Four Seasons Engine Coolant Hose Flange

The Four Seasons engine coolant hose flange, also called a coolant outlet flange, thermostat housing flange or water outlet flange, is a replacement part for the engine cooling system. It connects the radiator or heater hose to the engine. It also helps route coolant to and from the engine so the cooling system works as designed.

Key Features:

• Replacement coolant hose flange that gives the hose a secure connection point on the engine
• Helps keep the coolant seal tight to reduce the risk of leaks, overheating and engine damage
• Built for durability under repeated heat cycles, pressure and exposure to coolant
• Made by Four Seasons, a long-established name in engine cooling and climate control parts
• Designed as a direct-fit replacement for the original part

Cracked, corroded or leaking coolant flanges are a common cause of coolant loss and engine overheating. Replacing a worn flange restores a reliable seal and helps protect the engine. When you replace the flange, also inspect the gasket or O-ring, the hoses and the coolant condition.
