What damage can be done if a car overheats?
Severe Engine Damage from Engine Overheating: Cracked Engine Block. Just like the cylinder head can warp from excess heat, so can the engine block.

Overheating occurs in winter due to a deficiency that occurs in a vehicle’s cooling system. Most common faults are coolant leaks or a blocked thermostat.
