Van is over heating and then cools down on it's own think it's the thermostat. The water resovour is always low on water but it might be boiling out.
Where the top radiator hose goes to the engine its under that housing on the intake

heating and cooling fans are generally one and the same. changing freon doesn't always fix the problem... did you have the system pressure checked for leaks first.
Second determine if the vents are opening properly (switching from heat to cooling) basically when you change to cool it closes air access to the heater core.

check the coolant level. b-4 you start vehicle in morning, open radiator cap then start vehicle if level drops add until full then replace cap.

SOURCE: 2005 Dodge caravan is overheating, but there is no
Overheating can be caused through a lot of things But 1st on the heater pipe going into the cab ,through the firewall there is 2 heater pipes 1of them has a air valve on it so when you turn to hot the vacuum opens the valve and lets the hot water come through.or it could be under the dash on inside of firewall by heater inlet.BUT check your radiator for dust and dirt in the outer cores/Loose fan balt/water pump falty/Head gasket leaking/ plus others will all cause
the car to overheat .
So let me know how you get on Ron

Replace the bad radiator hose first. Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator. Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it. Fourth- Check for leaks by looking for the colored dye. If it's not the radiator hose, then could possibly be a pin hole in your radiator. Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

Nice design Dodge.. NOT! Looks like I'll have to drop motor to get to thermo. That's not going to happen! Any other ideas on how to loosen up sticky thermostat.
