Coolant Keeps Disappearing?

5

Asked by Sep 11, 2015 at 04:24 PM about the 2001 Dodge Ram 2500 2 Dr SLT Standard Cab LB

Question type: Maintenance & Repair

So I have a 2001 Dodge Ram and it has a little less than 400,000 miles on
it.  I love this truck.  
   Lately though I've been losing coolant for some unknown reason.  It goes
from full to empty between checks!  Yesterday when the truck got really hot I
pulled over and checked the coolant level and it was FULL.  Then the next day
I checked again and it was completely EMPTY... I had not driven during the
nighttime.  
    So what's the deal?  I didn't see any leaks under the truck today.  Any
answers are greatly appreciated.

You should check the freeze plugs. It's quite possible. They do go bad..Good luck.. Are u smelling coolant?

I had this mercury sable that that did the same as yours ever three to four days had to add anti freeze and had no visible leaks or no smoking out of tail pipe so what I did added some alumi seal stop leak. My vehicle did not have a radiator cap just over flow tank with cap. If your vehicle does not have a radiator cap like mine you could add the stop leak to the over flow tank but that would take a couple of days for it to sucked back into the radiator to start working so I removed the top radiator hose when the engine was cold and poured the stop leak directly into the hose and reinstalled had no more problems since then and that was a year before selling vehicle and it was still holding then.

Just because you have never run into that problem before does not mean it has not happened or why would we say that think about Kelly have nothing to prove by lying about something like that.

I go with my answer. Well thats me.I like Kelly. He's probably right. I don't care either way pal. Is your name Kelly? Bang on means that he's right.

Besides. Kelly is talking to me too..Peace

Checked the oil and it wasn't milky, instead it was a dark brown which I think is normal. rv63. I don't smell coolant, and I haven't replaced the freeze plugs in awhile so that could be it.. firebird. Adding stop leak directly to the radiator hose seems risky, at this point I don't want to create more problems, but I'll definitely consider it more down the road if it comes to it. Kelley. How can I tell if the coolant is escaping through the exhaust?

Yeah. If not milky I'd say yes good there. Hey let us know how u fair on this one.. I hope you get this solved. Have a good eve.

I agree with you fully because I was at that point to just got tried of remembering to put anti freeze in so I took that chance and it worked for me but like you said it is your call. Good luck.
