When too much water is introduced into your motor's cylinders it results in hydrostatic lock, or “hydrolock,” an engine state in which the pistons freeze and the engine stalls. Water does not compress like air which is what causes the sudden stop.

Can you leave an engine in the rain?

Modern engines are water-resistant, meaning they are built to make it difficult for water to get in.

This situation is also known as hydrolock and can cause the engine to stall. If the water in the combustion chamber is in small amounts, it is often eliminated by engine heat.

Is it bad to let rain dry on your car?

How do you dry out a wet car engine?

Once the engine is out of the water, you'll need to get the water out of the engine. Disconnect the battery—ground cable, then positive cable—and set it somewhere dry. Remove plastic engine covers and dry everything you can reach with shop towels. Pull the spark plugs and hand-crank the engine over a few times.

Can you fix a water damaged engine?
