Dorman - OE Solutions HVAC Heater Hose Assembly P/N:626-626
Keep engine coolant flowing to the heater core with this Dorman heater hose assembly, part number 626-575, an OE FIX inlet hose built with an upgraded aluminum T-connector. It is a direct-fit replacement for the 2005-2008 Mazda 6. See the Buyer's Guide tab for engine details.
Factory heater hose assemblies often fail because cracks form in their plastic T-connector. Dorman's OE FIX version replaces that plastic piece with an aluminum T-connector, designed to help prevent the same failure from happening again.
Signs your 2005-2008 Mazda 6 heater hose may need replacing include coolant drips or puddles, a crack at the T-connector, a low coolant level, or weak cabin heat. Inspect the cooling system to confirm the source of the problem before replacing parts.
