Re: watercooled engine question

the water pump stops circulating water, but as long as the thermostat is open the hot water is being exchanged with cooler water somewhat. so yeah, the engine gets a little hotter for a minute or so, but then the engine cools down after that.

because engines are different, some cars heat up a bit more than others after shutting them off. turbo engines, for example, will heat up a bit more than NA engines if you shut them off. this can even damage the turbo. newer engines don't have this problem however.
