Shopping for Auxiliary Water Pump

Auxiliary Water Pump Shopping Info

What Is an Auxiliary Water Pump?

If your car’s heater is having a difficult time keeping your vehicle warm, then a bad auxiliary water pump may be causing the problem. The auxiliary water pump circulates warm coolant throughout your engine’s cooling system to better regulate your car’s temperature during colder days.

How Much Does an Auxiliary Water Pump Replacement Cost?

The cost of an aftermarket auxiliary pump replacement ranges from $40 to $500. The price is affected by the brand of the part and the set or kit inclusions. Replacing the water pump may also cost you an additional $200 to $300 for labor depending on the standard labor rates in your location.

Shop for Aftermarket Auxiliary Water Pumps on CarParts.com
