Why is there a water leak at water pump area only during stops of Mitsubishi lancer 1997 model?

A water leak at the water pump area of a 1997 Mitsubishi Lancer during stops may indicate a failing water pump seal or gasket that only manifests under certain pressure conditions. When the engine is running, the pump's operation may temporarily seal the leak, but when the engine stops, pressure changes can cause coolant to escape. Additionally, a small crack in the pump casing or a loose hose connection could also lead to leaks when the system is not under pressure. It's advisable to inspect the water pump and surrounding components to identify and address the issue.
