    Just messin around in a parking lot one day and tried to pull up & over a curb. I was in 2 wheel drive high, My K5 didn't go anywhere and white smoke with a distinct odor came billowing out from under my truck as I applied gas. Any ideas? Do I need to have my hubs & transfer case engaged for any kind of wheeling?

    White smoke is usually coolant. Did a hose come off? I would hope you don't need to engage 4 wheel drive to get over a curb /forums/images/graemlins/1zhelp.gif

    I think that may be it. I took my truck back out and did some hill climbing & mudding and didn't get the smoke again. After the smoke incident I did notice that my overflow container for the radiator had leaked some coolant out. Although the distinct odor wasn't coolant, it smelled more like the clutch. The clutch was put in about a year ago, shouldn't be sitting there & slipping.

    Did you roast you tires? They will produce white smoke.

    coolant, tires or clutch..... hopefully it wasn't the clutch! Those are the only things in my mind that will create white smoke in a vehicle

    First guess is clutch.If you gassed it before clutch was fully engaged slipping is poss.You would have heard tires spin{left black marks too}Rad hot enough to cause steam wouldn't cool off very quick. /forums/images/graemlins/crazy.gif /forums/images/graemlins/truck.gif /forums/images/graemlins/thumb.gif

    The angle your truck was at probably caused the coolant overflow tank to overflow and spilled onto the engine, producing steam

    my vote is clutch. Both coolant and tires make a smell any backyard mechanic worth his weight in tire rubber should know. When curb popping in a manual you got to let the clutch out slowly and apply gas slowly. When she starts to sound like shes gonna stall then you start apply the gas but like I said just enough so she doesn't stall the whole time. Or get a running start /forums/images/graemlins/smile.gif believe me wailing a curb at 25MPH don't burn the clutch. It makes some metal vs metal noises that are interesting but no smoke.
