My Model B has this V8 water pump. No holes in the pulley so no fan. What are my options for installing a fan?
That early V8 pump is a fairly common setup for a banger, try the monthly 4 banger thread; https://www.jalopyjournal.com/forum...read-april-showers-bring-may-bangers.1333324/
From the patina it looks like you have gotten along for a long time without a fan. Why do you want one now, that information might suggest a solution? Having said that you do realize you have a Model A cylinder head (4 bolt water pump with water outlet on top)? The solution might be to go to a Model A water pump. From a functional point can you install a "pusher" electric fan in front of the radiator? (Looks like hell if it is visible but I don't know what the rest of the vehicle looks like) Charlie Stephens
I believe Charlie Yapp over at Secrets magazine had an article showing how to do one. Give him a call maybe he still has the back issue.
