What are the precautions for assessing water-damaged vehicles?

[LeSkylar]

Precautions for vehicle damage assessment are as follows: 1. Key considerations: Remind customers that starting the vehicle before repairs is strictly prohibited; test driving is only permitted after inspection and confirmation post-repair; prevent engine damage caused by water ingress in the intake system; create and display "Do Not Start" warning signs—print them, place in plastic sleeves, and affix to the front/rear windshields and left/right rear door windows of the affected vehicle. 2. Special component notes: ABS pumps and sensors are generally not damaged by water exposure and do not require replacement; spark plugs only need cleaning; catalytic converters with water ingress typically don’t need replacement—normally starting the engine post-repair will expel internal moisture via exhaust heat.
