I have a 2006 Ram 2500 with Cummins. The water goes down a bit now and again, and I refill it. Yesterday before hitting the road, I looked, and the reservoir was nearly empty. I filled it.
That water has to be going somewhere, or is if going out the overflow? How often should one have to refill that reservoir, if at all? And do I use antifreeze, 50/50 mix? ??
