Do not forget to inspect the heater hoses . If they are original , they may be getting to the age where it is prudent to replace ( preventive maintenance ) . You can loose a lot of coolant if one cracks & springs a leak . Not a high dollar part to replace .
Did you say you checked belts and windshield wiper blades ?
Fuel filters ?
Condition of the radiator ?
Does it have an external transmission / supplemental cooler ?
God bless

The truck actually looked like that when I bought it - dark blue, debadged, 5 or 10% limo tint all around. Buddy of mine works with the Secret Service, and he laughs because whenever the President comes into town, he has four or five trucks just like mine show up in his parking lot.
Thanks again!
