Hmm I'll inspect further.
Yes, thank you Bonnie6G - I was going to say the same thing. I worked at the assembly plant for the Navistar (International Trucks) several yrs ago. We also built the 7.3 powerstroke for Ford.
Two of the key things we would get dealer claim notices on during PDI were low coolant level/air in system and also the AC refrigerant being low. The dealer should be able to check the coolant level, and if needed, add more or "burp" the system to get the air out. You could do it yourself, but on a brand new vehicle under warranty, I would let the dealer check it out. Plus, bringing it to the dealer, they log and report all claims to Ford. This info is then fed back to the engineers and quality teams at the respective assembly plants. So by letting your dealer know, you are not only fixing the issue for yourself, but also giving the Ford guys a heads up to watch for this issue on future built Broncos.
