im needing help with the routing of all the hoses running to the heater core and radiator.i bought the car and the heater core had been bypassed because it was leaking and i replaced it and the radiator but dont know where to hook every thing back up to where its supposed to be.it has the 305 fi.the radiator has the heater return hose.i need help on it or some where where i can get the routing.

 

It depends on if your car is tuned port or throttle body injected. Im not sure about the tbi. If its TPI you can run from the water pump to the heater core and then back to the radiator. If you retain the diverter valve for the heavy duty oil cooler, personally I would get rid of it, oil and antifreeze do not mix at all, if that sandwitch cooler blows a leak your engine is junk. I installed a remote oil filter up front to help cool the oil. Aside from that I dont know what engine you have and if your planning on keeping the diverter valve, or if you even have one. Any how the heater core takes two different size hoses I think 3/4" from the water pump to the heater core, and 5/8" from the heater core to the radiator. If u have tpi u may also need to go through the passover under the throttle body, I deleted mine and welded the holes shut, cold air vs. hot water dosen't make much sense. However I hope I've been of some assistance to ya!
