MAN 33779640194 Heater Hose

Description

The MAN 33779640194 is a heater hose used within the HVAC system to circulate warm coolant to the vehicle's heater core, providing heat to the cabin. This hose is designed for reliable fluid transfer in demanding engine environments. Measuring 25 x 97 x 162 mm, it provides a precise fit and consistent performance. Its durable construction ensures resistance to cracking, bursting, and degradation from coolant exposure, resulting in a long service life and minimizing the risk of leaks.

Key Features & Benefits

This hose basically carries hot engine coolant – that’s the fluid that keeps your engine from overheating – to your heater core. The heater core is like a little radiator inside your dashboard. The coolant warms it up, and then the blower fan pushes air across it, giving you heat inside the cabin. It’s a pretty simple system, but relies on these hoses doing their job. There's usually more than one, often an upper and a lower to create a loop. It’s part of your vehicle’s heating and cooling system, specifically the part that provides warmth to the interior. Think of it as a vital link connecting the engine’s warmth to where you are sitting. It's not directly involved in keeping the engine cool, but it utilizes the engine's heat.

Symptoms, Risks & Replacements

Well, if this hose fails, you’ll likely lose heat inside the car. You’ll notice if it’s a really bad leak – coolant will probably be dripping inside the vehicle, or you’ll see it under the hood. More subtly, a pinhole leak can cause a gradual loss of coolant, which can lead to overheating if you’re not careful. It acts like a shield, keeping the hot coolant where it needs to be and preventing it from spilling. They get old, they get brittle, and they crack, especially with temperature changes. Fixparts Online has a good selection of these, and replacing them is a relatively inexpensive way to avoid a bigger problem down the road.
