One day pulling into Burger Supreme, the engine steamed, sounded like a geyser going off, steam everywhere.

Fearing a blown coolant hose, I pulled over, shut her down and popped the hood. Nice and clean, not one drop of coolant out of the overflow (no smell either). Never did it again. Not sure where that much water could be trapped to suddenly vaporize on the header like that, but it did.

It's a dodge thing.

Could be lots of stuff, from a dying battery to a bad ground.
