Over time, factory water pumps can suffer from bearing wear, seal deterioration, coolant leaks, and impeller failure. When that happens, coolant flow can become weak or inconsistent, leading to overheating, poor cooling performance, and potentially severe engine damage if not addressed.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eOne of the key advantages of this upgraded version is the \u003cspan class=\"s1\"\u003e\u003cb\u003emetal impeller design\u003c\/b\u003e\u003c\/span\u003e.
