What Causes White Smoke from Engine?

Smoke often leaves the engine of your car due to overheating. With the points below, you will be able to tell the exact cause of this fault in your car.

  • Leaking Fluids from the Car: This is one of the major causes of this fault. There are so many fluids in the car. They include; the coolant, Brake fluid, transmission fluid, power steering fluid, window washer solvent, etc. when there is a leakage in any of these fluids, you would notice the fault in your car. Most of these fluids smell sweet, especially the coolant. So, when the smoke has a sweet smell, the leakage of any of these vehicle fluids would be the cause. A thick white exhaust smoke usually indicates a leak of coolant, which can cause overheating and damage your engine. So, you should fix this as soon as you notice it.
  • A Blown Head Gasket: This is a more serious cause of this fault. The Head gasket is the seal between a vehicle’s cylinder head and the engine block. When there is a crack in this automobile part, the coolant may begin to leak causing thick fumes of white smoke from the car. Also, under extremely low-temperature conditions, the coolant freezes and this causes cracks in the wall of the parts resulting in this fault.
  • Burning Electrical wires: This could also cause this fault in a car, although it is rare. To confirm that burning wires are the cause, you would notice a pungent smell from the smoke.

These are the possible causes of this fault in a vehicle and you can easily detect them by lifting the hood of your car. If the leaking coolant is the fault, you should replace the hoses. You can get good hoses for your car on AmazonBUY NOW ON AMAZON
