My car was giving off white smoke after it overheated. What’s wrong?
When you experience car overheating and smoking together, it usually means your engine has a blown head gasket. This gasket seals the head to the block. If the engine overheats, the block and head can warp, damaging this seal. Once the seal fails, coolant can leak into the cylinders. This liquid is turned into steam, and passes out through your exhaust. Unfortunately, this is an expensive repair, Removing the head is a complicated process, and both the head and engine block may need to be machined to flatten their surfaces.
