Please check notes in each part listing to ensure the A/C Refrigerant Hose is correct for your 1991 GMC SONOMA with a 4.3L 262 engine. FOUR SEASONS & SPECTRA PREMIUM are competing brands, and each brand's A/C Refrigerant Hose may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a A/C Refrigerant Hose fits only certain 1991 GMC SONOMA models.

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

After choosing a A/C Refrigerant Hose, 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 on "Find More Parts", to find more Heat & Air Conditioning parts, other GMC SONOMA parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 1991 GMC will not be lost if you switch.
