Sierra Marine Engine Parts - 18-3626 Thermostat Kit - (118-3626) Sea Star Solutions The thermostat prevents cooling water from reaching the cylinder walls until sufficient heat is present for effective combustion. The thermostat permits cooling water to flow from the water pump via the water jacket and out the exhaust after the cylinder temperature has reached a certain level. A thermostat is meant to keep the cooling water in the block at the temperature specified by the engine manufacturer. This is usually 145° (63 C) degrees Celsius. It then opens to allow the water to escape before it becomes too hot and overheats the outboard. It must prevent coolant from flowing to the radiator until the engine has reached operating temperature. High-temperature readings and overheated engines; low-temperature readings and underheated engines; temperature fluctuations; and coolant leaks around the thermostat housing or under the engine are all symptoms of a faulty thermostat. This product replaces 47-3626, 808282272036. Key Features: A professional, high-quality OE style replacement thermostat exceeds all original equipment performance. It separates the engine from the radiator until a particular minimum temperature. It's built inside the engine block and controls the flow of the coolant to the radiator.
