Gates 04-06 Mazda 3 4-Cyl. 2.3L Thermostat to A.T.F. Cooler Molded Heater Hose

This molded heater hose is specifically made to connect your 2004-2006 Mazda 3's thermostat housing to the automatic transmission fluid (ATF) cooler. It's built with a reinforced construction to handle the heat and pressure found in the cooling system, ensuring a reliable connection that won't leak. Because it's a molded hose, it follows the exact bends and curves needed for a direct fit, making installation straightforward without needing to fight a stiff, universal hose.

Gates uses a EPDM rubber compound for the inner tube and cover, which is known for its resistance to coolant and heat. This means the hose is designed to last and won't degrade prematurely from exposure to engine bay temperatures or the fluids it carries. Having the correct, form-fitting hose is important for maintaining proper engine temperature and ensuring your transmission fluid stays at its optimal operating temperature, which is key for the longevity of both components.
