What is the correct heater hose routing and length for the heater hose that goes from the water pump housing to the heater core? I've seen pictures of the hose going from the housing into the retaining bracket on the front of the head and then to the heater core. The other pictures I've seen go from the housing through a retaining bracket on the inner fender then to the heater core with no retaining bracket on the front of the head. Is the bracket on the front of the head always used? Could it possibly use the bracket on the front of the head and the retaining bracket on the inner fender together? Service manual shows either or.
