So I'm driving along in -20 F cold, my three kids and wife in the car, and we get a strong antifreeze smell. Then the heat stops working. I keep an eye on the engine temp and, because of the extreme cold, no overheating. So I get home, pop the hood: no coolant. I pour in some antifreeze, only to see it come gushing out from a hole in the line that goes back to the rear A/C. When I take it to the mechanic, know what he says? "We see a lot of corroded coolant lines on these Grand Caravans." What a surprise. So instead of paying $300 bucks to replace the line, they put in a non-corrosive flexible heating hose for $95. What team of morons engineered these Caravans?
