Detailed Description

This engine coolant thermostat housing is designed for Hyundai Santa Fe, Tucson, Sonata, Santa Fe Sport, and Kia Optima, Sportage, and Sorento applications listed above.

Installation Notes and Tips

Verify the housing shape, port layout, and 30-degree neck angle against the original part before installation.

Inspect the mating surfaces, hose connections, and nearby coolant lines for wear or residue before reassembly.
