31-57 radiator fan exploded. Need new one.

Recommended Posts

  Hello ladies and gentlemen,  Some of you may remember me from the Oklahoma buick meet last year in Oklahoma. I had a 31-57 at the show and my 3 year old daughter enjoyed the show as much as my wife and I. Well we have not drove the car much at all this year due to covid  shutting down car shows and other things.  Yesterday my daughter begged me to take her out in the old buick and the weather was probably as cool as we were going to get for July so we charged the battery, fired her up and pulled out down the road. My daughter grinning from ear to ear. About 8 miles down the road the car got a vibration. At first I was thinking a tire going down and then we heard a loud bang like metal against metal. I eased of the throttle and coasted into a gas station. Antifreeze pouring out from under the car. I raise the hood and find a fan blade missing. It broke off and sliced up the radiator. Upon further inspection I find that 2 other blades are cracked and about to break as well. Looking at the metal break it appears there have been hair line cracks in the blades for some time as a portion of the cracks are rusty instead of being clean shiny metal throughout the entire break. Has anyone ever had anything like this happen before? Know what causes this failure? And most importantly does anyone out there have a fan assembley that would be correct for a 31-57? I have very limited internet access so if anyone has any ideas, or has a fan assembly please call me . Shawn 918-607-3923 or email me at seldredge76@hotmail.com. Thanks guys.

Did it dent the hood too ?   I had a Ford with a dent in the hood right in line with the fan, which served as a reminder to inspect the fan blades frequently.

It could have been worse. This Dodge suffered  major damage from a fan breaking.  Fan, water pump, hood, fender all damaged.

Metal fatigue.  A good reminder for everyone to check their fan blades regularly

 

I hope your repairs are easily done..

Sorry to hear about your breakdown. At least you weren't on the Peking to Paris route. Looking at your photos the bolt circle where the fan  attaches to the hub looks almost the same as my 1929 Buick. 1929 parts seem to be much more plentiful than 1931 parts. Someone may have a spare .

Shawn:

So sorry for the fan failure. I know how enthusiastic you were about having your car to the nationals. I was the judging team captain. We spoke at some length about your car.

Now we need to get you a new fan!

Not sure if a '32 will interchange, but Pete Phillips might have one if they do interchange.

Some may be surprised to learn that years ago,  I gave half of my spare fan to Jack Gerstkemper when he needed a replacement for his father's 1931 50 series Roadster. 

I will see if I still have the other half.  Stay tuned...
