What is Included
The 13345 Thermostat Kit is intended to simplify thermostat service on compatible Evinrude E-TEC G2 engines.
The thermostat system uses the components shown above, including the thermostat, thermostat gasket, thermostat cap O-ring, thermostat cover and spring. Verify the exact contents of the 13345 package shown on the product listing before ordering any individual components separately.
Why Replace the Thermostat?
The thermostat regulates coolant flow through the engine so the powerhead reaches and maintains the correct operating temperature.
A thermostat that sticks open can cause the engine to operate too cool, while a thermostat that sticks closed or does not open correctly can contribute to elevated engine temperature or overheating.
Common Reasons for Thermostat Service
- Routine cooling-system maintenance
- Engine running hotter than normal
- Engine running cooler than expected
- Thermostat sticking or corroded
- Salt or mineral buildup around the thermostat housing
- Cooling-system inspection during major engine service
- Damaged thermostat gasket or O-ring
- Thermostat housing opened for inspection or repair
Inspect the Complete Thermostat Assembly
When the thermostat housing is opened, inspect more than just the thermostat. The gasket, cap O-ring, spring and thermostat cover should also be checked for wear, corrosion, damage or deterioration.
Replacing damaged sealing components during thermostat service can help prevent coolant leaks and avoid reopening the housing for a minor seal failure later.
