Hi guys,

I did do a search and found one big thread on this but in the end it still wasn't clear, with all the posts about using gloves on spinning fans and all...anyway, when I turn my fan by hand when it is cold, it doesn't spin freely, there is a slight resistance. But I don't hear any "roaring" when she starts up, either. What is normal here? Do I need a fan clutch? Thanks,

Lindsay

Sounds normal. Just because you don't hear a roar doesn't mean its not working. If your engine temps appear normal on really hot days and your AC is working okay, then its probably working based on your description.
 
I had a similar situation as you do not too long ago. Clutch that seemed to have resistance when cold by spinning the fan but no roar at startup. I was changing the belts and decided to pull the fan out and check the clutch. After I got the clutch out and removed the fan, I held the hub and spun it using one of the studs. After about 3 revs of the clutch ALL resistance would dissappear and it would free spin with 0 resistance until I would quit spinning, and then it would continue to freewheel for a couple of revs till it stopped. I never had an overheating problem living here in San Diego but I can tell you there is a night and day difference with the amount of air moved with the new clutch over the old.

If I had never taken it out I would have never known how bad it was!

Which brings up a good point....even if it appears to be working, for what it costs, its definitely worth swapping out for a new one at 100K miles. And FWIW, I have had crappy luck with aftermarket clutches. Only OEM for me.

You can tell little to nothing on the condition of an OEM fan clutch by turning it by hand with the engine off.

All OEM fan clutchs are blue now per Dan.

We have been doing testing on the fluid level and internal adjustments of OEM fan clutch and could use some more used fan clutchs (blue or black) if anyone is interested in donating to the cause.

I still have my original clutch (black, made by Eaton I believe) it is yours provided you will in good faith attempt to gather info on these clutches and present the info back to us hopefully with a possible fix for bad clutches.

PM me a shipping address.

Ditto this. Although I can count on one hand how many times the fan has come on in the 1 1/2 plus years I've had this rig, I wasn't sure she had gone soutn until I did the "stop the fan" test. Doing the fan clutch test is simple and showed my was not working properly. Take a bath towel and roll it up. Let the end rub against the fan blades. Your hand doesn't have to be anywhere close to it. If the fan stops under the light pressure of the towel, then it's time for a new one. It blows for about two seconds everytime I start it up now, so I know she's working.

The new number is navy blue. The older one is black and I have seen at least one "natural" colored, a sort of silverish.

My "new" blue one, two years old, is crapped out I think. I ran a bit warm on this last trip on a couple hard pulls and I was not hearing the fan :mad:
 
I just replaced my fan clutch...er had it replaced as part of an A/C diagnosis. The A/C would not get cold...plenty of freon charge but the fan clutch was at fault: It would not pull enough air past the condenser to get really cold...especially at lower speeds/idle. A/C works GREAT now!
