Trying to ID what year(s) this 5 blade fan is correct for, tried to match it to search pictures with no luck. Thank for the help.

Re: What Year is This 5 Blade Fan?
Just FYI, to add a little to maybe help others, the following is a four blade fan found on both 1965 and 1966 "292" 6 cylinder engines. The 1965 was on a low mileage one ton military ambulance, the 1966 is from a C10 pickup, both appeared to very original.

That is the same fan that is on on my 65 283 with the fan shroud and air.

Re: What Year is This 5 Blade Fan?
Earlier Chevrolets use a smaller bolt pattern on the blade mount, not sure what year they changed but I know in the early 70s they used the blade you have pictured.

Re: What Year is This 5 Blade Fan?
Is there a big "U" shape stamped in each blade around the outside of the rivets ? I don't recognize that blade at all. 292s with heavy duty cooling or V8s with AIR have a 5 blade fan similar to yours but are all 5 rivet per blade fans. The only marking on the fan is a "W" . No part number. The GM Part numbers for these blades are 3770262 or 3789562. Below is a flat rivet style and an earlier round rivet style.

63 Burban,
In My search of pictures, did find 70-72 image of fan with similar rivet pattern, not sure if original to that truck, could not see blades in that picture. Thanks, Les |

Re: What Year is This 5 Blade Fan?
I think some of the trucks built for northern climates had 3-blade fans too.
