Al:

Here is a picture of my heater hose routing. The upper heater outlet goes to the top of the water pump; the lower heater outlet goes to the engine's head.

As an aside, I fabricated a metal pipe that runs the length of the engine for the upper heater outlet hose rather than have a rubber hose draped over the engine. I did this mainly for looks. I used 3/4" copper tubing and had to make the brackets.

Hope this helps.

By the way, my car is a 1937 120.

It is hard to visualize with only the side perspective so maybe there is a reason but did Packard cross the hoses? In that view I would have reversed the heater connections to make the hoses lay a bit differently.

Function over Form.

There is no increased function with the crossed heater hoses. An uncrossed hose layout would look better and there would be no loss of heating efficiency. Also, there is no valve on the cylinder head so there is a constant flow of coolant through the heater core. I do like the idea of a pipe from the water pump over the engine to the heater hose to avoid a drooping hose on the head. After all, it's all about looking good.
