i blew my lower rad hose and engine ran for 1 min --u guys think that i ruined my engine or what :shakehead:

You'll have to replace the hose, fill it up and see what happens.

I agree with isamu. You should be ok. I once had an RX-7 overheat while I left it running outside, and most of the coolant was on the floor. After I filled it up and cooled it down it ran fine.
