In Reply to: Auxillary fan... posted by gerry on December 21, 1999 at 22:42:10:
I installed one from a late 320. I only had to make two small brackets and it bolts where the rad bolts in the radiator support core. It is triggered with two switches in paralel. One is a mechanical switch in the cockpit, the other one is a thermoswitch.
The fan can start by itself if it gets to hot, or I can switch it on myself.
