Although I feel bad for the guy with the dead motor, I don't like the fact that he's going to try and get the car wash place to pay for it. If his motor indeed hydro-locked, it's his own fault. Should've known his intake is on the side and turned off his motor during the wash.
But I still don't understand how the motor locked up. It takes quite a bit of standing water, no?
Most of the touchless washes I've seen have the sprayers moving back and forth. Not really any worse than driving in a heavy storm.
