Hi. I have a 19 ram 1500 with the 5.7l only 37k miles. Had the over temperature light come on pulling in my driveway. Found it low on coolant so I added distilled water to fill. It will idel and hold temperature but i found a drip coming off the back of cylinder 7 at the head gasket. Unsure if there is a coolant line above it under the intake manifold leaking down or my head gasket. Warrenty expired a few months ago and the dealer isn't willing to help. Any guesses from this photo?
