It's fixed -or at least I think it is. I replaced the broken plastic pice with a brass, barbed 3/8" connector and used some new hose clamps. Was able to fill coolant, then let car run and it rwzched 180 degrees,took for a short spin and back home.
Will let it cool off and top off coolant tomorrow - left bleeder valve up to get air out, then will run it again.
Thanks everyone - assistance was much appreciated
