2008 h3 alpha fan clutch

[Jeasen]

Previous owner had the water pump replaced but old fan clutch is still in place. I want to replace the fan clutch but GM has discontinued part #25844696. What are you guys using in its place? I tried doing a search but nothing came up?
None of the parts listings shows an alternate. Rock Auto shows a water pump with a fan clutch attached but I already have a new water pump.

Have you checked Hayden? I think they still make them for the H3.

We ran their HD option on our 6.0L H3

I did but it seemed to be for the H3 and did not specify for the Alpha.

I went to the Hayden website and found that the Hayden part number for the 5.3 Alpha is 2841. Rock Auto has it listed on it's site for $103. Thanks rascole and ATVspeed4 for the tip.

The Hayden one is actually a heavy duty one which will give you better performance over OEM. That being said, if for some reason you want the OEM one, I actually do have one used. Has less than 1000 miles on it. I bought it back a while ago, but then I upgraded to the Hayden one.

Yes, can confirm the Hayden HD works well. Got it on 3.7l 07 H3.

This heavy-duty fan clutch is what I'm using in my vehicle. https://www.rockauto.com/en/moreinfo.php?pk=1793624&cc=1441263&pt=6812&jsn=585

Thank you all for your help with this. I have the Hayden 2841 on order.

Question, is the loud “semi-like” sound when accelerating from the stock clutch fan? Or just normal for the Atlas engine?

The HD fan clutch will make more noise. It's all the air moving, that's a good noise.

I like the sound, definitely set it apart from other vehicles. Just read some others saying it was a bad fan. Thanks for the info.

The HD Fan Clutch quiets down after a few months of driving.

SuperModulation SFan4500 Efan here, no clutches needed....

Do what you want, but I don't like Efans. There's no such thing as free power. Mechanical clutches don't need any thing to work but physics to work.

I’m keeping my oem fan. It seems some people (not on here) were saying the low fan noise was a defective clutch fan, but I’m finding out it’s just the nature of the fan. Thanks for the responses everyone.

I hear ya. Efans are not free to power, but they are when they are not running. Like all Winter long up North... What they do is free up power that the OEM fan sucks up all the time the engine is turning and more so when hot. That is why nearly all new trucks have Efans.

When I used to drive the 07 in the MI late Fall, Winter, early Spring, the fan might come on a couple times a month. My 09 Alpha is parked for Winter to keep it's no rust that way, but on those cold dry days when it is on the road, the Efans never come on.

E fans are great, if you have modern OEM e fans, like the 800 watt JL fan or Camaro fan. Aftermarket e fans just don’t move enough air.

Say what? There are several Efan kits made for the H3, buy the right one and it will move plenty of air sufficient to cool a Cam Swapped Alpha with AT.

Is there a Severe Duty Hayden fan clutch for the H3 Alpha??? I tried to find something on a 5.3L in the catalog but was unsuccessful.

I'm in Arizona and run hot anyway so I'd prefer the Severe Duty. I used to run 1 on my 8.1L 3/5 ton Suburban in the summer. It literally ROARED, and slammed the temp gauge down!!!

I'll try and call Hayden tomorrow.

Later,

Matt

Where do you live?

Called Hayden, worthless, just some mouth breather who looked up my vehicle in the e-catalog. "nope, no SD fan clutch for this vehicle."
