Gates 10-12 Mazda 3 4-Cyl. 2.0L Upper Molded Coolant Hose

This is the Gates upper molded coolant hose for your 2010-2013 Mazda 3 with the 2.0L 4-cylinder engine. It connects your engine's thermostat housing to the radiator, carrying coolant to keep your engine from overheating. Hoses can become brittle and crack over time, especially with heat cycles, so replacing a worn hose is important for reliable cooling.

Gates uses a heat-resistant EPDM rubber compound for the inner tube and cover, which is reinforced with polyester yarn. This construction helps the hose withstand the high temperatures and pressure found in your cooling system. Because it's a molded hose, it's shaped specifically to fit your Mazda 3's engine bay without needing to be bent or kinked, ensuring proper coolant flow and making installation straightforward.
