71 mustang 351c adding clutch fan
#1
New to the site. I’m sure it’s been talked about before but I’m wanting to put a clutch fan on my 1971 mustang. 351c. Ac car. What fan and clutch is everyone using? Thanks

I have switched several of my rides over to this fan, they work great and look like they belong there. There is a link to the clutch to use with this fan below in the description. Also welcome aboard.

Hi and welcome from Michigan. I did this last year. The originals are dangerous and they can break. If you go to the search tab and type in clutch fan, you will find a lot of different threads about it. But the best one is check your fan blades. There are a few different links from Hemikiller for the deralie fan blades and the Hayden fan clutch.

Hello and welcome from SW Ontario.
On the 71, it would have had a 4 blade fan. I'm not totally sure when Ford switched to 5 blade flex fans, but I think these are what jpaz is referring to. These are definitely dangerous and need to be chucked in the nearest scrap bin. I worked at the factory where they were made and have seen the damage they do WHEN they blow up on test rigs.
Definitely research for the absolute best clutch fan set up out there if you want to go that route and are not concerned about originality.

Ooops, you said A/C, missed that, so your car may have had a different fan.

Here's the parts needed for a clutched fan conversion.

The clutch you need is the Hayden 2710. The fan blade is Derale 18" 17118. You'll also need a stud kit, as using bolts in this application is a serious lesson in frustration.

Are these the same parts for other engines as well? I am thinking 429/460 in our cars.

429 cars used a 19" fan. Clutch and studs should be the same, unless there is a clearance issue and you'd need to peruse the Hayden catalog for a shorter clutch. 19" fan assuming you're using a factory 429 shroud, otherwise use the 18" I linked to.

I had to use the Hayden 2947 on my 460 due to clearance issues at the radiator. It is so low profile that it is very difficult getting the nuts on the studs but with patience it can be done.

Wow - I guess I got lucky or something.  I'm using a monster 7-blade unit my buddy Jim gave me - I have no idea what it came from, except maybe his 1963 1/2 Galaxie 500 with a 390FE.  Bolted right up - no issues.  I think there is barely 1/4" clearance on the factory fan shroud - could be a big reason why mine stays so cool. I know when I didn't have the windshield or hood gasket installed, and I was moving the car in and out of the garage, the air moving from under the hood would blow my hair back sitting in the driver seat.
