I'm driving to work, look behind me, and coolant is smoking out my rear view mirror.

Pull over, check everything out, the radiator by the cap is soaked, the bottom of the heater core is wet, even the battery (between the headlight housing and the battery is soaked), but the lower coolant hose isn't.

I fill it back up with coolant (always a handy resource to keep), and get to work just fine (about 3 or 4 miles). When i get to work, the truck is a 1 or 2 second drip by the passenger tire. Open the hood to look, same things are wet, obviously, but can't find any new coolant or the source of the drip.

any help?

p.s. the Sierra was a SmartLease, it got turned in recently. Needed to help my family out a little and felt selfish paying for that (and it wasn't a pretty payment)
