Soldato
The water will have gone into small nooks and crannies then frozen. Water expands as it freezes (ever left a bottle of coke in the freezer?) and there is a real risk of the car being wrecked as this happens.why would it? if you melt the ice to open the door so you don't break the door lock/handle, and start the engine it should be fine?
you get anti freeze in engine coolant/clutch fluid?
