DESCRIPTION
The Water Bypass Tube is a component of a truck's cooling system that helps regulate the flow of coolant. Typically made of metal or plastic, this tube connects the engine block to the thermostat housing and allows coolant to bypass the radiator when it is not needed. This helps to maintain optimal operating temperature in the engine, particularly during warm-up periods, and prevent overheating. The Part Number: 4398373 refers to a specific model or version of this component that is designed to fit certain makes and models of trucks.
