The 037121121A Coolant Flange is an OEM‑quality replacement designed to connect the engine block to the cooling system hoses while providing a sealed pathway for coolant flow. Located near the cylinder head, this flange keeps coolant circulating correctly and prevents overheating.
Over time, factory coolant flanges can crack, warp, or leak due to heat exposure and pressure. A failing flange may cause coolant loss, warning lights, or overheating. Replacing it with this durable OEM‑spec flange restores system reliability and peace of mind.
