Fitment and Application Details

This Autotecnica thermostat housing assembly, part number HY0720300, is built for vehicles that use an integrated coolant thermostat and water inlet design. It is listed for the Hyundai Tucson and Kia Rondo applications shown above, and the PA66-GF30 housing material supports the demands of engine cooling service. The included gasket or seal helps complete the replacement at the housing interface. This part cross-references Gates CO34940 for the same application.

Common Cooling System Issues

• Coolant leaks at the thermostat housing or inlet connection.
• Overheating caused by a worn thermostat assembly.
• Cracked or heat-aged plastic housing components.
• Service issues when the original seal no longer seats properly.

Installation Notes

Verify the existing housing style, sensor provision, and bleeder screw configuration before installation. HY0720300 is specified without a temperature sensor and without a bleeder screw, so matching the original layout is important for proper fitment. Clean the sealing surfaces thoroughly before assembly and refill the cooling system according to the vehicle service procedure.
