Product Description

The Gates 42577 Water Pump is a high-quality OE-replacement cooling component engineered for the 2003-2005 Mitsubishi Lancer 2.0 L 4-cyl engine - including the high-performance Evolution VIII, MR, and RS variants where applicable. Built with a robust cast-aluminum housing and a precision stamped-steel impeller, this pump offers reliable coolant circulation, corrosion resistance, and long-life durability, making it ideal for routine maintenance or full engine rebuilds.

As an accessory-belt driven unit, the 42577 integrates directly with the factory belt-drive system, requiring no modification or special timing-belt work. The included gasket ensures proper sealing upon installation. Because each pump undergoes leak and bearing tests before shipping, it provides dependable operation and coolant flow stability under normal and modified driving conditions - a practical choice for enthusiasts and daily drivers alike replacing a worn or failing OEM water pump.
