@allinknows: Thermal shock is a process that can cause severe damage when cold water is poured onto a scorching hot engine. An engine's metal parts expand as they absorb heat as it overheats. When cold water is suddenly added, the inside parts stay hot and expand while the exterior surfaces quickly cool and contract. Intense internal stress caused by this unequal contraction may result in broken radiators, distorted cylinder heads, or cracked engine blocks. A seemingly simple solution might quickly transform an overheating problem into an expensive mechanical breakdown. The safest strategy to avoid irreversible damage is to let the engine cool naturally and deal with the underlying cause of the overheating. #everyone @allinknows
