CTP offers a wide array of replacement water pumps for Komatsu® engines. Water pumps generally do not require any maintenance, they are a simple in design and should last the life of the engine. However, when a water pump begins to weep excessively, this is a sign that the water seal is failing. Losing coolant in an engine can lead to a catastrophic and costly engine failure.
