Question about 2002 Dodge Caravan
It sounds as if the thermostat is installed correctly --- and it sounds like you have good water flow. what is happening is that when it is cold outside ( single digits ) that when you are driving down the highway, the wind from the outside air plus the fan pull is very cold and is chilling the water in the radiator very fast,, faster then the car is heating it up. I live hear in Alaska and when the outside temperature gets down in the single digits and lower, the heaters here do suffer a bit -- the way that we solve this issue is to obstruct the flow of air through the radiator by installing a radiator ' bra ',, this vinyl piece is installed on the outside grill and has snaps that allow you adjust how much air flow flows through, this bra helps the radiator coolant stay warmer thus giving you more heat at the heater core,, the bra's are not very expensive and they work GREAT,, and as the weather outside warms up you can open the bra up more and more and then remove when spring comes and store for next winter.
here in Alaska there are also people that go to the total extreme and just tape up a piece of cardboard to the radiator ( between the grill and the radiator ) with a small cutout where the fan suction is and this works in the same way. not as nice and pretty as the bra -- but cheap and effective.
this bra idea will fix your heater problem without a doubt.
