to do ANY back flush you will need to go to the autoparts store and get a backflush kit, they are inexpensive, but it is well worth it, now if you look at your firewall (the wall between your engine compartment and the interior) there will be two hoses coming out in close proximity to each other. usually near the center or like on my 2001 grand am closer to the drivers side. those are your heater inlet and outlet, the one you are looking for is the heater inlet, it runs from the firewall to the top of the engine, the outlet runs to the water pump you will then need to follow the directions on the specific backflush kit you purchased, but it will always be on the heater INLET hose. hope this helped
