I just bought a 67 Eldorado & the heater hoses were disconnected. I have one hose from the heater core to a diaphragm & then to the top of the engine next to the distributor. The 2nd hose goes from the heater core to ??? Does anyone have a diagram of the 429 engine or know where it connects to?? I would assume it connects to the water pump but cannot find the spot. Hopefully the heater core is OK. The previous owner stated the heat was not very good but worked slightly. I hope he was just not mechanically inclined & didn't know. I don't know much about the Eldorado so this will probably be my first post of many. Any help will be appreciated.
