停车熄火后，所有指示灯都熄灭，车匙亦已拔出，却仍能听到发动机发动的嗡嗡声，插入钥匙在打火，重新关闭电源， 这次发动机停止工作。 但当时未注意水箱指示。间隔2个小时后，再次开车，还为打火就发现水箱指针居然指在表盘中央，请问高手这是什末原因。需不需要开去车行检查。
谢谢！

are you sure it is the engine runs not the cool fan runs after the key is off,
and this is the key question.

My friend said it was cool fans run since she noticed the sound first. I am blind of the car, yes, maybe it was fans runing. but how come the water box temperature was keeping so high in 2 hours? if it was key problem, is it a big problem?  If i send this car to garage, do you think they can find this problem by normal checking?
