What This Thermostat Helps Address

• Engine running too cool or too warm due to thermostat wear
• Delayed coolant circulation after cold starts
• Temperature fluctuation in the cooling system
• Cooling system service on Mazda Miata, Mazda Protege, Mazda MX-3, Mazda 323, and Kia Sportage applications
• Replacement of a thermostat specified for 192F operation

Installation Notes and Tips

Verify the OE temperature specification before installation and confirm housing dimensions match the application. The jiggle pin weep hole helps with air relief during filling, and the offset design should be oriented to match the original thermostat layout. Because no gasket or seal is included, reuse only if the existing seal is serviceable or install the correct replacement seal for the vehicle.
