If it's red, it's transmission fluid. Coolant would be green. Check the fluid level, don't let it get low, Chrysler minivans are prone to transmission troubles, and low fluid levels over time will ruin a a transmission. And be sure not to overfill, it's just as bad for the trans. Have the leak checked out and repaired, good luck
SOURCE: Heater works but defrost fills inside with fog.
your heater core has probably sprung a leak.does the fog smell kinda sweet?....check the floor in the front where the floor mats are for moisture or even puddles of antifreeze.(the replacement of a heater core can be very expensive as the entire dash usually needs to be removed to access the heater core)also look under the engine near the firewall for antifreeze drips.

Take a good look at the tensioner pulley (the one with the spring) when the van isn't running. You'll notice that the belt is on the very outside edge of the pulley. Once you add water (or hit a puddle) the belt will slip off that pulley. The tensioner arm is worn and needs to be replaced. Since it's worn (the spring has become weak) it's not aligned right and is acting like a cone shaped pulley. As soon as it gets wet it wants to walk off the end.
If you take the belt off there should be a noticable line (paint worn off) on the pulley where it used to ride. Or you can look at it nearest the engine with the belt on and you should see a shiny area where it used to ride.
Hope that helps. Thanks for using FixYa.

It is a continous problem, I ended up changing out the pulleys for grooved ones with a lip ...they have a kit you can have put on it to fix it, but I wouldnt suggest letting Pep Boys do it. They told me about it, but I fixed it myself. I dont understand why Dodge doesnt make this a recall, it happens more often than not and why should we g=have to pay to correct a design problem.
