At what temperature does engine damage occur?

As temperature of an engine exceeds 230 degrees Fahrenheit, the engine is overheated. Above 245 degrees Fahrenheit, damage may occur. As heat continues to increase, the different rates of thermal expansion cause metal to distort.

Can an overheated engine be fixed?

Your radiator is likely already damaged, but in the early stages of overheating, it can be repaired. The more you drive on it, the more you’re likely to see burst hoses burst, failed radiator stems, and exploding cooling systems.

Severe Engine Damage from Engine Overheating: Cracked Engine Block. Just like the cylinder head can warp from excess heat, so can the engine block. As superheated areas of the engine block expand and contract, it can form cracks leading to significant oil leaks, loss of performance and further overheating.
