electric fans
For a bunch of reasons I want to put an electric fan in my 34. Please don't judge me! My issue is room, I bought one from Cooling components but its too thick. What that means is the motor on fan sticks out far enough to hit my pully on alternator. This is a 59ab with a 12v conversion. the alternator sits at center like the original generator did. Has anyone on the barn made this change and if so what fan did you use? I have only 2 3/4 inches from radiator core to pulley. Thanks for any help. Ken

Re: electric fans
I have a '38 which has the tall, narrow radiator like your '34. The shroud doesn't cover the entire core, so I placed it at the bottom for clearance. Mine is on an 8BA engine. I used the 16 series fan that requires 4" of clearance and put the motor in the area below the alternator. I really like the Cooling Component fan. It is quiet and it cools the engine in Mississippi summer heat.

Ken....Not fully understanding the specifics to your build, did you realize that there is an alternator pully available that is drilled for a fan, just like used on the original '32-'38 Fords (plus '39 Standard)? The one I speak of is available at Speedway Motors.....link BELOW! DD https://www.speedwaymotors.com/Offen...ord,25025.html |

Re: electric fans
Do you have room in front of the radiator to mount? I mounted my 48 in front of the rad to add additional flow to help the stock fan. Texas summer heat.

Re: electric fans
So, you've got my curiosity up.....WHY do you need an electric fan? I realize that you indicated that you have multiple reasons. Wanna share? DD

Re: electric fans
DD, so I won a walker radiator at a nsra show, the radiator had no fan tunnel in the top tank for the fan to clear. I had a local shop make a tunnel. unfortunately it is a bit too narrow, the fan misses but its too close for comfort. on a 34 if you want your hood to fit well against the grill there is no front to rear adjustment to correct this. Also I have heard that these chevy alternators we tend to use with 12v conversions do not have a heavy enough bearing to swing Henrys steel fan for long without issues. I ran the car for its first summer with some shims under the front motor mounts that helped the clearance issue but now I'm hearing some faint noise at alt. With the shims in place my engine crank wont line up with crank pulley, not that I plan to crank start it but its nice to turn engine for valve adjusting ect. Ken

Re: electric fans
Im going to call Cooling Components today, looks like they have a narrow version that would work, fingers crossed they take this one back. Ken

Re: electric fans
So, just an update..I bought a Cooling Component 1750, its much more shallow and fits the 34 without issues. yay! tolerances are close at alternator pulley but it fits. They were nice enough to accept the 1650 back on return so 1750 is the way to go if you want an electric fan with a stock 34 running a 59ab. Ken
