2007 Dodge Ram 2500 with the 5.7 Hemi 181k miles, its truck at work and the water pump started leaking badly, they have to add coolant every day. I just have two questions, what size is the fan nut and is it clockwise to loosen or counterclockwise? Also, what are the torque specs for the pump bolts? I looked online and got answers of 20 ft lbs and 30 ft lbs, I just want to be sure. Thanks
