Buick Regal Water Pump

The Water Pump in the Buick Regal cars is essential in circulating coolant from the car's water tank or radiator to the engine where it absorbs heat created when fuel is burnt. The overwhelming majority of models employ the belt-driven pump with the impeller to circulate the coolant; however, the latest designs often incorporate the electric water pumps. Some signs include, presence of leaks, loud noises coming from the water pump as a result of worn bearings, and high engine temperature due to the water pump's inability to circulate water properly. Performance water pumps that are compatible with high-performance engines are also available and provide many advantages such as higher coolant flow rate, lower power draw as compared to conventional pumps. Some benefits of using an electric water pump include; it facilitates coolant circulation, it cools the engine even after it has been shut down and it can be remoted mounted due to its compact nature.

Each OEM Buick Regal Water Pump we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
