The reason Regal water pumps are so vital to the life of your car is because they combat the extreme heat of a combustion engine. Water and coolant are pumped through constantly while you drive, and without those liquids, your Regal's engine overheats. A climbing temperature gauge and a puddle of coolant under the motor are primary signs that you need a water pump replacement for Buick Regal. AutoZone carries parts for your car at the right prices, and we also offer a Loan-a-Tool program for easy installation, Same-Day Store Pick-up on online orders and answers to all your tough automotive questions whenever you visit your local store.
