The thermostat is a multi-stage device located in the coolant pump inlet to provide fast response and control of the engine outlet temperature. The thermostat independently controls the engine coolant flow in the cylinder block, improving engine warm up times.
The thermostat housing has 4 hose connections. The lower hose connection receives a quick fit connector which receives engine coolant from the radiator lower hose and the ATF cooler. The upper hose connection is connected to the engine coolant outlet pipe. The engine coolant flow from this connection is governed by the electric thermostat. The larger hose connection at the side provides engine coolant flow to the coolant pump. The smaller connection at the side receives engine coolant from the heater core and the coolant expansion tank.
