White smoke from your exhaust? Here's what it could mean 💨
Ever notice white smoke coming from your exhaust? A little thin white v***r when you first start your car, especially on a cold morning, is usually normal condensation. It should disappear as your engine warms up. But thick white smoke that continues after your car reaches operating temperature could be a sign of something more serious.
Persistent white exhaust smoke can sometimes mean coolant is entering the combustion chamber due to a head gasket issue or another internal engine problem. If you also notice coolant loss, overheating, or a sweet smell from the exhaust, have your vehicle inspected promptly. Catching the problem early could help prevent major engine damage.
