Coolant seepage at the weep hole or a whine that tracks engine speed. On a heavy duty pickup, trim, tow package and drivetrain each move part numbers within one model year.

What you get ordering from us

• Factory sourced. These water pumps are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical water pumps numbers for you.
• Ships from Dallas. Water Pumps ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on water pumps that did not fit.

Making sure it fits

Aftermarket versions are often close enough to install and far enough off to cause a repeat repair. Option packages divide this catalog more than model years do. Send the VIN and skip the problem. Our Dallas location means most of the country is inside a two or three day ground window.
