Please check notes in each part listing to ensure the A/C Compressor Clutch is correct for your 1977 PONTIAC GRAND LEMANS with a 4.1L 250 engine. ACDELCO & FOUR SEASONS are competing brands, and each brand's A/C Compressor Clutch may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a A/C Compressor Clutch fits only certain 1977 PONTIAC GRAND LEMANS models.

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

After choosing a A/C Compressor Clutch, 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 Heat & Air Conditioning parts, other PONTIAC GRAND LEMANS parts or parts for a different vehicle.
