My vehicle: '02, 4.7L V-8, 2WD, ABS brakes, automatic transmission. Current mileage…about 58k. This truck has not seen hard use like trailer pulling. I've changed the oil/oil filter and air filter regularly and replaced the front brake pads. Also cleaned the MAF and throttle body about every 10k. I know that the timing belt is due for replacement at 90k, and I know that the parking beak needs adjustment. The location is Kansas, so it gets cold in the winter, so that's a consideration. What else?

Replace the serpentine belt because of age?
Flush transmission or just drain and replace fluid?
Flush radiator? Replace radiator cap?
Drain and replace differential oil?

I've owned the truck since it was new. It runs fine….just want to keep it that way.
