A friend has this truck and its blowing out white smoke from the exhaust as it says above and he was wondering what that could be? It sounds like water to me but he says it should be black. So I thought I would ask to see what you guys think. I don't know if he is having any other problems with it like loss of power but I am texting him now to get an answer.
General rule:
black = excess fuel blue = oil white = coolant
White smoke from a diesel can also indicate low engine temperature.....the smell is indicator. If it smells like unburned diesel it's likely due to this. White smoke due to steam from coolant in combustion chamber has a distinctive glycol/exhaust aroma.
Fair enough, but coolant would not cause balck as suggested.
