Four Seasons Engine Coolant Outlet Flange

The Four Seasons Engine Coolant Outlet Flange (also called a thermostat housing, water outlet or coolant outlet housing) is a replacement part for the engine cooling system. It connects the thermostat area to the radiator hose. It gives coolant a sealed path out of the engine, so the cooling system can hold pressure and regulate temperature.

Key Features:

• Replaces a worn, cracked, corroded or leaking coolant outlet flange
• Designed to restore proper coolant flow and a secure hose connection
• Helps the thermostat work correctly so the engine reaches and holds its operating temperature
• Made by Four Seasons, a long-time name in engine cooling and climate control parts
• Suited to both routine maintenance and cooling system repairs

Replacing an aging coolant outlet flange can help prevent coolant leaks, overheating and the engine damage that can follow. Always replace the gasket or sealant and check the thermostat, hoses and coolant condition during installation.
