how to replace the cooling system distribution pipe, where to start first

drain back the coolant from the system

I said the wires mixed so I need the car wiring diagrams

two bolts hold it on, you can reach those by 1-covering your drivers side(usa cars-left hand drive) fender with a towel so not to scratch your fender with belt bucket, etc 2- reach down and disconnect all hoses, two of my three branches off the pipe were broken off so it might be diffucult to get those hoses off without taking possilby the intake manifold off. I am an amatuer so I am not sure. I got mine off because two branches were broke off, the far brannch which I thinks is the bypass hose connection to the water pump?? and the middle branch which goes to one of the heater hose inlets. I have two nubiras so I can look at the other one if I get confused. You can disconnect the old pipe pretty easy but the challenge will be getting the old hoses off and back on the new coolant pipe. If you have any ideas facebook me at Joe Cancemi Jr or email me at jcjr7@yahoo.com I could use a source for a new about a 3/8 hose or 1/2 inch hose that goes from the lower part of the coolant resevoir to the first branch on the coolant pipe I believe?
