Gates 04-06 Mazda 3 4-Cyl. 2.3L Water Outlet To Pipe Molded Heater Hose

This is the molded heater hose for your 2004-2006 Mazda 3 with the 2.3L 4-cylinder engine, and it also fits the 2006-2009 Mazda 5. It's the specific hose that runs from the water outlet on your engine to the heater pipe, circulating coolant to keep your cabin warm on chilly days. When this hose starts to fail, you might notice coolant leaks around the engine or a drop in cabin heat.

Gates makes these hoses using a durable rubber compound that's built to handle the heat and pressure of your cooling system. It's molded to the exact shape needed, so it fits right without any fuss. This means you won't have to fight with it during installation, and it'll seal up properly to prevent leaks. It's a straightforward replacement part designed to get your heating system working like it should again.
