Many people insulate their tops here in Phoenix and report great results in their a/c performance.

People with soft tops just use rigid wall foam insulation stuffed between their roll bar and top. Guys with hard tops do a variety of different things to get better sound proofing and insulation.

And here's a profssional solution with some data about the subject.

Wow Thanks, was thinking of making my own but those look great, will have to put that on my shopping list, but still think Jeeps normal operating temps are to high, will still put a small pusher in front and switch at dash to use during the hottest months, cooler running motors, auto trans, a/c last longer..

Heck my 13,000lb motorhome runs cooler than my Jeep..

I do have a soft top and that is the problem. There is just no way the factory AC can cool down all of the radiant heat that is trapped inside. Wish there were some thing that looked good and worked to insulate the top.
A buddy of mine has his Bimini top on all the time. He puts the foam on top of the Bimini and then puts his soft top on over that. Then in the fall he just takes the soft top and foam off and the Bimini is still sitting there from last spring. You'd never know the foam was there. Also, it quiets down the ruffling soft top on the hi-way.

I just bought a 2002 wrangler and read this thread and thought this would be good preventive maintainence. Do you have to replace the clutch or can you use the one from the TJ?

Thanks

I went without A/C all last summer and it sucked. Finally got the condenser replaced and the system charged. It is so nice to have cold air blowing on me in the summer heat. I can only imagine it would get colder if I had the top on.

I am very pleased with the 9 blade/hd clutch upgrade. Not only does it fit better in the shroud, I absolutely hated the metal one. It looked crappy and just screamed "im gonna cut your fingers off b!$%&".

Well my friend tried the standard duty fan clutch with the 9 blade fan and he said it was like the stock setup as far as cooling. I didn't go anywhere today so he came by to borrow my setup again while he removed his clutch so he could swap it out for the severe duty one on his way home from work.

I'm waiting for someone to find a 3 wire, non-computer controlled fan clutch that will fit the TJ. Or find a decent pin out of the current electric fan clutches.

The early three wire clutches simply had a ground, a low on, and a hi on wire.

I'm certain I could figure out how to operate one of the newer electric clutches with two on/off temperature switches if I had a good pin out and signal requirement specs.

The more efficient fan blade is great, hats off to the OP!

But, I would still really like an electric fan clutch for two reasons; the higher end models have two different operating speeds (measured in % of shaft speed, not RPMs), and the ability to disable the fan for deep water crossings.

I'm sure I could find one to fit the TJ, the issue is finding all of the information needed to design a control system.

Electric fans simply do not move as much air as mechanical fans and their highly stressed electric motors tend to fail. So the obvious answer is a mechanical fan that is engaged electrically. Electric fan clutches have a much lower failure rate than electric fan motors.

Be very careful with the wife mod. Uninstallation can be extremely expensive. Wife mods have been known to take the Jeep and all other mods during the uninstall process. Also, make sure you service your wife mod properly as often as humanly possible. Wife mods not properly serviced may malfunction or uninstall themselves at any time.

As far as I know, most of those types of clutches are also tied to the computer module as well, in order to monitor open/closed loop situations and the temps ... I think making one for the TJ would be very tricky....

The newer Dodge trucks with the Cummins Diesel use an electronically controlled fan clutch. Some engineer goofed because the wires keep getting pulled into the blades and shredded.

Wranglers determine open/closed loop based off the temp coolant sensor, it would be no different than wiring an electric fan to an external controller that piggybacks off the coolant temp sensor.

The cost looks prohibitive for an electric clutch conversion... $120+ (low end) for the electric clutch itself. But then you need the control box as well. Something like a DC Control box - but custom for this application. Such a small batch item could easily cost $200 - $???. Then there is the appropriately matched fan as well - guessing anywhere between $40 and $100 for that.

Low end is $360, high end... maybe $700+. Those Dodge Ram electric clutches are $200 a pop.

Doesn't really seem worth it.

yeah, and e=mc^2 is pretty darn simple too. Now use it and go build a nuclear warhead.

There is more to it than just determining open/closed loop ....
