My father-in-law passed away, and we bought his 2017 F-250 with 86k miles. From what I know, there’s no issues with the CP4 or turbos, but I’ve noticed a sweet smell coming from the exhaust. At first, it was rare, but now it’s happening every time I run the truck.
I’ve heard that a sweet smell could mean a coolant leak, but my coolant levels seem fine. I even marked the levels with a sharpie for both hot and cold, and they haven’t dropped after a week of driving.
I’ve been monitoring it. Marked the coolant tank levels for both hot and cold with a sharpie, and they’ve stayed the same after a week of driving. That’s why this is so confusing!
Might be worth taking it to a good diesel shop for a check-up. I do that every few oil changes just to catch any potential issues, especially since I tow a lot. A pro might spot something you’re missing.
