Fan Problem

I have a 2013 Muscle with 2-1 VnH comp exhaust. I noticed that the top fan wasn’t running yet the bottom fan was. The bike was running around 235 with outside temp at 88. Any help would be great.

Both run on the same power source so likely a dead spot in the fan motor or related wiring to the top fan. Hook each one up to a 12v power source indivivually and check that way. Move the top fan blade in rotation and try it again. Keep fingers out of it unless unplugged.

Ron, it turns freely. Doesn’t come on when moving wires around. Do they make a high performance fan? Or an upgraded one?

No high performance I know of. Size restraints limits what you can work with in there. There are parted out fan unit's on Ebay. I'm thinking of getting a spare motor also, just to have in stock. Just to be clear, it won't run jumpered with a direct battery connection? If not, then the motor is pooched.

Yes do a search, I think the company is called spal you can get a fan motor and just change the connector. You can carefully press the fan blade off which in my opinion should only be done once. I bought a new fan assy from Harley and rebuilt my old set up w/ the spal motors. And yep the top motor failed on mines also. So I put some heat sheilding material zip tied to the back of the motor. The motor has already outlasted the old motor. Its to close to the header pipe.

Same exact problem with my 2103 Night Rod Special. My top fan runs, but not my bottom fan. It turns freely, but doesn't turn on. Have tried jumping it yet. Just put the bike in storage since I'm going on vacation for a couple weeks. Looks like I'll have something to tinker with when I get back.

They are noisy as in fast turning and moving air but unless you have squealing as part of the noise, it's normal.

Apparently from 2002-2003, the fans were two separate replaceable parts. But later models both fans are part of one larger unit and can't be replaced individually.eaning you have to remove, or at least partially uninstall the radiator to get the fans out and replace them. That's what it looks like anyway.

BUT looking at pictures of the units on eBay, it does appear you can swap out the fan MOTORS without removing the whole unit. They are held in by three screws to the fan bodies, and I think the screws face outward, toward the engine.

My bike is in the storage unit since we have some heavy storms rolling in this evening, but Friday I'm going to do an oil change on it. I'll look at it in person to see if it possible.

It may not save money, but it would save labor. I'll report back.

It is theoretically possible. But the fan blades are pressed into the motors. So they can't be easily removed from the assembly. Someone on here mentioned using a punch to carefully knock the pin out, swapping the motors, then pressing the fan blade back on.

I would up swapping the whole assbly without removing the radiator. But my bottom.fan stopped again, so something else is going on. I may look at disassembling the old unit just to see how easy it is. If I break a fan, so what, it was already toast. If it's easy enough, I can at least salvage the good motors as spares.

Yup, disassembled a working fan and pressed it into the assembly. Took all of two minutes to do, now I have two working fans again!

Hi all...I'm having upper fan problems for my '12 Turbo Muscle. Is it true that you have to replace the entire fan housing to replace just 1 fan? Or can you just replace the single fan? If I can replace the just single fan does anyone have a make, model, and part number you can refer to me? Thanks in advance!!!
