What to Do When a Car Engine Gets Submerged in Water?

[ColeDella]

Do not start the engine after it has been submerged in water. Below are detailed explanations of the causes of engine water ingress and solutions: 1. The engine has not been started. Solution: If the engine was not started during the submersion, it generally will not cause irreversible damage to the engine. The main task is to remove the accumulated water inside the engine. This involves removing the intake pipe and intake manifold and using compressed air to dry out the interior. 2. The engine stalls due to water ingress. Solution: By using a caliper to measure, you can compare the distance from two pistons in the same cylinder to the upper edge of the cylinder. If there is a difference in the measurements, the side with the larger value may indicate a deformed connecting rod. This can be further confirmed by rotating the crankshaft to position both pistons at top dead center and checking if the edges of the pistons are flush with the upper edge of the cylinder.
