White and gray smoke coming out back and underneath 1995 Chevy Bl
I have a 1995 Chevy S-10 Blazer. Bought it new and it's given me so many problems. Today the check engine light came on, the guage for water temp was wavering and it started smoking. My son was driving it and by the time he got home there was gray smoke coming out from underneath and white smoke all around the car, he said it was coming from the exhaust, but there was so much of it. Both my son and daughter in law smelled antifreeze.What are all the things I should have checked.

Re: White and gray smoke coming out back and underneath...
Too late to check now... you've got a blown head gasket. When the gauge starts to give you any indication that something's not right you must shut it down or this kind of thing happens. Could have started as a bad water pump, hose etc. With low coolant from that (or anything else) continued operation will kill the whole thing!...Sorry!!

Sometimes the A/C drips water condensate onto hot exhaust pipes and you will see steam. Depends on outside humidity, whether you are using the A/C, and evaporation.
White smoke from exhaust can be a sign of a water leak in the block. You will get some vapor depending on outside air temps and moisture in the fuel. The new Ethanol mix attracts moisture more than the old gas did.
You can benefit from a pressure test of the cooling system. Under normal conditions, it takes awhile for pressure to build in the radiator. This would coincide with the 15 minutes you mention for your problem to begin.
Is it gray, bluish gray, or white? White smoke, during warm weather, indicates that you have a head gasket out and it's vaporizing water, it will look much like it does when you first start it on a cold day. Bluish gray indicates burning oil, which could be bad valve seating, severe engine wear on your piston rings and oil is blowing past them into the combustion chamber. Grey smoke is probably water as well, though it could be contaminated with oil, or the vehicle could be running too rich, getting too much gasoline. But typically this is more of a black smoke than gray.
White smoke means there's water or coolant mixing in with your fuel. Could mean a blown head gasket or intake manifold.The more you drive it like this, the more expensive the damage will be to repair.
As you have already changed the regulator and checked sensor the above can be a problem please check
A puff of smoke when you start up indicates worn valve seals.That's why all your work didn't fix the problem and it doesn't show a code. It's a pain in the --- job that requires some specialized tools so I guess it depends on how bad it bugs you,if oyu want to fix it.
