I just installed a NAPA clutch last month. In my opinion, it's not agressive enough. If I had it to do over, I would have gone with an OEM, or maybe tried a Perma Cool. OEMs are more than double the price I paid for the NAPA, but most say thay work better.

search for CRASH's recent posts. I would wait if you can for his GM fan clutch findings.

Hayden thermal - it's all I use. Probably costs about half of what I'd pay for OEMR here, and lasts just as long (~5 years.)

One of the designs I've got to finish is a fan clutch eliminator - I've had the one on the market pointed up to me, but I don't like it (just a bad design, y'ask me.) I think I can do better - "Look at that caveman go!"

Just one request . . . don't make it a hack 'n tap!!!

I really don't think I could stand those threads.

Hell, no. Everything I design is as purely "plug and play" as I can make it!

The less work that is done on installation, the better the job I did designing the thing.

I've got to finish my headlamp harness first...

I bought a hayden thermal from Advance and it was junk straight out of the box. Took it back and went next door to Autozone and got a heavy duty torqflo. It was larger and is working better. Both of these were around $36-38. Checked with the dealer, OEM was $135

Pulled fan clutch out, got the drill press....drilled a hole right through the center of it. Placed a bolt throught it, and spot welded the nut/bolt. No vibes, just cool.....


Not a DD by-the-way

Why wouldn't a person ( ok, me ) want a DD with a locked fan? What would be its disadvantages?

Little more noise, little less mileage, much better cooling. FYI Autozone has clutch spacers so you can remove the clutch if you want.

Yeah - but most of those are meant for flex fans (the extruded spacers,) and the rest are not something I'd want in a high-reliability, high-endurance application.

The FCE's I've seen are all cast - and they're "universal" - meaning that they've got holes in them that are much too large. And, they're cast to be "lightweight" - which means lots of grooves and corners that you just don't need.

I'm planning on having mine machined out of wrought stock, taking advantage of the grain flow of wrought material vice the amourphous grain structure of a casting (when you can anticipate loads, a cast part isnt' a good idea,) and having it "machined to fit" will make for a more PnP installation, and a part that can be lighter without compromising strength or fatigue life.

The first one I'm working on will work on XJ/MJ w/4.0, all years - and I'll have to see what else it will work on later. If need be, I'll design parts for the 4cyl and the V8 later - but that's later. I've got to finish the projects that are already on my desk now!

great....let me know...I'll take 2.

Mine was red and billet aluminum made by MrGasket
it fit real tight with no extra holes.

I used Hayden, medium duty.
