HOWO T5G engine Thermostat Cover VG1500040105, also called thermostat housing.
It is installed at the coolant outlet of the engine block and is equipped with a thermostat to control the coolant circulation path.The compatible parts use Weichai WD615 series engines (336 hp, 371 hp, 410 hp).
Function
1. Fixing and Sealing the Thermostat: Serving as the thermostat housing, it provides a precise mounting cavity and sealing surface. Sealing with O-rings, gaskets, or flanges ensures no coolant leakage. The thermostat body is embedded within this seal.The cover is bolted to the cylinder block to form a complete thermostat assembly.
2. Controlling the Coolant Circulation Path: At low temperatures, the coolant only circulates in a small loop (engine interior, water pump, heater core), quickly raising engine temperature, reducing wear, and lowering emissions. At normal operating temperature, the thermostat wax expands, opening the main valve, allowing the coolant to enter the large loop. After being cooled by the fan/air, it flows back, ensuring the engine always operates within its efficient temperature range.
3. The cover integrates multiple water outlet interfaces: the upper water outlet connects to the radiator inlet pipe; the bypass port connects to the engine internal return water; and there is also a heater water pipe interface to realize the diversion, collection and directional flow of coolant.
