What does coolant bypass hose do?
The bypass feature allows water to flow around the engine, without passing through the radiator, while the thermostat is shut. Without it, the water will not circulate correctly creating hot spots around the engine which could lead to damage.
Is water pump connected to coolant?
What Is a Car’s Water Pump? The water pump is the heart of your car’s cooling system. It pumps coolant through the engine to keep it from overheating. A water pump doesn’t move water alone; it controls the flow of coolant through your engine, and the coolant is usually a blend of water and antifreeze.

How does a coolant bypass valve work?
Most engines have a small coolant bypass passage that permits some coolant to circulate within the cylinder block and head when the engine is cold and the thermostat is closed.
