Causes of Hybrid Cars Out White Smoke When Warming up – Before you use a car or hybrid car, it is better if the car engine needs to warm up the engine first. This is to ensure the lubricating system or cooling system in the engine in the form of oil/lubricant, cooling water or fuel can circulate normally. More than that, by heating the car engine, we can find out if the engine is in normal condition or not. One example is by looking at the symptoms in the form of white smoke that comes out of the exhaust while it is warming up.
Causes of Hybrid Cars Out White Smoke When Warming up
Yes, in some conditions, white smoke that comes out of the exhaust when warming up can be said to be normal and normal. But these conditions can also indicate a problem occurs in the engine in your hybrid car. So what causes the car to come out white smoke when warming up the engine?
Well, in the following article, I will provide related information about the phenomenon of the appearance of white smoke from the car exhaust when the engine is warming up. Check out the review of the causes of the car coming out of white smoke when warming up the following.
1. Evaporation of Cold Air from Exhaust
Cold air in the exhaust is often the cause of white smoke coming out of the car when warming up. Conditions like this are very normal and common, so you don’t have to worry too much when the car comes out of white smoke, especially when the air is cold or in the morning.
When you don’t use the car and you just park it overnight in the cold outside air, the cold air will make all parts of the car cold. You can notice this on the body that sometimes there is often dew and water droplets all over the car body.
Of course, this will also affect the temperature and temperature in the exhaust and engine exhaust pipes. So, when the engine starts to warm up, the hot air will flow through the entire exhaust / exhaust pipe. The hot air from the engine combustion will make the cold air containing the water evaporate and then be pushed out into the exhaust. Even in some conditions, there is water that also drips out of the end of the exhaust pipe.
The principle that occurs is exactly the same when we breathe in places that have cold temperatures such as in mountainous areas, namely conditions where when we breathe there will be a phenomenon of smoke coming out of our mouths and noses.
The more water and cold air there is in the exhaust pipe, the effect of white smoke produced when the engine is warmed up will usually also last longer (at least 5-10 minutes at most).
After the water content in the exhaust runs out, the white smoke will gradually dissipate and the smoke coming out of the exhaust will return to normal, that is, it will no longer emit white smoke.
2. There is an oil leak that enters the combustion chamber
The cause of the car coming out of white smoke when heated next is the occurrence of oil leakage into the engine combustion chamber. Leaking engine oil that enters the combustion chamber can cause white smoke, along with the characteristics of the condition of white smoke coming out of the exhaust due to an oil leak that also burns in the engine.

- White smoke does not disappear after the engine is turned on for more than 10 minutes, even after the engine has been buzzing for a while.
- The white smoke that comes out looks thicker and smells like burning oil.
If the two characteristics mentioned above are seen in the white smoke coming out of the exhaust, this is a sign that you should check the engine at the nearest repair shop that you trust.
The reason is, there are several things that cause oil leaks in the engine room such as worn valve seals, worn piston rings and so on. This condition will be more dangerous if it continues, as a result you will spend more money on car engine repairs.
3. Cooling Water Seepage into the Combustion Chamber – Causes of Hybrid Cars Out White Smoke
Although it is very rare, the seepage of cooling water that enters the combustion chamber can also be the cause of white smoke when heated. This seeping water will also burn, causing water vapor to continuously come out of the exhaust.
Seepage of cooling water that enters the combustion chamber of this engine can be caused by many reasons including:
- Cylinder head gasket (head gasket) leak
- Cracks in the cylinder head or in the cylinder block
- The cylinder head is slightly bent due to the previous overheating
To be sure, you need to do a car inspection at a repair shop you trust.
