OE Aftermarket Engine Coolant Thermostat Housing Kit

The OE Aftermarket Engine Coolant Thermostat Housing Kit is a replacement thermostat and housing assembly for the engine cooling system. It is also sold as a coolant thermostat kit with housing, water inlet or thermostat assembly. The thermostat sits where the upper radiator hose meets the engine. It controls coolant flow to help the engine reach and hold its proper operating temperature.

Key Features:

• Thermostat and housing together: replaces both the temperature-sensing valve and the housing that holds it.
• Regulates engine temperature: controls coolant flow to support cooling efficiency and steady engine performance.
• Direct-replacement design: intended to take the place of the original assembly.
• Helps prevent cooling problems: a worn thermostat or leaking housing can cause overheating or poor warm-up. Replacing them together restores normal coolant circulation.

A new thermostat housing kit is a practical repair for a stuck thermostat, a cracked or leaking housing, or an engine that runs hot or cold. Each variant in this product line has its own part number.
