5 Causes of a Smoking Car and What You Should Do

Did you know that the average age of cars on American roads has increased to over a dozen years?

The older a vehicle gets, the more prone to issues. Not only is it alarming to see smoke rising from your car, but it’s often a sign of serious vehicle problems.

Are you wondering what to look out for? Keep reading to learn five common causes of a smoking car and what you should do.

1. An Overheating Engine

One of the most usual causes of a smoking hood is an overheating engine. When the engine temperature rises beyond the normal range, it can cause the oil and other fluids in the engine to burn. That’s where the smoke comes from.

Take a look at the temperature gauge on your dashboard. If it’s reading higher than normal, pull over to a safe place right away and turn off the engine. Let the engine cool down before checking the coolant levels.

If the coolant levels are low, refill them and check for any leaks. Is the problem persisting? In this case, you might need the help of a professional mechanic.

2. Broken or Leaking Gaskets

Another cause of a smoking vehicle is a broken or leaking gasket. The gasket is a small part that sits between two larger components of the engine, such as the cylinder head and engine block.

If the gasket gets damaged, it can allow oil or coolant to leak into the combustion chamber, causing smoke to come from the exhaust. If you suspect that your car’s gasket is broken, it’s essential to take your vehicle to a mechanic as soon as possible.

3. Faulty Transmission

A faulty transmission can also result in a smoking, broke down vehicle. When the transmission fluid gets too hot, it can cause the transmission to overheat and a good deal of smoke.

If you notice smoke coming out from under your car’s hood, check the transmission fluid levels. As with the coolant levels, refill them if they’re low.

4. Clogged Catalytic Converter

Are you wondering what else can make your car smoke? A clogged catalytic converter is another possible culprit. The job of this car part involves converting harmful exhaust gases into less harmful ones.

When the converter gets clogged, the exhaust will back up and create smoke. If you suspect that your car’s catalytic converter is clogged, take it to a mechanic.

5. Failed Piston Rings Failed

Piston rings are yet another possible cause of a smoking hood. The piston rings are responsible for keeping the oil in the engine from entering the combustion chamber.

When the rings fail, oil can leak into the combustion chamber. After that, you could have lots of smoke and a broke down car.
