Hi
White smoke
is caused by water and or antifreeze entering the cylinder, and the engine
trying to burn it with the fuel. The white smoke is steam. There are special
gaskets (head gaskets are the primary gaskets) that keep the antifreeze from
entering the cylinder area. The cylinder is where the fuel and air mixture are
being compressed and burned. Any amount of antifreeze that enters this area
will produce a white steam that will be present at the tailpipe area. If white
smoke is present, check to see if the proper amount of antifreeze is inside the
radiator and the overflow bottle. Also check to see if antifreeze has
contaminated the engine oil. You can look at the engine oil dipstick, or look
at the underside of the engine oil filler cap. If the oil is contaminated with
antifreeze, it will have the appearance of a chocolate milkshake. Do not start
the engine if the oil is contaminated with antifreeze, as serious internal
engine damage can result. How did antifreeze get in the oil or cylinder in the
first place? The engine probably overheated and a head gasket failed due to
excessive heat, thus allowing antifreeze to enter the cylinder (Where it is not
meant to be).
So these
are the things if white smoke is present;
• Check to see if the proper amount of antifreeze is inside the radiator and
the overflow bottle.
• Check to see if antifreeze has contaminated the engine oil.
• Look at the engine oil dipstick, or look at the underside of the engine oil
filler cap. If the oil is contaminated with antifreeze, it will have the
appearance of a chocolate milkshake.
• Do not start the engine if the oil is contaminated with antifreeze, as
serious internal engine damage will likely result.
