2258019 Gasket-Pump Fits Caterpillar Models

One New Aftermarket Replacement Water Pump Gasket for Caterpillar (Cat) Construction Equipment and Engines

This aftermarket replacement water pump gasket (part number 2258019 / 225-8019) seals the joint between the water pump and the engine block on Caterpillar C-series and 3000-series engines. It prevents coolant from leaking out of the cooling system, helping maintain consistent operating temperature and protecting against overheating and engine damage. Commonly used on a wide range of Cat excavators, backhoe loaders, motor graders, asphalt pavers, and vibratory compactors powered by the 3054, C3.3, C4.4, C6.6, and C7.1 engine families. Also interchanges with Perkins 1103 and 1104 engines.
