Took the Packard out early this week with 95 degree heat and the AC on full blast. Ran fine, didn't overheat but ran warmer than I would like, about 200 (new gauge has numbers). Decided to go with Plan B, adding the mechanical fan back on the water pump. The problem was that with the single belt arrangement with the compressor on the left, the fan in the original position hit the clutch of the compressor. I had planned to build a spacer, if necessary, to move the fan toward the radiator about 7/16". On most cars this would be pretty simple, drill 4 holes in a spacer and bolt it on. Not so with Packard, it has a lip on water pump bracket that centers the fan. This makes a spacer much more difficult to build.

I started by buying a $6 piece of 5/8" thick aluminum billet. First used a hole saw with the correct inside diameter to cut the relief that will center the fan on the front of the adapter. Then used another hole saw to cut into the back of the spacer for the hole to center the back of the spacer on the water pump. Then used a 2 3/4" hole saw to get the round 2 1/2" round disk. Used a drill press for this.I have a small lathe but it is not powerful enough the carve out the excess material to finish the spacer. I used a 1/2" end mill in a drill press with a clamp to carve out the excess material. Not as pretty as using a lathe but equally effective. Drilled the 4 mounting holes and it is ready to mount. Would have been much easier with a lathe, but still possible with some available tools!

Now the hardest part, getting the assembly mounted with little room!
