Mack Engine Water Pump Kit

The Mack Engine Water Pump Kit is a complete OEM replacement solution for MP7 and MP8 engines experiencing coolant loss, overheating, or reduced cooling efficiency. When the original pump begins to wear, internal seal degradation and impeller erosion can disrupt coolant flow and create uneven temperature distribution across the engine. This kit restores proper circulation using a precision-cast impeller designed to maintain stable flow at idle, sustained highway speeds, and under load, helping prevent hot spots that contribute to head gasket stress and premature component failure. Mack supplies all required high-temperature gaskets and O-rings to ensure correct sealing against the engine block, eliminating the guesswork that often leads to repeat leaks. Because the bearing and seal assemblies are engineered specifically for heavy-duty accessory drive loads, the Mack 85023996 kit delivers predictable service life and cooling performance that generic aftermarket pumps often fail to match.
