Description
The ACDelco ACWP45013 Water Pump Kit (GM 19281682) provides reliable coolant circulation throughout the engine cooling system for Holden Colorado and Trailblazer models equipped with the 2.8L Duramax LWN diesel engine.
The water pump is responsible for circulating coolant through the engine, radiator and heater system to maintain optimal operating temperature. A worn or leaking pump can lead to overheating, coolant loss, and potential engine damage.
