'91 Dakota 3.9l

i was driving around with a friend and as i was parking the truck in the driveway coolant started pouring out the bottom of the truck. i opened the hood and the top of the waterpump pulley is wet and everything below the radiator is wet...possibly water pump or...?

 

Dump some straight water in and start it up may just be a blown house.

 

Check the bypass hose, the small one that runs from the intake to the water pump, kinda sits under the air compressor, a bad spot to get to. Good luck with it.
