Aisin Engine Coolant Thermostat Assembly with Gasket

The Aisin engine coolant thermostat assembly with gasket (also called a thermostat kit or thermostat with housing seal) helps regulate engine operating temperature. It opens and closes at a calibrated temperature to control coolant flow between the engine and the radiator. This helps the engine warm up efficiently and then stay in its proper temperature range.

Key Features:

• Supplied with a gasket to help seal the thermostat housing connection
• Designed to meet OE-style function and operating requirements
• Helps maintain consistent coolant temperature for steady engine performance and efficiency
• Supports reliable cold-start warm-up and cooling system operation
• Made by Aisin, a well-known OE supplier of engine cooling and drivetrain components

Replacing a worn or sticking thermostat helps prevent overheating, slow warm-up, and poor heater output. It is a good choice for cooling system maintenance and repair. Replace the thermostat when you service other cooling system parts, and refill the system with the proper coolant after installation.
