how many blades and what's the diameter of an original fan ? And is there a part # for something like this ?

 

I think you need to give more info. I will assume 455. A/C?
Probably 7 blades

455 no AC

 

Is your car running hot

 

I got a lot of extra parts with a 442 I bought, including a fan. Am wondering if the fan is correct for the 442 or just a random piece unrelated to the car.

The recent prior owners passed everything along (now to me) and the first owner of the parts and car is in the big Olds show in the sky.

 

Look on the fan hub where it bolts to the water pump, and there will be a part# and date code.

 

On mine, 7 blades - 18.5 inches dia. (no A/C) The only number I can see on the blades is 416623. There is no clutch so I can't spin it freely.
