Hey guys, I just got my oil changed on my 07 1500 hemi today and the guy showed me that my coolant was over a half gallon low since my last oil change at the same place. Truck has 51,xxx miles on it. I drive a lot of highway miles for work but I doubt that has anything to do with it. Where is my coolant going? I'm very easy on the truck, nothing is dripping or leaking around any seals and the truck isnt smoking or anything out of the tailpipe. Any suggestions, this kinda concerns me. Thanks.

 

Change the radiator cap.

 

I had a similar problem. I noticed that my coolant was disappearing. On the coolant reservoir over the radiator is where I noticed that the fluid was continuing to get lower and lower. My shops checked and checked. No visible leaks nothing on the ground. It somehow ended up beeing a faulty water pump. Replaced and everything is fine now.

I had the same problem with the water pump. It was such a slow leak it only leaked while driving. Changed water pump, problem was sovled.

 

I know Dodges are known for the mystery coolant loss...I put about 1/2 gal every few months

 

As said above, you either have to be losing it somehow or using it internally.
