I'm getting ready to install a rebuilt heater in my 56 pickup. It's the original style round core. I can't find any diagrams in the manual on the heater and was wondering if someone can tell me which hoses go where. The core has an upper and a lower pipe when viewed from the engine compartment. Thermostat to upper? Thermostat to lower? Thanks for any help.
