Sorry about my counting ability. I am using the 5 blade 1950-52 Buick Roadmaster fan (non-A/C cars), which is pictured above.

The fan blade is very close to the rad, I would bet 5/8 inch or so. It almost touched the bottom of the upper tank of the rad. I used a 59 cad a/c 6 blade fan. I really like it and unless there is a buick expert looking under the hood and looking very close, no one will really knows that it is not stock.

Thanks Rusty, I must have the exact same fan as you--mine has 7 blades though...yours is 6? Grandpa, I looked for one of those Roadie fans but couldn't find one, so I went with the Caddy!

The 6 blade 59 Cadillac fan blade on my 53 Special 45R is under an a inch away from the radiator. The shape of the blades is very similar to the original 4 blade fan and is difficult to see that it is 6 blades. By the way, the seven blade Cadillac fan was used for limousines and possibly the Cadillac Series 75 commercial chassis ( for hearses and flower cars).

Hmmmmm. Looks like I have a limo fan. Seems to work well. I feel bad for my water pump bearing...that thing's probably twice the weight of the old one! Thanks for the reply, Joe.
