Because one heater hose is 5/8" and the other is 3/4" there is a special connector just for this job.
Its black plastic and has both of the above sizes to make a temporary loop.
Simply remove the heater hoses from the core after draining some coolant.
Attach hoses to adaptor, clamp it, good to go until repair is made.
