Why is your car making smoke without being overheated

Have you ever noticed smoke coming from the engine car while driving or after starting the engine? Well, sometimes it is pretty standard for such an occurrence. Usually, during cold weather, regardless of the car you drive (diesel or gas), white smoke from the exhaust is normal for running a car.

However, if the duration for which the smoke keeps on coming gets lengthier, you will likely start getting worried. The first thought you might encounter is whether your car is overheated. But sometimes, overheating may not be the issue at all. The root cause, after all, may be something else. If you see white smoke without overheating, make a trip to the auto repair in Houston (if you are in that city). So on encountering such a problem, it is better to search for car repair near me in Houston. 

What causes the smoke, if not overheating?

White smoke emits from the exhaust.

The car exhaust is usually the primary place where smoke is likely to come from. One of the typical reasons for such an occurrence is condensation. There is nothing serious to worry about if this is the diagnosis of your car. Usually, when you start the car engine during cold weather, some white smoke is bound to come out. This happens because the hot exhaust gas of the car comes in contact with the cold air, which results in condensation and steam formation. Typically, the white smoke is likely to get cleared out in about 30 seconds, and there is nothing to worry about!

Issues with the engine control module or oil leakage can cause white smoke to come from the car engine.

ECM problem

 Many times, the issue could be as simple as a computer fault resulting in white smoke. Specifically, the Engine Control Module (ECM) can become erroneous and send the wrong signals to some car parts. For instance, faulty ECM might send false alerts to the fuel injectors, resulting in irregular fuel delivery. Hence, white smoke is emitted when the engine fails to receive the optimum amount of fuel. 

Oil leaking

Suppose you see white smoke emitting from the car’s hood, precisely the engine, then you must do a little inspection. See if there is a burning smell from the vehicle but not overheating; given this scenario, oil is probably burning. There is likely an oil leak somewhere inside. Also, too much oil leaking can cause oil to drip onto the exhaust or even the catalytic converter and then cause burning.

White smoke emits from the electrical system.

Smoke emission from the electrical system is not a very common occurrence. This is because most of the cards are laid with wires and are insulated. Nevertheless, it can happen sometimes. Maybe because of hotwiring or an alternator. 

When smoke emits from a hotwire, there is a very intense burning smell. The smell is enough to indicate what the problem is without fail. 

 Therefore, now you know your car’s most distinct four areas from where white smoke may be emitting. Some issues with these areas may be the root cause of unusual white smoke when there is no overheating of the engine itself. Addressing this issue might be a bit of an expense on your part. Therefore, it is essential to keep in mind to regularly check and inspect your car from an auto repair shop.
