Sierra Raw Water Thermostat 18-3615, 150 Degree F, White, Volvo Penta Applications

The Sierra 18-3615 is a raw water thermostat designed to regulate engine cooling temperature in marine raw water cooling systems. Set to open at 150 degrees F (66 degrees C), it maintains consistent engine operating temperature by controlling the flow of raw water through the cooling circuit, helping protect the engine from overheating and from running too cool for efficient combustion. The thermostat is finished in white and is built to meet or exceed the specifications of the original equipment part it replaces. It is intended for raw water temperature control on Volvo Penta applications. Sierra manufactures replacement parts that supply many OEM engine manufacturers and boat builders, and the 18-3615 is produced to the same fit, form, and function standards as those OEM components. This thermostat is a straightforward maintenance replacement item for boat owners servicing their raw water cooling system, and it is backed by Sierra's standard limited warranty on parts purchased for marine engine upkeep.
