Because it’s run directly from the engine, if you’re at idle, the pump is running slower, and your coolant is flowing slower, so your engine temperature will go up slightly. At freeway speeds, when your car is running at 3K RPM, it’s working fastest, helping to funnel heat safely away from the engine and into the radiator.
