No, clutch isn't good enough.

now THIS is cool
was scratching my head for three weeks now how to get tranny cooler, ac condenser and rad cooler. We had several 118*F days here with high humidity... and my factory temp gauge was slightly above its normal position ... but not climbing further.

Most annoying was the drag on the engine when the stock fan clutch with the stock 5 blade fan was fully engaged. Even the idle RPM went up to 1200 in N and 1000 in D several times with my hotter engine. (would go down after a longer 50 mph drive with 4 TC locked and ~1800 rpm ... with the engine temps going back to normal)

I was even thinking about an additional washer fluid bottle, switch and nozzle in front of rad combo for these extreme "moments" ... will go with the 9 Blade Ford Fan ASAP

THANX !

got a 10 blade + fan clutch from the junkyard installed.


no comment on cooling yet, i'll reserve judgement for my next trip to the mountains. so far, idling with A/C on i'm not seeing a major improvement.

one thing I did notice is all the Explorer plastic fans in the junkyard had stress fractures in between the blades.


this one I got had the least amount of cracking...but others were very bad with complete cracks all the way across the surface between each blade. so watch out for that if you go the junkyard route.

I am going to see if I can research this for us 97-99 TJ owners. Maybe the Mustang clutch mentioned above will work. I would head out to the JY tomorrow, but its supposed to be 99 tomorrow. Over heating has always been an issue for me at slow speeds and runnig the AC is a Even at hwy speeds with my dumb electric fan.

I really want to do this mod rather than going back to an OEM unit.

Thanks for the awesome find!

I'm sorry I do not know. Chris142 came up with this mod and he works in a radiator shop, so maybe he can help when he logs on.

At some point, we will need to work up some part numbers for the various fan clutches. Hayden lists at least 3 different versions based on your temperate zone with regular, heavy duty, and severe duty being the options I've found so far.

I'm looking for a severe duty to swap in place of the OEM 7 blade and matching clutch as a comparison and it won't be from a salvage yard.

Over the next few weeks I'll be comparing this Explorer fan & clutch with the Autozone/Hayden Severe Duty with the stock 5-blade. Autozone's PN: 922791. They must have PN that will work with 7-blade...maybe a 1998 Dodge Ram truck 5.2/5.9L or a full size van?

They all do that! The metal that the plastic is molded to goes very deep. It does not seem to hurt the fans. I have seen them much worse and never seen one come apart.

Did you use the old fan clutch or buy a new one? Over time fan clutches lose their efficiency and any 20 yr old fan clutch is due to be replaced.

Does it seem to move air like it should? If it doesn't you will need to buy a new clutch.

The one thing I did notice Chris is that it does not suck a towel up the grill quite like yours is showing. Hmm!
