2010 Buick LaCrosse Water Pumps

Genuine GM water pumps for the 2010 Buick LaCrosse, at wholesale prices. Factory pumps hold the original impeller design and flow rate the cooling system was calibrated around. Epsilon II from 2010 to 2016 and a lighter redesign from 2017 to 2019.

What sends people here

Coolant seepage at the weep hole or a whine that tracks engine speed. On a full-size car, engine option is the main split here, and it runs deeper into the group than most people expect.

Why buy OEM here

• Real wholesale. The same water pumps your dealer sells, at a fraction over our cost.
• OEM, not lookalike. With water pumps the difference shows up on installation day, not in the photo.
• VIN verified fitment. We confirm the water pumps number against your vehicle before it ships.

Before you order

Buying factory removes the variable. You are installing what the plant installed. We would rather spend two minutes verifying than process a return next week. Orders confirmed before mid-afternoon Central are on a truck that evening.
