I followed a friends advice and checked the fan clutch first. According to an article on flash off road if you turn off the truck and the fan still turns then the clutch is bad. Well I did this test and the fan kept spinning.

I went to the local parts store to get a fan clutch and they didn't have any in their system. I had them pull up a 97 3500 4x4 truck with the 6.5 TD. and they had one. I got the new clutch home and it is the exact same. after the replacement I did the test again and guess what the fan stopped. Looks like this was the problem.
