5Q2816738J Audi Line

This line carries hot engine coolant—that’s the stuff that keeps your engine from overheating—to your heater core. The heater core is basically a small radiator inside your dashboard. As the coolant flows through it, the blower fan blows air across it, and that’s what gives you warm air coming out of your vents. It’s a closed system, so the coolant goes from the engine, through this hose, to the heater core, then back to the engine. It’s a pretty straightforward job, really. It's a crucial part of your vehicle’s heating system. Without a good flow of coolant through this line, you won’t get any heat. It sits right in the engine bay, so it’s exposed to heat, cold, and all the grime that gets kicked up from the road. A failing heater hose can cause a lot of trouble. You’ll notice if you start getting cool air when you expect heat, or if you see coolant leaking under your car, especially near the engine. That’s often a sign the hose has a crack or a bad connection. It's not something you want to ignore, because a complete hose failure can lead to coolant loss, which can quickly overheat your engine and cause some serious damage. They’re rubber, so they degrade over time, get brittle, and can crack. Replacing it is relatively inexpensive insurance against bigger problems. You can find this specific line on sites like Fixparts Online, and it's a job many home mechanics can handle, though if you're not comfortable working on cars, a professional is always the best bet. Year-round reliability: Line (MPN 5Q2816738J) includes a 12-month warranty!
