Suzuki DF70A-DF300 Thermostat (71°C) 17670-90J11

The Suzuki Thermostat 17670-90J11 is a genuine Suzuki OEM 71°C (160°F) water thermostat used on a wide range of Suzuki four-stroke outboards. It regulates cooling-water flow based on engine temperature, helping the engine reach and maintain its proper operating temperature.

This thermostat appears in Suzuki cooling systems that may also use a separate 60°C thermostat, depending on the engine and thermostat location. The correct thermostat should therefore be verified by engine model and serial number before replacement.
