啥叫最近？一直都很 :-) 看到许多便宜旧车，都说发动机过热，就顺手古狗一下. 提问:

If you bough a car whose overheating is due to a fan, a thermostat, plugged radiator, even a water pump, then you are lucky.

But if the overheating is due to a blown head gasket, cracked block, then god bless you.

How difficult it is to do a head gasket? Is there a way to know if it is a blown head gasket, or a cracked block, before you pull the head?
