94 grand am gt 3100 ; heater core inlet and outlet
I had to cut hoses off cause the plastic core lines cracked and by-passed core with other hose. So, I have new core in place but I dont know which lines to get.
1.outlet:
2.inlet cut to fit:
3.heater to pipe cut to fit:
all show same specs 1" I.D. or smaller
should I go with 1&2 or 1&3?
I have bad memory and dont remember which 2 it is. and auto stores are no help.
