Product Details

What It Helps Address

• Engine running too cool or too hot due to thermostat control issues
• Coolant leaks at the thermostat housing or seal interface
• Air trapped in the cooling system after service
• Delayed coolant temperature regulation during warm-up
• OE-style replacement needs for Hyundai Genesis, Hyundai Equus, and Kia Borrego

Installation Notes and Tips

Verify the original thermostat temperature, outlet configuration, and housing shape before installation. Clean the mating surfaces thoroughly and inspect the coolant passages, seal seat, and mounting points for corrosion or debris. Because bolts and mounting hardware are not included, reuse or replace fasteners as required by the vehicle service procedure. Bleeding the cooling system after installation helps remove trapped air and supports stable temperature control.

Quality Assurance

Manufactured by an OE supplier using OEM-quality materials and OE specifications, the Motorad 933-180 is built to meet factory-style cooling system requirements for the listed Hyundai and Kia applications.
