Noted trace of oil in radiator overflow. 7.3 non turbo. Could this be caused by cold weather? Have you expirenced this looking for some answers.



Has the anti-cavitation additive been maintained in the cooling system on this vehicle? I hope so, for your sake.

I have had it for a year and when I got the truck had all the fluids and oils changed out at the Dealership. Other than that no. Drove about 6000 miles. Have a brand?

Ouch! You will never know how the coolant was maintained because you don't have the old coolant anymore. Hmmm, I suppose somebody could do a compression test somehow, that's where I'd be going.
