YM129915-77051 Komatsu HEATER

This part is basically a small radiator that sits inside your dashboard. Engine coolant, which is the warm fluid that keeps your engine from overheating, flows through it. A fan blows air across the fins of the heater core, and that’s what gives you warm air when you turn on the heat in your car. It's a heat exchanger – it exchanges heat from the engine coolant to the air in your cabin. It’s a key part of your vehicle's heating system. The heater core receives hot engine coolant, and the blower motor pushes air over it to provide heat for defrosting windows and keeping you comfortable. It works alongside the thermostat, radiator, water pump, and the blower motor to create a complete heating and cooling system. Well, imagine driving in the winter with no heat. Not fun, right? A failing heater core can lead to no heat at all, or only lukewarm air. You’ll notice if you start smelling a sweet, almost syrupy odor inside the car while driving – that's coolant leaking, and usually a sign the heater core is going bad. It acts like a shield protecting you and your passengers from the cold. Left untreated, a leak can also cause foggy windows, and coolant loss, which can lead to serious engine damage. You can find replacements pretty easily, Fixparts Online has a good selection, and it’s a part you definitely want to address quickly.
