Hi, It is Dan. I will try to help. Possible causes of your overheating are thermostat, water pump, restrictions of flow in the cooling system of both air or coolant, Fan hub or slipping belts. Have you replaced the thermostat?

Customer: replied 1 year ago.
I haven't replaced the thermostat yet. The truck doesn't get much use anymore and sits on the farm sometimes for months at a time. I am wondering if there is a way to "hotwire" the at cooling fan to see if it is working of it there is some other way to see if the fan is working?
Customer: replied 1 year ago.
Where is the thermostat located? I will try to check it out.
