Thermostat - Sierra Marine Engine Parts - 18-3637 (118-3637)

The thermostat in an engine regulates the engine's temperature by controlling coolant flow. High heat temperature readings and overheated engines, low-temperature readings and underheated engines, temperature fluctuating erratically, coolant leaks around the thermostat housing or under-vehicle are all signs of a damaged or failed thermostat. Sierra Marine Engine Parts (18-3637) Thermostat is a highly advanced design that bleeds air out of the system via bleed notches, check valves, and other features. Use stainless steel pistons for longer life and more efficient functioning. For more efficient operation, heat the motor piston brass cover and guide. The spring structure is made of stainless steel and has a channel construction for further strength and durability. The stainless steel spring provides precise operating compression, allowing the engine to quickly reach its operating temperature. The right engine cooling temperature ensures maximum performance and efficiency. Fits for Yamaha VF200LA/VF225LA/VF250LA (2011-18) Cross References Yamaha Outboard 6CB-12411-10-00.
