Description and Purpose

The International / Navistar® Cooling System Solenoid Valve is a vital component of the cooling system in heavy-duty vehicles. It controls the flow of coolant to the cooling fan system, ensuring proper engine temperature reggulation. By managing the fan clutch’s operation, it optimizes engine cooling efficiency and reduces wear on the system. This solenoid valve plays a crucial role in maintaining the vehicle’s performance and preventing engine overheating.

Why Replacement is Important

A malfunctioning cooling system solenoid valve can cause irregular fan operation, leading to engine overheating, reduced cooling eficiency, and potential engine damage. Replacing a faulty solenoid valve ensures that the cooling system operates as intended, maintaining optimal temperatures and preventing costly repairs. Timely replacement helps extend the life of the engine and other vital components.
