97 blazer 4.3 has white exhause fume
Question:
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.
Response:
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.

Response:
Those blazers are known for cooling system problems, so Harryface is probably correct.

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."

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. Ian
Response:
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 – Hide quoted text — Show quoted text -> Those blazers are known for cooling system problems, so Harryface is > probably correct. > But they aren’t particularly known for head gasket problems. > It’s cold, probably just water vapor.

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. Ian
Response:
No funny smell. everything looks ok. thanks for the input – Hide quoted text — Show quoted text -> 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.
