I liked the 4.7 until I found out that by the time the check gauges light comes on, it is too late. My Dakota is sitting in the driveway with a blown motor. This all-aluminum engine is VERY prone to overheating, which will quickly ruin it. Turns out the water pump is very fragile too. Not sure whether the water pump or the head gasket went first. This is with only 76,000 miles on it. Suggest carefully looking at the 5.9 engine, even though it has a little less power and less mileage.
