Question Hello All - New member and Question

Hello all, and thanks for the add.

I, recently, purchased a very cherry 2007 Commander; with 135k miles, and an impeccable service record, for $5k.
When I test drove it, I knew it had a bad fan clutch going in. No biggie, easy and cheap repair right?

Well I purchase the Autozone Duralast fan clutch, and have experienced the following.
Cold start engagement, then releases after initial warm up. (Great)
Then get in traffic, and it engages (as it should)
But here's where it went bad; it would never disengage, again, until a complete thermal cycle.

So I exchanged it for another, thinking, OK it's just a bad unit.
Well the second one is even worse. Stays engaged full time, no matter the temp.
However, the engagement is alot softer, and doesn't sap near as much energy as the last fan clutch.
But dang, it's a noisy fan, on this Jeep. I can't stand sounding like a Semi truck everywhere I go.

Long story short, do any of you have any good, low cost, fan clutch recommendations, or do I need to bite the bullet and go OEM?

PS: Other than the super noisy fan, I love this Jeep even more than my old 4.0 Grand Cherokee Laredo.
This thing is a beast, towing my boat. So effortless. And a very smooth ride to boot.

@Chris Walker; I don't really have what I would call a good answer for you about the clutch fan, but, I'm sure someone else here will eventually chime in; We have a lot of very knowledgeable members here.

The only advice I'd give you is this; More often then not, cheap replacement parts will come back to bite you, as you're finding out the hard way. You might be better off in the long-run buying a MOPAR OEM Clutch fan; It might cost you more up front, but, you will almost certainly have less headaches down the road.

Anyway, I just wanted to welcome you to the forum; Post some pics of your Commander when you can; Here are some links if you want to order any other parts for repairs or upgrades to your XK;

UPDATE: I returned the AutoZone fan clutches, and got the one at OReilly's.
Gotta say $15 more, makes all the difference.
It engages and disengages as it should.
No more heavy power draw, from the fan, no more excessive noise.

Today was a good test day too. At about 100 degrees, outside, the Oreilly's fan clutch performed superbly.
No overheating, in heavy traffic, and no excessive fan noise during acceleration, and no excessive power draw of HP.

AutoZones $45 fan clutch = utter failure
Orelly's $70 fan clutch = Total win ... time will tell if it lasts.

Gotta say, for years I've used DuraLast brand products, and never had any issues with the starters, alternaters, waterpumps, etc. But they definitely do not know how to make a fan clutch.
