The most common reason for car blowing white smoke but not overheating is that there is some kind of liquid that resides in the engine. This could be motor oil, gasoline, liquid transfer, coolant, or condenser. It can make your engine smoke because it burns that liquid in the engine. However, this will not cause your engine to overheat, which will lead to significant problems that will cause you to pull over and lock your car.

Reasons Why Your Car Blowing White Smoke But Not Overheating?
Below are some of the top reasons:
1. Head Gasket Failed
The failed head gasket is caused by a cooling system that no longer performs its function. For example, when the car engine is too hot, the heat will cause the engine block and cylinder head to rise larger than they should, failing the head gasket.
This allows the antifreeze to leak into the combustion chamber, causing white smoke to escape when the gas is released. If you see smoke, your car may not immediately show signs of overheating, but that is exactly what is happening. You might think that your car’s temperature may indicate a problem, but you can’t even handle that.
Extreme heat may be due to a variety of factors, including:
- Leaking pipe cooling
- Loose or disconnected pipe
- Radiator broke or failed
- When this arises, no quantity of water in the cooling system is possible to adequately contain the heat.
If you have a broken gasket, the only way to fix it is to open the engine and replace it. Remove all leaks from the cylinder before adjusting the head gasket. If you are not mechanically inclined, you will need to take the car to a mechanic for repairs.
2. Condensation
It might be just condensation if you start your car after a few hours of rest on a chilly day and observe some little amount of white smoke coming out of the exhaust.
If the car blowing white smoke but not overheating lasts only for a few seconds or minutes, water is much more usually present in the exhaust. The water has dried out as the smoke has stopped. If this is the case, there’s nothing to be concerned about.
3. Water In Exhaust System
The exhaust system can be in danger when water leaks from improper or dirty turbos to their cooling channels. This error will cause the engine to malfunction even though you may not notice a change in your car’s smooth operation until you later get off the line.
If you have a faulty turbo due to water leaks, you will see white smoke probably coming from the engine area, so stay alert for signs of a problem with something so important.
If this is a problem, you will need to change the turbo to stop the water leak.
4. Cooling Tank Damage
While this is normal, a damaged coolant tank may cause you to see white smoke coming from your chimney. Cracking of the lake often causes this problem.
The best way to diagnose this problem is to check your coolant reservoir tank. Look for signs of dent or cracks, and don’t forget to open the cap to see if there are any visible leaks inside it.
If you find that your pool has cracks in it, you will need to replace it immediately as the cooler will leak into your ventilation system until you have properly repaired it.
5. Oil Leaks
You can also detect potential oil leaks if you see white smoke rising from your exhaust system.
The white smoke emanating from the ice may have covered the various parts of the engine’s combustion chamber. If so, it means that your piston rings have failed and need to be replaced to stop oil leaks.
If not, there may be a problem with the valve valves or perhaps a cracked head gasket that allows air and fuel to mix, which can lead to serious damage over time. The moment you experience oil leaks, the smoke you will see coming out of the swamp will have a blue tint, but most people often make the same mistake as white.
How To Get Rid Of White Smoke From Car Exhaust?
You can fix the problem of white smoke in any car engine – diesel or gas. However, some of the problem-solving methods are not at all compatible with DIY (such as repairing and replacing the head gasket) and you should seek professional help with them.
Step 1: Check Any Crack In Intake Manifold Gasket
The first thing you should check, you might think, is a head gasket, but before that, you should first check a lot of gaskets. The suction gasket covers most of the feed; it not only transports the coolant to the engine but also carries oxygen. If a suction gasket becomes cracked, the engine overheats due to leakage of coolant, air, and gas. Remember that the gasket is mostly made of rubber or plastic. It is therefore prone to damage due to extreme heat. Fortunately, although it can crack or be damaged, it can easily be repaired if detected early.
Step 2: Check Any Cracks In The Head Gasket
After testing the bulk gasket, you should proceed to the head gasket. The head gasket is designed to lock the heat in the block to prevent the cooler object from reaching the cylinder. If there is a crack in the head gasket, it needs to be replaced immediately.
Step 3: Check Any Cracks In Cylinder Head
The cylinder head is important as it connects to the engine block and the gasket head. Because it is made of aluminum, it tends to bend or break when the engine is overheating, releasing white smoke from the swamp. If on inspection, you see a crack, replace the cylinder head immediately.
Step 4: See Any Crack In The Engine Block
There are three ways to repair a broken engine, apply a cold-metal patch over a crack, sew it with cold metal and close it, or re-ignite a crack. These require professional work. Whichever way you choose, it’s not cheap. Engine block repair work can take from 12 to 35 hours, depending on how it is built with your car model, as in some models it becomes very difficult to get to the point where the engine breaks down. This could cost you between $ 2,500- $ 4,000 for temporary repairs.
Step 5: Delete Or Replace Oil Injector
It is also possible that your fuel injection is blocked and cannot perform its function properly. They are often at risk of being blocked by carbon deposits and mud formation. The good news is that there are commercial oil injector cleaners that can help clean the dirty stove.
Step 6: Check The Valves Or Piston Rings
Piston rings and valve seals tend to wear out and tear. If these fail, the switch is OK. Unfortunately, as simple as parts may sound, installing piston rings is very expensive, usually, from $ 1,800 to $ 3,500, parts of it work for about $ 75- $ 200 and the rest is laborious, as this is a very time-consuming task.
Conclusion
I hope that this post has answered your question about why my car blowing white smoke but not overheating.
It’s entirely up to you whether you want to handle this problem on your own or seek professional assistance from any auto shop. You can try this focus depending on your degree of skill. Whatever you do, unless the problem is caused by condensation, don’t ignore it.
