Proper maintenance of your Chevy Silverado’s water pump ensures a well functioning cooling system for best engine performance. Leaks on your engine’s water pump can easily lead to overheating causing serious damage to your truck’s engine.
If your water pump is failing, here are simple steps you can easily follow on how to replace a water pump in a Chevy Silverado and save yourself from spending so much on major engine repairs.

- Disengage all engine parts attached to the water pump with the use of an adjustable wrench which include the ducts, hose, fan, clutch, and belt.

- Once the water pump is properly positioned, tighten the bolts. Reattach the engine parts securely to the water pump. Replace parts like a leaking hose with new ones to maximize engine performance.
- With everything in place, reconnect the drain plug to the radiator and fill the latter with coolant before you rejoin the negative cable to the battery.
