Please check notes in each part listing to ensure the Radiator Fan Switch is correct for your 1986 GMC K1500 PICKUP with a 6.2L 379 DIESEL engine. ACDELCO & FOUR SEASONS are competing brands, and each brand's Radiator Fan Switch may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Radiator Fan Switch fits only certain 1986 GMC K1500 PICKUP models.
Clicking a "More Info" link will display a picture and/or other details about that Radiator Fan Switch in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Radiator Fan Switch, 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 Electrical-Switch & Relay parts, other GMC K1500 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 1986 GMC will not be lost if you switch.
