Newbie here. I've been lurking for a few weeks. I bought a 96' 2500 5spd to tow my Jeep to/from events. Interesting to see that Chrysler moved their vaccuum disconnect from the Jeeps to the bigdogs. This weekend I'll be replacing the waterpump and hoses as preventive maintenance. How hard are the valves to set? Is this a good time for the KDP? Anything to watch out for? Where's the best place for to buy a Thermostat?
