11 years old I would replace the water pump before the cooling system service just as cheap insurance. It's all going to be torn apart anyway for the cooling system service, this will be a most opportune time to pull the pump.
If the battery is more than 3 years old, i'd pitch it and get a new DIEHARD from Sears.
Replace battery cables if they need it.
Sears will install it & test your charging system for free when you buy a new battery.
Starter. If it gives you any trouble, any at all, even a funny sound, i'd pitch it too. It would be a drag to do all the above, have a new battery & the starter quit & left you sitting way back in the forest! Remember, it too is most likely 11 years old.
Do a major engine tune up :
>cap
>rotor
>plugs
>wires. Buy the best (most expensive) set of spark plug wires you can afford. You want them to not short when you get them wet 30 miles of pavement. All dielectic grease to all the connectors
>Set the timing & put some fuel system cleaner in the tank a couple of tankfuls.
WHY ?
You need to make this truck robust for off road fun. Ain't nuthin I hate more than a trailside breakdown. When I hit the trail I wanna W H E E L not twist wrenches. So I do that in my driveway at my convenience.
Remember :
AAA does not offer trail service.
I hope this helps...
