hello, I have a 97 blazer with 196kmile (on engine). here in illinois,
we have some teen temperatures lately and I notice, the car puts white
smoke all the time, hot or cold. Most of the cars puts out white before
they heat up but mine does all the time. 91 GMC safari with 4.3 Z
engine does not smoke that much even it has 160 F thermostat. Do you
have any idea whta might be the reason, or first what i should check.
White mist coming out of your tail pipe might be antifreeze. Check the
level in the radiator. Have the cooling system pressure tested, you may
have a blown head gasket.

But they aren't particularly known for head gasket problems.
It's cold, probably just water vapor. A lot of cars will put out
what appears to be white smoke (water vapor) even once they
are warmed up.
It got 50s and the white smoke dissappeared. what botters me is, It
smokes white even when the engine is hot. independent of how long i
drive, it just smokes white when it is cold. My other cars smoke white
for a short time
Different cars do different things. I would not worry about it. Have
you taken a whiff of the exhaust itself? If it was burning antifreeze,
you should be able to smell it. And if it was burning antifreeze, it
would smoke hot or cold, no matter what the temp was.
If your coolant level is high enough and you haven't added any it
could just be that it's too cold outside. In some parts of Canada in
the winter virtually every car is puffing white smoke.
See if it smokes when it's warm outside. If not, might just be
typical cold weather "smoke."
