Review AFTERMARKET Replacement Fit Yanmar Series 100 Thermoswitch 12013091370 fits JH

The Yanmar JH Thermoswitch 120130-91370 is a crucial component for the efficient operation of Yanmar marine diesel engines. This thermoswitch is designed to monitor engine coolant temperature and regulate various engine functions based on that temperature.

The thermoswitch is built with a robust and durable construction, featuring a high-temperature resistant sensing element. It is designed to withstand the harsh marine environment, ensuring reliable performance even in extreme conditions. The switch housing is made of corrosion-resistant material, protecting the internal components from the damaging effects of saltwater and sunlight.

The thermoswitch operates by sensing the coolant temperature and sending an electrical signal to the engine control system. When the coolant temperature drops below a certain threshold, the switch activates the engine's heater to maintain optimal operating temperature. Conversely, when the coolant temperature rises above a certain threshold, the switch deactivates the heater to prevent overheating.

The Yanmar JH Thermoswitch 120130-91370 is easy to install, with clear instructions provided in the user manual. It is compatible with a wide range of Yanmar marine diesel engines, including those with serial numbers starting with JH, JH2, JH3, and JH4.

This thermoswitch is essential for ensuring the longevity and optimal performance of your Yanmar marine diesel engine. It helps prevent damage caused by overheating or freezing, protecting your investment and ensuring safe and reliable operation of your boat or other marine vessel.

In summary, the Yanmar JH Thermoswitch 120130-91370 is a high-quality, durable component designed to monitor engine coolant temperature and regulate various engine functions to maintain optimal operating conditions. Its robust construction, ease of installation, and compatibility with a wide range of Yanmar marine diesel engines make it an essential addition to your boat or marine vessel.
