7E1819031B Audi HEATERCORE

This thing is basically a small radiator, but instead of cooling engine coolant, it heats the air that comes into your cabin. Hot coolant from your engine circulates through it, and a fan blows air across the fins, giving you warm air for heat. It's a heat exchanger, taking the warmth from the engine and putting it where you need it. It’s a key part of your vehicle’s HVAC system—that’s heating, ventilation, and air conditioning. The heater core specifically handles the “heating” part. Coolant flows from the engine, through the heater core, and then back to the engine. The air from your blower motor passes over the core, and that’s what warms up your car when it's cold outside. Well, if it fails, you’ll quickly realize how important it is. You’ll notice if you suddenly have no heat, or only cool air blowing, even when the engine is warmed up. Sometimes, a failing heater core can leak coolant into the passenger compartment, which you’ll smell – it has a sweet, almost sickly smell. That’s a serious issue, and you'll definitely know it. It’s not just comfort, though. No heat in winter can cause defogging problems, impacting visibility. It acts like a shield against condensation on your windshield. A replacement heater core isn’t super fun to install—it often means taking a good chunk of the dashboard apart—but it's something you want to get fixed sooner rather than later. We carry a good selection here, and you can also find them online at Fixparts Online if you’re looking for options. Built to last: Heater Core (MPN 7E1819031B) comes with a 12-month warranty for your assurance!
