70818871 MAHLE Interior heat exchanger

This part is basically a small radiator, but instead of cooling engine coolant, it heats the air that comes into your cabin. Hot coolant from the engine flows through it, and the blower fan blows air across the fins of the core, warming the air before it comes out of your vents. It’s how you get heat in the winter. It’s a key part of your vehicle’s HVAC system – that's heating, ventilation, and air conditioning. It sits inside the dashboard, usually tucked away behind the glove box. Coolant comes in one side, gets warmed up by the engine’s heat, and then flows out the other side after giving up its warmth. The core acts like a shield between your engine’s hot coolant and the air you breathe, transferring the heat safely. Well, without it, you’d have no heat. You’ll notice if it fails pretty quickly, especially in colder months. You might get lukewarm air, or no heat at all. A failing core can also cause a sweet, almost sickly smell inside the car – that’s coolant leaking into the cabin air. It’s also possible to see dampness on the passenger side floor. It’s not something you want to ignore, because prolonged leaks can cause corrosion and even make the interior damp and moldy. You can find a replacement pretty easily, and Fixparts Online carries a good selection of them if you’re looking for a source.
