NEW FAN CLUTCH CHEVROLET fits T6500 T7500 and T8500 with 7.8L Duramax Isuzu inline 6 cylinder diesel.   300hp.
2007-2009. Isuzu part #8-98075-123-0 and gm part # 98075123. Some customers said have used in place of or interchanged with AC Delco part #15-40025 but I am not sure and please email with measurements if you have this part #. Gm also says this replaces part # 98065838.  Make sure this is the right part. Research Your part before purchasing this part. Be sure this is correct part by pics etc.  I can take any measurement needed.  My information on this is from research only. From what i found this fits GMC and Chevy T6500 and T7500 trucks 2007 to 2009 and Isuzu cab forward trucks of same year. It is for the 7.8 liter isuzu or duramax in line six cylinder engine but this is only what info i found and may not be correct or fit all models. I will not guarantee this is part you need. Feel free to ask any questions before buying. Please match by pics and ask and we can get any pics or measurements you need. I bought these new out of Gm plant when Gm stopped making medium duty trucks. Thanks for looking. Check out our Ebay store for other parts.  Again please send pics and measurements of your clutch or ask for mine so we can compare before purchase.  No returns on this item.
