Engine overheating (99 Ram Van Wagon 2500 5.2l V8)
Had a huge temp spike. Pulled over and checked both radiator hoses (both were hot). Waited until it cooled down, coolant levels were good. Started it back up, heated to 210°, t-stat opened, cooled down to 180°. Drove it to a friend's house to figure out WTF is going on. Trying to nip this in the bud before I blow a head gasket on my next long trip.
