Thick white smoke pouring from the exhaust is usually due to a crack in the cylinder head<\/a>, engine block<\/a> or head gasket<\/a>. This is caused by constant temperature fluctuations and a consistently overheating engine due to low coolant levels.<\/p>\n

Whenever the smoke emitted from their car\u2019s exhaust pipe is anything other than thin and grey, people tend to worry that something might have broken or stopped working internally. A common occurrence is for white smoke to be emitted in a thick burst, and it\u2019s important to differentiate between thick white smoke and thin white smoke.<\/p>\n

White Smoke From Car Exhaust<\/h2>\n

Thin white smoke is usually a result of condensation build-up within the exhaust system and will burn out fairly quickly. It also tends to occur on cold mornings. It shouldn\u2019t be something to worry about, but if it occurs in conjunction with other symptoms, such as a loss of engine performance, it may indicate a more serious issue.<\/p>\n

However, thick white smoke can be a symptom of something that could require the attention of a mechanic.<\/p>\n

Excessive White Smoke From Exhaust<\/h2>\n

When the smoke emitted is thick, white and billowing, this usually points to a crack somewhere within the internal combustion engine which is allowing coolant or oil to leak out of the areas they should be contained within. The coolant is then being burned, producing the thick white smoke.<\/p>\n

It\u2019s important that you do not ignore thick white smoke coming from the exhaust \u2013 even if it\u2019s only a small crack, the damage can easily become more extensive and this can lead to the engine breaking down completely and having to be replaced.<\/p>\n

How to Stop White Smoke From Exhaust?<\/h2>\n

If you suspect that you have developed a crack in the engine block, cylinder head or head gasket, keep an eye on the amount of coolant that your engine is using. You should check coolant levels by opening the coolant reservoir \u2013 however, even if the levels are correct, the white smoke could still indicate a leak. You should therefore conduct a thorough check of the engine (either by yourself or by taking the car to a garage) to diagnose the problem. The earlier you can catch the fault, the better.<\/p>\n","protected":false},"excerpt":{"rendered":"
