Distinctive odor helps quickly identify damage to the car

Smell of engine oil

Engine oil leaks in two typical states: pressurized and unpressurized. When you smell oil, the engine is leaking engine oil under pressure caused by operation. Engine oil will leak through the vehicle's exhaust pipe.

In this case, you should check the oil dipstick and add the leaked oil to keep the engine running normally, then take the vehicle for timely inspection and maintenance.

Smell of gasoline

There are many reasons why a car smells of gasoline, such as a leaking gas tank cap; a punctured or cracked gas line from the tank that causes gasoline to leak out into the engine, causing the gasoline smell to rise.

A car that smells of gasoline is a warning sign of a possible gasoline leak, which can easily lead to a car fire or explosion. Therefore, drivers should not be subjective and should check the fuel tank, fuel lines, etc.

Burnt smell

When you smell a burning smell, it means that there is a device or part that has caught fire, causing this smell. There are many causes for this, such as a burnt electrical switch or a loose belt that rubs against other devices, causing a burning sound.

Or it could be the driver's mistake of forgetting to release the handbrake, causing friction for a long time, creating a burning smell. Many people when going downhill let the car drift and use the brake continuously, the brake temperature increases, leading to a burning smell and possibly losing its effectiveness.

If you detect this smell, you should immediately stop the vehicle for inspection to avoid unfortunate situations such as brake failure causing an accident.

Burning rubber smell

When the driver detects the smell of burning rubber, it is likely that the belt is loose or the hose is not tight, hindering the movement of the parts, causing the smell of burning rubber.

Or the cause is when moving in hot weather, long vehicle operation, sudden braking causes the car to skid on the road, leading to the tires being burned by the asphalt, causing the smell of burning rubber. Drivers should limit sudden braking, braking until the tires die on the road to avoid the above phenomenon.

Musty smell

If you smell a musty odor after turning on your air conditioner or heater, it is possible that mold has grown inside the unit. While not dangerous, this can be uncomfortable and can also have long-term health effects.

Rotten egg smell

When a car smells like rotten eggs, it may be because the exhaust filter is not converting H2S to SO2 completely. This affects the air in the car. If there is a rotten egg smell and the car engine is running poorly, the car user should take the car to be repaired immediately.

Sweet syrup smell

This is most likely a smell that comes from a coolant leak, which can cause a sudden engine shutdown if the entire system overheats. If you want to open the radiator at the front of the car to check it yourself, you will need to pull over and wait for the engine to cool before checking the coolant level.

Because when opening the radiator cap while the water is boiling, steam can shoot out and cause burns.
