 100°C (212°F), if the ignition switch is turned to the OFF position the cooling fans will If the PW M signal from the ECM to the cooling fan control module is between 7% and 95% the cooling fan control module will operate the Coolant Recovery System A pressurized coolant expansion tank system is used which continuously separates the air from the cooling system and replenishes the A continuous vent from the engine and radiator to the coolant expansion tank prevents air locks from forming in the cooling system. The coolant expansion tank serves as the location for: service filling. Engine Oil Cooler The engine oil cooler is a oil to water type. The oil cooler is mounted to the oil filler housing an sealed with two O-ring seals. The coolant supply for the engine oil cooler is through the radiator bottom hose. Engine oil cooler thermostat The engine oil cooler thermostat is located in the water pump housing and helps to reduce the warm-up time by limiting the coolant flow |
