Troubleshooting & FAQ

How do I know if my thermostat may be failing?

Possible symptoms include overheating, an engine that runs too cool, inconsistent temperature behavior, or abnormal temperature-gauge readings. Diagnosis should include inspection of the thermostat and the complete cooling system.

What is the specified thermostat temperature?

The supplier specification for this application is 130°F (54°C). Do not substitute a different temperature rating unless it is specifically approved for your engine.

Is this an OEM thermostat?

What should I verify before purchase?

Verify the engine brand, exact model, horsepower, year, 2-stroke configuration, thermostat angle and flow application, and the reference number on the original part. If any of these details differ, consult the engine service information before ordering.
