hey all
I have a 1999 ram 2500 4x4 with the v10 and its been starting to have some issues lately,It has about 270000kms on it.So it has always used a bit of coolant but I cannot for the life of me figure out where it is going.No signs of external leaks,nothing on the grouns under the truck ever but about every 2 weeks the coolant reservoir is empty and needs to be filled,Now yesterday I went for a drive into the city and we've been in the middle of a month long cold snap in my parts.So drive the 30 miles into the city,no issues,heat is ok,its never been great in this truck.Temp,oil pressure,etc all normal.Stop at the first light and all of a sudden the air coming out the vents goes cold cold,temp gauge starts to climb,Start driving,temp gauge goes up to just over half then suddenly back down to normal,I pulled into the nearest gas station and parked and shut it off.Went inside bought a gallon jug of premix antifreeze.reservoir was empty.Filled it about halfway.Let the truck sit for about ten minutes,opened the rad cap,wasn't hot at all.Radiator was down about an inch and a half so topped it up.Drove the rest of the way to my destination.no issues,parked for a few hours.Came back out popped hood,reservoir was empty again,rad full.Checked the oil.all good no signs of contamination.Filled the reservoir up again and drove home,took it easy but 60 mph drive for about an hour,gauges normal,temp down a bit from normal but driving in minus 20 temps.Made it home ok,this morning checked again reservoir empty again,oil seems fine,no signs of leak or drips on ground.A little baffled at this point.
