restoring a 58 eldorado broughman and had engine just sitting in car when I got it, was curious to what was the heater hose routing was the water pump has a outlet on rear middle, left front of cylinder head has outlet, and the are two outlets on front of water pump, engine was rebuilt prior to getting car and i believe water pump goes to a 1958( i think those are 1 year only). I have searched the manual and internet and having no luck. the hoses that go to the rear heater are still connected to the heater core and have not been touched, any help would be greatly appreciated.    thank you, TL

Tim, at least have a look at page 14-1 from the Brougham supplement, you will get the diagram. I restored a '57 Brougham, but the pictures I have a difficult to see. Anyway, I believe that the '58 Brougham used the same cooling for the transmission than the '57 one. This is the outlet at the rear of the water pump. You must have another water outlet above the starter motor. I'm attaching the pictures which may help.
Good luck!
Sorry, the server will not my small analog pictures. If you are sending me your email, I can send them that way.

       You are almost right about the water pump. The 1958 Brougham uses pump #3630893. It is the only exception  to the "one year only" 1957 air conditioned pump.  The main difference, is side the large intake nipple is on.
       In the March 1958 Serviceman,there is a picture and explanation of how the heater hoses should be routed to the main heater. It seems some 1957 & 58 's came routed wrong from the factory,so the heater only worked on high.
   With what Roger says for the transmission connection,you should be good shape.
 Good luck Warren

Thanks Warren for the clarification. As the frame was the same for 1957 & 58, the water pump had to be the same! I'm attaching the scan from that bulletin; it seems that you did more searches than me!
