1.05L REVOTORQ ENGINE 75 Testing Parameters :  Thermostat start open temperature is 86º to 90ºC at 0.1mm travel.  Full open travel of 8 mm (Min.) at tempera- ture is 100º C  Leakage through main valve at room tem- perature and 0.3 kg/cm 2 is 1500cc/min MAX. D. Water Pump : The water pump is a simple centrifugal pump driven by belt. The pump circulates the engine coolant when it is driven by the engine. The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the center continuously. The inlet to the pump is located near the center so that fluid return- ing from the radiator hits the pump vanes. The pump vanes fling the fluid to the outside of the pump, where it can enter the engine. The fluid leaving the pump flows first through the engine block and cylinder head, then into the radia- tor and finally back to the pump.
