Freakin hilarious!

Tell me about the efan! Clutch fan would be more reliable for sure.
lol
been running efans for close to 15 years on ZJs...
I carry a clutch fan and shroud in the back just in case on my 94...
tired of it taking up the room so I might as well place it where it belongs...
and I think my efan might be needing a motor soon or the DC controls controller isn't spinning it like it should...
basically I'm tired of fing with them

The Mopar e-fan I have is less than a year old, I think it will last for many more years.
If my e-fan does go out the high performance Ron Davis radiator should help keep things cooled down, even the 1 year old stock Mopar one I have now should.
May have to keep my up speed or wait until night when things cool down, may even have to do some stop and go driving letting it cool off.
There's far worse things than an e-fan going out!!

The fan itself is not the only point of failure. Relays, sensors, fuses too. But just carry some wire so you can hook the fan directly to battery if needed.

Radiator came in. It weighs virtually nothing. Says Silla on the box. And the rad cap is much smaller than stock. I'm going to give it a shot.

Im actually pretty impressed with the Silla radiators, my buddy had one in his 5.9 when the stocker got mashed and I did the swap for him. The welds were nicer looking than the ones on yours but as long as they hold its a moot point, pretty doesnt always get the job done!

it worked great until he sold it as a parts rig about 6 mos later. I know it held up to his abuse and lack of maintenance for those 6 mos tho. They are a very nice piece for a cheap full aluminum radiator. Is yours the 2 row or 3 row? His was a 3 row and he paid $260 shipped iirc

I'll throw my nickle in.
For radiator C+R pricey but nice....
Oil cooler,trans cooler and steering cooler; Setrab... again pricey.
For Racing and Extreme duty the way to go...
Learned our lesson at the race track years ago, cooling is not the place to try to save money.
Recycling GRIFFY's to make beer cans gets old after awhile.

I was told 3 weeks and they don't charge you until it's ready to shipped out.
I searched around and was unable to find any other 5.9 ZJ running these.

Yea I didn't find too much innovation with the 5.9 cooling for radiators or trans coolers.

I tested my cooler that's bypassed the radiator out on a hot day off road around here and it gets hotter that it used to when it was plumbed through the radiator but it's still within operating parameters of the trans oil. It used to hang around 200-215 during hill climbs when the weather was cooler now it gets to 250 for short periods of time. This is still well within the temps of ATF-4 though but still higher than I want. The engine temp however has gone down a little. It's rated for 23,000 gvw. I am going to do one of two things....

I am taking the temp of the oil in the hot line after the converter.

1. Get this cooler that's rated for 30,000 gvw http://www.jegs.com/i/JEGS+Performan...60383/10002/-1

2. Or get a 6"-7" fan and bolt it to the cooler I am using now.

I am not sure how either of these will work out since the fan will push hot air from the aux cooler onto the condenser/radiator, and I'm not sure if the other cooler would preform any better in this heat, moving slowly off road.

So what's your opinion HighLonesome?
