Water pump, and what else?
I did search, didn't really find anything specific to this. I'm coming up on 100K, I've done just about everything else save for the wp and the o2 sensors. I'm thinking water pump first, as it's starting to smell hotter and hotter after each drive, and the needle creeps up a little more and a little faster each time it seems.
So, aside from the pump and likely the thermostat, what else should I do while I'm in there? Does anyone know of a good write up for this procedure with steps, and pics if possible?
Thanks in advance

If the temp is starting to creep up I would have a look at the fan clutch, they do get weak with age.
If you're doing the water pump I would suggest you replace the upper idler pulley while you're there. You can usually only do it when the radiator is out or pushed forward as the bolt for it is too long.

Perfect, thanks. Pelican has a kit with that pulley, the belt tensioner and the belt itself, I'm about to 100K so I might just do the whole kit, water pump and fan clutch at the same time.
