Detailed Product Description

Motorad Standard part number 240-160 is an engine coolant thermostat engineered to meet OEM specifications for fit and thermal performance. The 160-degree design opens at a lower temperature than standard factory thermostats, making it a practical replacement when restoring cooling system operation on vehicles such as Mazda Miata, Kia Rio, Suzuki Vitara, and Dodge Caravan applications. Its copper case and wax compound are selected to provide quick, consistent reaction to coolant temperature changes, while the offset design and air relief valve support proper installation and system bleeding.

This thermostat is built for broad coverage across many Chrysler, Dodge, Ford, Honda, Hyundai, Kia, Mazda, Mitsubishi, Plymouth, Suzuki, and Toyota models listed in the fitment data. It is a service part for drivers addressing cooling system maintenance on vehicles ranging from 1967-2018 model years.

What It Helps Address

• Engine running hotter than expected due to a worn thermostat
• Slow warm-up or unstable coolant temperature control
• Cooling system service on high-mileage vehicles with aging thermostat components
• Temperature fluctuation caused by a thermostat that no longer opens consistently
• Air trapped in the cooling system after thermostat replacement

Installation Notes and Tips

Verify the thermostat temperature rating and flange dimensions before installation. This part does not include a gasket or seal, and no installation tool is included. Use the correct OEM-style seal or gasket for the specific vehicle application where required, and inspect the housing, mating surfaces, and coolant condition during service. The jiggle pin weep hole should be oriented to assist with air relief during installation.

Fitment examples include 2001-2005 Mazda Miata, 2004-2005 Kia Rio, 1999-2001 Suzuki Vitara, and 1984-2000 Dodge Caravan. Confirm the exact engine application against the vehicle catalog before ordering.
