Product Details
Bosch is known for making reliable automotive parts, and this 10W electric water pump is built to match the original equipment specifications for your 2004-2006 Chevrolet Silverado 1500. If your current water pump is leaking or not circulating coolant effectively, this new unit will get your cooling system back in order.
This water pump is 100% new and undergoes rigorous testing to ensure it works right out of the box. Each pump is vacuum leak tested to catch any potential leaks from the housing, seals, or plugs. They also perform torque testing on the impeller and shaft connection to make sure it's secure. Bosch uses original equipment mating parts and accessories during testing to confirm it will fit correctly, though you'll want to reuse your original isolator grommet and bracket if they are still in good condition.
