4.10325 DT Coolant line

Coolant hoses are pretty straightforward – they're the pathways for the coolant, that green or orange fluid, to circulate between the engine and the radiator. They carry the hot coolant from the engine to the radiator where it’s cooled down, and then carry the cooled coolant back to the engine to absorb more heat. It's a continuous loop, keeping everything at a safe operating temperature. They’re flexible rubber, designed to handle both high temperatures and pressure. Think of it like the circulatory system for your engine. The coolant picks up heat from the engine block—where things get very hot during combustion—and the hoses are the veins and arteries that move it all around. There's usually an upper and a lower hose, and sometimes others for heater core connections or turbocharger cooling. They connect to the engine, the radiator, and sometimes other components. They’re secured with clamps to make sure there aren’t any leaks. Well, if those hoses fail, you’ll have coolant leaking out. That quickly leads to overheating, and overheating can cause serious engine damage. Things like a warped cylinder head, blown head gasket, even a cracked engine block aren't uncommon when an engine gets too hot. A failing hose doesn’t always leak immediately though. Sometimes it will bulge or soften over time. You’ll notice if one starts to swell, crack, or feel mushy when you squeeze it. Regular inspection is a good idea. Replacing them before they go bad is way cheaper than fixing an overheated engine. We carry a good range of them at Fixparts Online, and honestly, it’s one of those things that’s best to keep on hand if you do your own work, just because of how quickly a failing hose can cause trouble. All-season performance: Coolant Hose (MPN 4.10325) comes with a 12-month warranty!
