Well, thats it. Looking for a good thin fan for the mustang. I read a big indepth thread on some other forum about how when the drag from the fan is gone it helps the engine run smoother and when in stop and go traffic it throws more cfm and i like how it comes on at one temp then off at another or how when you turn the AC on, it comes on as well.

I just dont know which one to get. There are so many! I was really looking at the Derale after some really good reviews on cfm and fitment but i dont know much about this area and was looking for others to chime in. I live in 100-120+ degree Az heat so the cooler the better.

This issue im having is i upgraded to a 3 row radiator (autozone brand) from my orginal 40+year 2 row. That with the Redline water wetter really does the trick, but now my shoud wont fit (one extra row wont fit the shroud brackets) and im looking for anything to get ahead with helping this unrestored engine run as long and as smooth as possible. Anyone have and suggestions or thought on elc fans. Also, are they hard to intall? Should i take my radiator off mount then reinstall or can i do it with the rad in the car?

Anyway, here is what i was looking at...

Derale 16926 Derale High Output Single Automotive Electric Fans

I measured between my rad and the water pump and it will fit easily, so...?

A fan about the size of your old one will be good. But the biggest one that you can fit in there is the best idea. I don't remember what the CFM was that you need but those fans haul a$$ and they go faster than stock fans so it should cool better.
I was wondering about the 3 row radiators? Are the cooling tubes 1" long?
Thanks and good luck.

David,

I really dont know. When i put the two next to each other, they looked identical. I never thought to check the thickness. But whatever it is, its just enough for me not to be able to use the factory brackets.

I think the thickness is the tubes length when you look inside the tank you will see the slits in there for the water to flow through and if they are 1" in one direction and there are 2 or 3 rows. I think with the 3 row one you don't have 1" rows.
The one your looking at there looks like a good fit.:bigthumbsup

I bought a 16 inch electric fan from Speedway. It has about 2400 CFM.
I went with a aluminum radiator from a 67 that is 20 inches wide. Have a coolant overflow/reservoir tank.

Car does not get hot even when idling in 100 degree heat
Here are pictures and info: Cooling

Good Luck and BE Safe

Nice job. That looks like how it is done.

I have the flexalite black magic electric fan it fits my 65 like it was made for it. It is on the thick side, I have an aluminum radiator so I'm not sure if it would fit you car. It pulls 3000 cfm and had a built in relay and thermostat for a real easy install. In summer in 105f heat it runs at 180 even in bumper to bumper California traffic. In winter she warms up much quicker also, giving me heat quicker.

FLEX FANS and Clutches?

Well, i dont have any bumper to bumper traffic here. Its a very small town. Also after some research, it just might be easier and less of a hassle to do a flex fan. A couple of questions...

There are alumn, stainless steel and nylon models available. Which one would be the better choice (not a daily driven car, maybe 500-800 miles a year) and do i still use the clutch that is on the original fan? If so, what is the difference between thermal and non thermal. Is one better then the other?
