The coolant tank will need removed or sucked out. As far as the t-stat, follow the upper hose to the engine. It will end at the thermostat housing. The t-stat is under the housing. I think the housing is held on by two bolts.
As far as the freeze, make sure you didn't pop any of the freeze plugs. Also, if it froze solid, you may find other problems after it's running again.
