Volkswagen 7H0819324 Hose

Description

This Volkswagen Hose, MPN 7H0819324, is a critical component of the vehicle's HVAC system, specifically functioning as a heater hose. It is used to circulate warm engine coolant to the heater core, providing heat to the cabin. This hose is manufactured to ensure reliable fluid transfer and withstand the high temperatures and pressures of the engine cooling system, offering long-lasting durability and consistent performance. The dimensions of this hose are 25 x 25 x 220 mm.

Key Features & Benefits

These hoses circulate hot engine coolant to your heater core. The heater core is basically a small radiator inside your dashboard. Coolant goes in, and the blower fan blows air across it, giving you warm air for defrosting or just staying comfortable inside the car. It’s a closed loop system – coolant goes from the engine, through the heater core, and then back to the engine to get reheated. Think of it as part of your car’s climate control system. It's not directly involved in making the engine run, but it's essential for comfort and visibility, especially in colder weather. It's a fairly simple part, honestly, but a vital one. Usually there's an upper and a lower hose, connecting the engine to the heater core.

Symptoms, Risks & Replacements

Well, if it fails, you'll quickly notice. You’ll suddenly lose heat inside the car, and you might even see coolant leaking. That leaking can cause overheating, and nobody wants that. These hoses are rubber, so they get brittle and crack over time from the heat and pressure of the coolant. It’s a relatively inexpensive part to replace, and doing it proactively can save you from a much bigger problem down the road. It’s one of those things that’s easy to put off, but really smart to check during regular maintenance.
