I am about to change out all my hoses and wanted some advice before I charge right in there. In reguards to the heater core..... I cant see where the heater hose connects to, can I do it from the engine compartment or do I need to get to them from inside the car to replace the hoses? I am going to replace the hot water shut off valve as well. There is a piece of metal pipe about 6 inches long in the middle of the hose from the water pump to the heater core, I think its to keep it from touching the headders and melting, should that be attached to something? its just kind of floating aroudn now, with nothing to attach it to anywhere. Any other ideas or comments before I start?
