33.77965-5366 MAN HEATER LINE

The MAN 33779655366 heater line is a vital component of a vehicle's heating system, responsible for circulating hot engine coolant to the heater core. This allows for effective cabin heating, ensuring driver and passenger comfort. Manufactured in Germany, this heater line measures 40 x 110 x 233 mm and is designed for reliable performance and longevity, contributing to consistent heat distribution and a comfortable in-cabin environment. This part’s job is pretty straightforward – it carries hot engine coolant to your heater core. The heater core is basically a small radiator inside your dashboard. The coolant warms it up, and then the blower motor blows air across it to give you heat inside the car. It's a simple system, really, but relies on these lines being solid. It’s part of your vehicle’s heating system, obviously. Coolant circulates from the engine, through the heater line, into the heater core, and then back to the engine. It’s a closed loop. These lines connect everything together. You’ll typically have a supply line bringing the hot coolant to the heater core and a return line bringing the cooled coolant back to the engine. Well, if one of these lines fails, you’ll quickly realize it. You’ll notice if you suddenly lose heat in your car, especially on a cold day. A leaking heater line can also spray hot coolant, which is a serious issue and could cause burns. Sometimes a small leak might just create a sweet smell inside the car. They’re rubber or plastic, so they degrade over time from the heat and coolant, and can crack or burst. Honestly, it’s a relatively inexpensive part to replace, and doing it proactively can save you a lot of trouble. You can find heater lines pretty easily at places like Fixparts Online, and replacing them isn’t usually too difficult if you’re comfortable with basic car repairs. Convenience at its best: Heater Line (MPN 33779655366) includes a 12-month warranty!
