beco822 Posted August 2, 2019 Share Posted August 2, 2019 (edited) 2005 Mack Granite Couple days ago at the end of the day I noticed the fan clutch engaged as it should.Problem is it will not shut off.From what I understand there are 4-5 sensors that make this happen.Truck is showing no check engine lights.Any ideas where to start?

Golddog Posted April 4, 2020 Share Posted April 4, 2020 Did you ever get this figured out? My 01 rd is doing the same thing and I’m having no luck figuring it out.
