What are the aftereffects of repairing a water-damaged engine?

[PhoebeMarie]

After repairing a water-damaged engine (flooded vehicle), the submerged wiring may rust or short-circuit, leading to unpredictable electrical failures that can occur at any time. For example, the engine might suddenly stall while driving at high speeds, or the airbags may fail to deploy in critical moments or even deploy unexpectedly. After the engine is water-damaged, check the electrical circuits: Since dirty rainwater is an excellent conductor, circuits exposed to water are highly likely to short-circuit. After the engine is water-damaged, check whether the braking system has been flooded: Because the braking system has strong absorption capacity, rainwater can easily enter the brake fluid, affecting braking performance. In severe cases, it may cause the braking system to fail.
