How to Stop White Smoke from the Exhaust

You may commonly see white smoke coming from the exhaust on cooler days upon starting, probably because steam is created due to engine burning off the condensation. But if this continues for long even during warmer months, then it may indicate trouble. It is important to get your vehicle checked out and get it fixed as soon as possible. There may be several reasons for a car smoking white smoke from the exhaust. In this oneHOWTO article, we are going to talk about how to stop white smoke from the exhaust, no matter what the underlying reason is.

Worsened coolant

In some cases, the white smoke may be caused due to a deteriorated coolant in the radiator, which might be allowing coolant to enter into the car’s combustion areas. When the coolant enters the combustion area, it vaporizes and spews out from the exhaust in the form of white fog. If this is the reason why your car is smoking, the best remedy is to get your gasket replaced by a professional.

Other than that, you may also try a stop leak or neutralizing flush to stop the radiator acid as an emergency solution. You can find this type of product in specialized shops. Just follow the instructions and pour the right amount in the coolant system.

Cold weather

If you see white smoke during startup only, then this is probably because oil leaks pass the valves and mixes with any moisture present in the car’s exhaust. When you park your car under extremely cold conditions, the car becomes too cool, its air shrinks and starts producing moisture, making as much as 1 cup of water in the exhaust system and its motor. So, when you ignite after a few hours, such as in the morning after cooling overnight, this moisture comes out of the exhaust as a white smoke.

It usually comes out as a white fog and stops on its own after a couple of minutes.

Acidic problem

When sulfur gets mixed with the moisture in the engine, it produces acid. All oils, diesel and gas fuels contain sulfur. Most of them have additives to control this sulfur and keep the transmission and the engine protected.

A special motor treatment is available that aims at sealing oil loss and putting off expensive repairs of the valve. More acids in the exhaust and the motor will cause you to need to replace your motor and muffler sooner than needed. Make sure you check your oil more frequently to avoid this problem in the future and top it up frequently.

Using additive products to deal with white smoke from the exhaust

There are many additive products that you can use to fix the white smoke issue. Before taking your car for a repair, experts recommend trying to solve the issue using these products. If the problem does not get solved with these products, your car may need a special servicing in which particular attention needs to be given to dirty conditions, bad or worn out parts or the car etc. A muffler is present in all cars that is used to change unburnt gas and oil into water. With this, the exhaust does not come out, and kill the vegetation and cause pollution. So, if you can see white smoke coming from your exhaust every time and for long, then the best thing you can do is to take your car to a mechanic as soon as possible.
