Water Pump Shopping Info

What Is a Water Pump?

The water pump is a component that allows coolant to circulate from the radiator to the engine, letting the fluid absorb the heat produced by the latter as the vehicle speeds up. It is typically installed with the radiator and cooling fan assembly.

How Much Does a Water Pump Replacement Cost?

A new water pump can cost anywhere between $20 and $400, depending on factors like your vehicle’s specifications, the water pump’s finish, material, pulley inclusion options, etc. Labor costs for a water pump replacement typically range from $250 to $350 excluding other fees like taxes.
