Heater Assembly
Mitsubishi FUSO®

The Heater Assembly, also known by its part number MC140154, is a crucial component in a truck's HVAC system. It is responsible for generating heat to warm up the cabin of the truck during cold weather conditions. The assembly typically includes a heating core, blower motor, and control valves. The heating core is the heart of the assembly, where hot coolant from the engine flows through small tubes to radiate heat into the cabin. The blower motor is responsible for drawing in cool air from outside and passing it through the heating core to warm it up before distributing it throughout the cabin via air ducts. Control valves regulate the flow of hot coolant to ensure that the desired temperature is maintained inside the cabin. Overall, the Heater Assembly plays a critical role in ensuring driver and passenger comfort during cold weather conditions.
