Four Seasons Engine Coolant Water Outlet

The Four Seasons Engine Coolant Water Outlet (also called a thermostat housing or water neck) is a replacement part for the engine cooling system. It forms the connection point where coolant leaves the engine and flows toward the radiator. On many engines it also holds the thermostat in place and seals it against the engine.

Key Features:

• Replaces the original water outlet or thermostat housing in the engine cooling circuit
• Gives a leak-resistant coolant connection at the engine
• Made to withstand constant heat cycling and exposure to coolant
• Helps the thermostat and cooling system keep a steady engine operating temperature
• Backed by Four Seasons, a well-known name in engine cooling and climate control parts

A cracked, corroded or leaking water outlet can cause coolant loss and overheating. Replacing it restores a sealed cooling system and helps protect the engine from heat damage. Choose the individual part number that matches your application from the options on this page.
