Why Is White Smoke Ejecting From My Car's Exhaust Pipe?

We realize that seeing white smoke coming from your vehicle's exhaust pipe can be a cause for concern. It is not a normal circumstance - so what does it signify? First of all, your vehicle's exhaust pipe is where your car's fumes are discharged. White smoke is not normal; however, it does not necessarily always point to a critical issue. Here are some of the common causes of white exhaust smoke that we've seen in our shop: 


If you notice the white smoke on a brisk, cold day and you only just started your vehicle, you may just be seeing steam from condensation. Wait it out and see if the smoke will clear quickly. 

Coolant Leak 

A coolant leak is a common cause of white exhaust smoke. If there is a coolant leak in your vehicle, you may also smell a sweet syrupy scent. Beware because low coolant can cause damage to your vehicle's engine and surrounding components. Take your car to an auto repair shop, so getting this taken care of quickly. 

Cracked Cylinder Head 

A broken cylinder head, a failing head gasket, or a cracked engine block can also bring about white-colored emissions. In this instance, coolant is slipping into the cylinders or combustion chamber, which causes the white vapor. You should resolve any issue with your vehicle's engine as quickly as possible to minimize further damage.

Bad Fuel Injector 

In diesel transports, a fuel injector that is failing or not pumping at the right moment can cause issues with fuel getting to the engine, which can lead to thick white smoke coming out of the exhaust. 

While the issues listed above are just regular occurrences, the best way to truly know the problem is by coming into DRIVE AutoCare for a proper assessment.
