A water pump protects an engine by circulating coolant to prevent overheating. Cat® Reman Water Pumps are a smart choice when repairing or rebuilding your Cat engine. Our water pumps feature polished stainless-steel shafts that resist corrosion, a durable impeller that provides excellent coolant flow, and hardened bearing retainers to improve bearing retention. Each unit features 100% replacement of bearings, and improved oil and coolant seals to help provide longer life. Every water pump is tested to the same precise Caterpillar standards as new parts, to ensure reliability that even the best reverse engineered aftermarket brands can’t beat. They provide immediate, off-the-shelf availability with a same-as-new warranty. You’ll get the best wear life, fuel economy and overall performance, regardless of the equipment it’s powering or the conditions it has to endure. And because you’re leveraging the ‘second life’ built into every Cat diesel engine part, they cost a fraction of new.
