6 volt Electric Radiator Fans?

[Powerhouse]

Anyone running a 6 volt fan in there cars? Just wondering if there worth the hundred bucks? Get's hot here in SoCal Day time...

Seems like MikeMaker has one on his P15 coupe, but Mike's been off the forum lately.

The electric fan only helps when the car is not moving. Anything over 30-40 MPH no fan (including the belt driven fan) is required. I have a thermostatically controlled electric fan set to come on at 190. I do not have a belt driven fan.

I put an electric fan on my 46 Ford pickup, and it functions the same as Mr. Coatney's, coming on automatically at 190. It keeps the engine nice and cool at slow speeds encountered in town driving, and has worked out well for me also. I plan to install similar setups on both my Plymouth coupe and b1b. Joel

I ordered my fan and control from a place called Southrods. I have seen them advertised in Hemmings from several places.

I am using a "HAYDEN" controller. Bought it from O-Rileys auto parts for about 40 bucks.

I should mention that I am running 12 volts.

Don't bother.

I used one for a year and found that they turn very slow at idle and low MPH using 6 volts. My electrical system is as good as it gets and I even have a 6V alternator. At idle when you need the fan the most it turns too slow at 6V, so what is the point if it does not turn max air at idle.

I talked to the folks a flex-a-lite. Turns out that their cheep nylon fan has a VERY aggressive blade pitch and it is only good to 5000 RPM. Perfect for one of our flatheads.

I had to make an adaptor to go from our large waterpump to the new smaller style one to mount the thing, no big deal, and it is working well.

best thing is it weighs nothing and no doubt will let the water pump bearing live a long time.

i have a 6 V fan on my 54 windsor and it has a switch inside so i can turn it on in slow traffic. it works well at keeping the temp good in hot weather. the car would overheat without it on 95 degree days. the only thing i have not done to the cooling system is pull the freeze plugs and flush out the block as much as possible. i put the fan on as a tempororary measure until i can do that, but it is one year later and i'm still using the fan. i got it from scotts cooling fans and i know it cost over $100 but it does work and it spins fast even at idle. dennis

neat...I think i'll control it with a switch...it'll be mainly for idling in traffic or at the MANY stoplights around here. WAY too many traffic lights around here, and there always on an incline or just at the end of a decline...makes driving an older car REALLY difficult.

Hey Capten29...How's the weather out there..I grew up in Holbrook and lived in Deer Park less than half year ago. Man...I miss the flat roads...TOO many hills out here...sure is pretty though. I heard they closed that Kohl's car meet thing...that was usually fun.

I have a question from those who have used an electric fan either 6 ro 12 volt on our type of rads, not modern rads, but our type of rads.

Now Don Coatney is corrrect, a fan does very little cooling after 40 mph, it is then airflow through the rad, anything restricting this, will impede efficient cooling.

Now my question is this, when I am driving my car, and its extemely windy, my engine will run warm to hot when going with the wind, and of course run cooler when going against the wind.

I attribute this to the vacuum effect, when going with a fast wind, the air, the wind resistance is lessened, thus creating much less airflow on the rad.

Now when going with the wind on warmer days, and I mean strong winds, would a pusher fan compensate for this and create more airflow across the rad at highway speed thus increasing cooling efficiency, or is my theory wrong?

On my 47, when the outside ambient temp is warm say over 65, and I am travelling with the wind, my engine can run up to 15 degrees hotter, when I go against the wind, or if there is a only a slight breeze in either direction, even on hot days, I run a normal 170 to 180 degrees engine temp, but as I have said, if travelling with a strong wind, my engine temp can go up to close o 200 on warm days.

Just thought maybe a pusher fan could compensate for lack of airflow in these situations.

Has anyone else experienced this with there cooling systems, am I overlooking another problem that may cause this?

Thanx Fred

This 1954 Plym engine I may be buying has a 6 blade fan.

I don't know if that's what comes on a 54 motor or if the

previous owner added it from something else.

It might move a little more air.

The 54 Plym did come with a fan shroud as original.

That may be a 6 blade fan......just can't see them all.

[Powerhouse]

just got the fan and installed it...seems to work ok...don't know if it does anything yet. I plan on using it when the temp get's high...as in traffic situations. It actually wasn't made in China...but it was made in ITALY.

Here's what I located on Scott's Cooling Fans. I didn't find a website.
