    Ok so what you are saying is that I have a bad head gasket somewhere in the engine? The problem is not cheap to repair? May I ask so things that might cause this to happen? My car was brand new when I purchased it, It was purchased in August of 2003!!!!

I have a 200 kia sportage it wouldnt start so i got a jump and it started but there was white smoke coming from my muffler it stopped but my radiator was bad so i replaced it was running ok , then the next...

Sounds like you are getting coolant inside the cumbustion chambers in the engine. possible blown head gasket, or cracked head. get it checked by a pro. this could be very costly, but messing with it could cause more damage, such as bent connecting rods from trying to compress liquid coolant. good luck.

What is causing white smoke coming out of the mufflers when I start the engine?

It's normal for a thin white smoke to come out of the exhaust at initial start up. This is caused from moisture built up in the exhaust burning off. However if there is a continuous flow of thick white smoke it could be a blown head gasket causing coolant to burn.

White smoke coming from the muffler, loud noise...

One potential cause is too much gas. It may be running "rich". Your car may also be burning a little oil. White smoke is water or antifreeze. If you are loosing coolant from the radiator, it's probably a blown head gasket. If not, it is just condensation in the exhaust pipe that is evaporating as the pipes heat up. If the car is running too rich, the unburned gas will cause black smoke and burning oil smoke will be blue.

Hope helps (remember rated this).

2007 Nissan Altima - smoke from tailpipe

It sounds normal white smoke comes from moisture in the air as it's burned and the air temprature is different. it creates steam they gray smoke is a little harder to decide what it is, normally gray smoke is related to oil burning and black is over fuel, depending on how many miles it has on it it could have bad valve guide seals but would not worry about it.
