Please check notes in each part listing to ensure the Water Pump Gasket is correct for your 1984 GMC K2500 PICKUP with a 6.2L 379 DIESEL engine. ACDELCO & VICTOR REINZ are competing brands, and each brand's Water Pump Gasket may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Water Pump Gasket fits only certain 1984 GMC K2500 PICKUP models.

Clicking a "More Info" link will display a picture and/or other details about that Water Pump Gasket in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Water Pump Gasket, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Cooling System parts, other GMC K2500 PICKUP parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1984 GMC will not be lost if you switch.
