Could the problem of white smoke when start up in morning be that the cold start sensor could be at fault


White smoke is actually normal Susan. It isn't smoke, it is steam.

White is steam
blue is oil
black is rich mixture

Gasoline contains water at molecular level, and when it burns it condenses through the cold exhaust system as steam vapour. You should find it disappears when the engine and exhaust is warm.

Is it normal for my truck to smoke on a cold day even after truck has fully warmed up? Not thick smoke light white smoke thought it was suppose to stop after truck warmed up fully


white 'smoke' may be condensation (steam)? Did it do this in the summer as well? Even with a warm engine and hot exhaust the steam will still condense after it leaves the tailpipe on cold days. Your fuel contains water at microscopic level which is vaporised as part of the combustion process.

When I start my car smoke comes out of tail pipe for a few seconds water all so coming out


Water and vapor (steam) coming from the tail pipe is normal and will stop after a few miles when everything is hot. That is one of the reasons exhausts need replacing as they rot with rust and is more evident on cars that only do low mileage as the exhaust does not get hot enough to boil off the water and it sits in the pipe slowly rusting it away. What you see as smoke is probably steam and is more evident on cold mornings. If the car is not using oil then I wouldn't worry.

Suzuki 12valve smokey engine?


Could be valve stem oil seals, could be piston rings worn, could even just need a tune, best advice without seeing the car run is to go to your local mechanic with the car for their opinion

Water dripping out exhaust pipe and engine smoking white smoke


have a compression test as it may be a cracked head. Remember that in cold weather there is steam and condensation coming from the exhaust pipe that is formed from the normal combustion process.

White smoke


from where, end of tail pipe or ?????????????
tail smoke has 2 types,. oil and steam.
1: steam smells sweet(glycol) and goes away fast.
2: oil smoke, smells like burnt oil and takes a vary long time to go byebye.

or is normal.
all cars burning gasoline make water (H2O) as a byproduct, of combustion the seems to go away on a hot day.
but really does not, it just seems to.
on a cold day all cars make steam
if yours is and your neighbors car dont at the SAME time (out door temps same) then your steam is wrong. a bad sign of bad head gasket or far far worse , a cracked head.
did you do the pre fall service, and check antifreeze protection levels.

When we open the freezer door, a lot of steam/smoke comes out. A lesser amount comes out when the fridge door is opened.


If the fridge is working and keeping things cold and frozen, you don't have a refridgerant leak that is producing vapor that might appear as steam or smoke.

The steam/smoke is actually water vapor being made visable due to the temperature difference between the freezer/fridge temperatures and the air temp in the room (or garage) the appliance is in.

It's nothing to worry about and is normally more likely to happen when the outside or house air temp is very warm (Summer months) and when the air is humid.

What's happening is the very cold and cool air is hitting and mixing with the much warmer and much more dense air (humid air contains microscopic water particles) when you open the doors, and is instantly being cooled. Thus it appears as thou the fridge is steaming or smoking.

Have a great day an hope this explains the situation. Best regards.

White smoke or steam coming out of exhaust pipe,


Its funny that everyone has solved the problem without any answers to critical questions. In this case, everyone is right and everyone is wrong. ONLY careful testing and observation will determine if there is an actual problem. I do not solve problems just to be first. Even in a hands-on situation I refuse to jump to conclusions before testing, otherwise you run the risk of at best, "chasing your tail" or at worst, tearing into a perfectly good engine to prove nothing!!!
Happy New Year!!!!
