How to Quickly Cool Down an Engine?

[VonCarlos]

Here are the specific methods for quickly cooling down an engine: 1. Idle operation: Slow down and pull over to the side of the road. Do not rush to turn off the engine immediately, as excessively high water temperature can cause the piston, cylinder walls, cylinder, and crankshaft to overheat, thinning the engine oil and reducing its lubricating effect. If the engine is turned off at this point, the components will still be in an expanded state, with very small gaps between parts. This can lead to the detachment of some soft metals or even cause cylinder sticking. Therefore, when overheating is detected, do not shut off the engine immediately. Instead, keep it idling temporarily and try to cool it down. 2. Physical cooling: Never pour cold water directly onto the engine to cool it down, as this may cause the engine block to crack due to sudden cooling. The correct method is to wear gloves and place a folded wet cloth over the radiator cap. Gently unscrew the radiator cap slightly to allow steam to escape slowly. Once the radiator pressure has dropped, add cool water or antifreeze.
