The thermostat on an engine controls the coolant flow to prevent overheating. Engine overheating or underheating, inconsistent temperature readings, and coolant leaks under the car or near the thermostat housing are all indications of a broken or inoperable thermostat. The thermostat by Volvo Penta (21437904) is a cutting-edge design that uses bleed notches, check valves, and other features to remove air from the system. Stainless steel pistons will function more efficiently and last longer. A brass cap and guide are placed on the motor piston to increase performance. For added strength and durability, the stainless steel spring frame incorporates a channel construction. The engine can operate at its operating temperature because the stainless steel spring has the necessary operating compression.
