Thermostats

Marine engine thermostats are a crucial component in a boat’s engine system, designed to regulate engine temperature with precision.

Utilizing a sensitive bimetallic coil and a precisely calibrated valve, the thermostats respond to rising coolant temperatures by expanding the coil to open the valve, allowing coolant flow. This mechanism ensures precise control to maintain the optimum operating temperature.

Marine Parts China’s thermostats are tested to meet OEM standards for optimal fit and function, ensuring reliable service life with a manufacturer warranty.

Extensive testing to meet strict OEM specifications for durability, reliability and precise fit, delivering OE-quality function.
500 hours of salt spray testing and over 20,000 open-close cycles.
