I just did a coolant flush after finding out It had dexcool in it. I replaced it with Zerex G05 and I looked in my radiator a few days ago and to my surprise it was not full after doing the flush around a month ago. My reservoir however was still full. I added some to the radiator and went about my day. I checked today and it was not full again. I have no overheating problems but I want to make sure I’m not causing any problems either. I did not burp the system as I was under the impression TJ’s would automatically burp itself. What could be the case for missing coolant in the radiator? If I need to burp it what steps do I take? Thanks everyone!
