Fan upgrade?

Where do you get the thermostatic controll? I need one for my Efan swap.

Thanks
Greg

 

Hayden makes one. You can get them at a good flaps.
If you can wait till Monday I'll snag a part # for you.

 

I have nothing but time my freind. What is a "good flaps"? auto parts store?

 

Are you using a schroud?

 

I am going to begin searching for the stock 7 blade fan and see how much it helps. Next up will be a new radiator core, after that I will look into pusher fans.

I do have a question on coolent. Does having too much antifreeze hurt the cooling process? Also the lower hose absolutely refuses to seal up so it does drip some... I will have it sealed somehow before I am done but would the pressure drop effect temp?

Anyone here have an oem 7 blade for sale

Thanks, Chris

 

Ya im useing the schroud from the late model ford V6. Ill take a pic for you tomarow or the next day and post it.

Here is how the schroud fits. This is not mounted I just set it on top for the pic.

 

absolutely!
to strong a mixture can/will have the opposite effect
100% coolant is a big no-no..
colder weather extremes do require a stronger mixture though for winter use
a very strong mixture won't allow heat to be absorbed; the coolant becomes "heat saturated" and won't absorb any more.
remember that the water doesn't cool the engine directly; it absorbs the heat and carries it away to the radiator; the coolant raises the boiling temp of the water (in combination with system pressure), and lubricates and prohibits rust/corrosion in the cooling system components.

 

thanks, i know it has too much now since i dumped a gallon of antifreeze in and then only about 1/2 gallon of water would fit. So I guess I need to drain and refill correctly before I test it out again. That's actually ok since I need to get that hose sealed up.

I plan on testing it tomorrow to see if the lowering and correct mixture help any.

thanks, Chris

 

I converted to electric since I bent 2 fans in the water and lost radiators. I now have a 8 blade, 2speed ford hurricane fan off of a SHO tortise. Its on a thermo switch with a toggle interupter switch, no heat trouble anymore!

 

I might have found my 7 blade fan and it's even in colorado
They are physically checking the yard right now.
Keep your fingers crossed for me!

I too have tried just about everything over the years. A huge 7-blade fan from a 455 Pontiac with air mounted to a solid hub I machined to take the place of the fan clutch really did the trick........with two problems. First, it moved so much air that at idle I had to park in the grass or I'd pull up so much dust off the ground that I basically couldn't sit anywhere at idle lol! or everything/body around me got covered in dust, & second, it was very rough on water pump seals & bearings, especially if I hit water with it. I went back to a clutch fan as soon as I returned from CO after using that fan! I now use a plastic Ford ranger cluthc fan from a '90 (I think) & it seems to do fine, but of the two I've found the larger dia. is better. It was a bolt on as tehy both use a 5/8 waterpump shaft & slotted mounting holes. I have an electric pusher fan up front that's been used a lot since I shattered the shroud. I gotta build a new shroud as it really makes a huge difference.

I agree that a flex fan is a very poor choice for a vehicle used off-road with reletively high RPM's per ground speed as the fan pulls so little air in that condition.

 

Well they had the 7 blade but it was bent so they wouldn't sell it to me. He gave me leads on 2 other places that had one listed so I will have to call them and see. I went for a test drive and everything was great but... I can't really use the test since it was about 25 degrees cooler out today then it was last week. I even had to use the heater

A shroud would be the ticket I think. How do you make one?

Im really thinking about putting a electric in front of my hurrican . At windrock the coal in the mud was right nasty on the underhood goodies.

 

Is this the seven blade fan that you speak of?

 

That looks like the one I want although I have never seen one.
(is it for sale??)
