Who has an Electric Fan?

rambos_ride

Drove the 51 down to have dinner with my brother last night..by the time I got there I was overheated and steam pouring out..hole in the upper rad hose caused by the fan hitting the hose at some point.

Correct Fix would be to pull the rad out and rebuild the radiator mounting system so the upper hose not so close to the fan.

However...not much room between fan and radiator and no fan shroud already and its been converted to 12v...I'm thinking take the fan out..install an electic push fan..so I'd end up with several inches of clearance between the pulley and rad face and not have to tear the car down

Do these engines run hot? Anyone else using a single or dual electic fan setup (6 w/twin-h)?

I'm not the right one to ask, because I have an aftermarket aluminum radiator. But the electric fan works great (I have it on the inside, as a "puller")- temp needle never moves once its up to temperature, rain or shine, hot or cold. I bought a termostat to plumb into the drain plug, to turn fan off and on depending on water temp- no sense in having the fan run all the time. I'm sure it will seldom come on at highway speed, and normal air temps.

Dan-

These modern day fuels burn hotter and slower than days gone by, when they burned quicker, and subsequently, with less heat output. I state that to answer your question: "Do these engines run hot?"

So, to answer your question, yes they run hotter than they used to, because of modern day gas. Modern day cars are designed to run over 200 degrees, but you don't want to do that with your Hudson. A couple of things will eliminate the overheating:

1. Puller fans work more efficiently than pusher fans (better to have one on the engine side).
2. If you have a stock radiator, it could be clogged up. These radiators were 3-core and you are WAYYY better with a four-core. Take one of your extras and have it re-cored as a 4-core.
3. Obviously, fix your upper radiator hose. Also, remember that there is play (if you have the stock radiator mounts) in your forward and aft movement on your radiator. You can get more movement by flipping the mounts over. There should be 7/8" between fan and radiator.

You must not have a stock fan, as I've never seen a Hudson fan so close to the upper hose.

4. 6-bladed mechanical fan (Haden's are the best) works better these days than a stock 4-blade Hudson fan.
5. Make sure your thermostat is working properly.

Lastly, to answer your last question:

I am running Twin-H w/single electric fan (and 6-bladed mech. fan), (w/condensor) on a 12V system, w/ a 4-core radiator and no shroud. With ambient heat of 111-degrees at the OK National, I never got above 165-degrees. It usually runs 155 or so.

Incidentally, these hotter running Hudson engines is the main culprit for Hudnut's complaints of vapor lock, whereas, that didn't use to be such a problem.

Hope this helps.

Popular junkyard fans are the Taurus, Lincoln Mk and Volvo. Google will be your friend here.

Forgot to add that any electric fan uses quite a bit of current. You will probably need to upgrade your charging system.

Thanks for all the replies, for now - electric fan on hold.

Motors solid enough, issue is not the original radiator, and someone cobbed the thing in place.

For now I made sure the engine wasn't moving around, and just got a replacement hose 12.00 vs..replacing the fan etc...what I figure is he was showing someone the car and they leaned against the hose/radiator top while it was running.

This new hose is formed so seems to give me just a skosh more room... but, the fan is still rat-rod dangerous with no fan-shrowd "Keep Your, Children, Loved Ones, and Hands And Feet Away While Running"...so this winter I may swap it out..but I'm going to drive it for now.

Do you by chance have a Hayden number for the fan you are using and does it bolt right on the waterpump?

Ken - Let me take some pics..show you where I'm starting from, then you guys can help me decide what I need..its a "rat-rod" pure and simple...I promise..I'll get some pics today!

Not to hijack this thread or anything, but, does anyone know what model Hayden fan works for Hudson engines and would it be the same for our '30 Essex six cylinder? I tried a plastic fan some time ago and the bend in the blades would contact the fan belt. Thanks.

There are spacers in various sizes to fix that issue,

PICS or it Didn't Happen!

That's a Mopar radiator in there with way to big a fan,

And the Radiator is too tiny - hence the street sign filler panel

Funny thing is I had a nice original radiator from the 50 Super 6, but I gave it away as I figured I'd never need it...heh, heh..jokes on me
