2002 town & country overheating

First thing to check on these vehicles, open the hood look at and feel the hood insulation cover is it damp or wet? LH on the drivers side..

Not it is not wet.

Double check for leaks, be sure to check the rear passenger side (Tire area) if the vehicle has the rear heater. Was the van driven when overheated? If yes the the coolant needs to checked for C02 Carbon Monoxide, a combustion by-product chemically test it. If it has NOT been driven while overheating, have the coolant system pressure tested to determine where the loss of coolant is originating from. You need find out where!
