The coolant flange, or water outlet, is a critical connector that directs coolant from the engine block to the radiator or heater hoses. Often manufactured from plastic or cast aluminum, these components are subject to continuous heat cycling and engine vibration, making them highly susceptible to cracking, warping, and leaking over time. This category provides exact-fit OE-specification replacement coolant flanges, many of which include pre-installed gaskets or O-rings for a complete and secure seal. Select your vehicle to find the durable, precision-engineered flanges required to restore your cooling system's integrity and protect your engine from overheating.
Genuine flanges will not warp under thermal stress, ensuring a lasting and watertight seal against the engine block.
