Detailed Description

The Motorad UltraStat line focuses on durable thermostat construction and stable coolant control. Part number 5335-180 is a 180°F engine coolant thermostat that matches original equipment temperature requirements for select Hyundai Accent, Kia Magentis, Kia Forte5, Dodge Attitude, and Dodge Verna applications. The stainless steel design supports corrosion resistance, while the valve design is engineered to moderate coolant flow changes and reduce stress on nearby cooling system parts. This part cross-references Stant 46588 and Walker Exhaust 46748 for the same application.

What This Thermostat Helps Address

• Engine running too cool or too warm due to thermostat wear
• Temperature fluctuation from a sticking thermostat
• Cooling system stress caused by abrupt coolant flow changes
• Corrosion-related thermostat failure in service environments
• Air trapped in the cooling system during thermostat service

Installation Notes and Tips

• Confirm the vehicle uses a 180°F engine coolant thermostat before ordering.
• Replace the thermostat only after the engine has fully cooled.
• No gasket or seal is included, so verify the required sealing component for the application.
• Use the jiggle pin weep hole orientation recommended by the vehicle service procedure.
• Inspect the thermostat housing, bypass passage, and coolant condition during installation.

Quality Assurance

Motorad UltraStat thermostats are built with stainless steel construction and valve technology intended to support consistent cooling-system operation. Part number 5335-180 is listed with direct interchange references and confirmed vehicle fitment for select Dodge, Kia, and Hyundai models.
