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.

I just said that cause my round core has no control valves to mess with so I see no difference but its good to see the manual link... Thanks
