My father in law just picked up a 99.5 7.3 PS. He was wanting to have general service done and I would like to direct him to a place who knows 7.3s in the Raleigh area. Someone to change the coolant and know (since its not the gold coolant) to put the additive in would be nice. He would also like it scanned (maybe a CC test ect.) to make sure all is well. Any suggestions? Thanks for the help!
