In-Radiator ****** Cooler AND Standalone?

J-Thompson said:

explain?
the temps are cooler ,by a long shot
I am talking 95*+ and AC on
with instructions like
"if you want to make this climb under your own power you will need to find
the rev-limiter other wise take the by pass"

I dont see elevation effecting temps
not by that much
believe me if you wheel some of our trails in the summer it brings a whole new meaning to the term "hot as he77"

Thinner air and engine working much harder to make power equals more heat(PCM running the air mixture much leaner at higher altitudes),plus your version of steep hill climbs is 10-200 feet,ours can be over a 1/4 mile long.

No my version of a steep hill climb is bouncing off the revlimiter
Not many rigs will stand up to much more than a few hundred feet
Of that
Never gave much thought to the air mixture
Well guess that is just another good reason not to move

Well gang, as usual I'm late to the party... :badger_1:

From the looks of this thread others have used an '02 ****** with an '03 or later with the 42RLE and used both the in-rad ****** cooler and the factory standalone. So what I thought was an 'original idea' really isn't. Oh well...:smokin:

I found a Spectra Premium aluminum radiator that will fit my '03 and also has the fittings for the in-rad cooler like with an '02 with the 45RLE from RockAuto. Now to find what fittings to use on the trans fluid lines and the existing factory cooler so I can get a leak-free setup.

Any hints/tips for the fittings?

P.S. JThompson, remember that water boils the higher the elevation - and with lower air density at altitude there is reduced heat transfer from radiator to air. Check your manual; many things change under high-altitude conditions.

Check my sig
I live in south Louisiana
We consider 1000' above sea level to be high
and find that the air is to thin and dry so we stick close to home

Like Richmond, we're about 3 meters below sea level! We all get light headed when we go up a local mountain in North Vancouver!

Ah, yes, I remember it well!!

I spent a few years as a kid in Sulphur, west of Lake Charles along I-10. Nothin' but bayou, snakes, gators and Cajun gumbo - I gar-un-tee!! arty52:

Some of the best days of my life - and not a hill to be found! :smokin:

Hmmm, a thought occurred to me last night -

Seems I remember seeing some add-on engine oil or ****** coolers for racing applications, that were water cooled - such that you could tie them into the vehicle's cooling system.

Jegs and Summit carry radiator hose adapters, basically a short piece of pipe, with NPT ports for supplying coolant to other components, that install in the main radiator hoses.

In my case with the CRD, the engine plumbing is all wrong to use an 02 radiator, probably the mounts and attachment points as well with the intercooler added in.

But an add-on water-cooled cooler, and a couple of the above adapters installed in the supply and return radiator hoses...

If i remember right I used Chevy fuel injector fittings. I took the liberty to the parts store and he just let me try different fittings he had till i found some that worked.

Sweet!! I'll swing by my local NAPA tomorrow and see what we can work out with the Chevy injector workaround.

I love working on the Libby - it's like the truck asks me to tinker, update, make it MINE!! :gr_grin: :mexsmoke:

I agree working on the jeep is fun. Almost as fun as wheeling it. Almost.

A question for those who can answer.

Will a radiator for a 2002 KJ, automatic transmission bolt right into a 2004 Liberty
with automatic transmission?

Thanks
Jen

Bolts right up.

When I replaced mine (a Spectra Premium) for my '03 it has the fittings for the in-rad ****** cooler. Fitment specs are for an '02-'04 - found it at RockAuto.com.

Easy install...2 bolts and wiring connector for the electric fan, two bolts for the radiator, hoses and the rad support.

Thanks for the info guy's!

Along the line of extra ****** coolers, radiators, and cooling in general, if you've got any friends with JK Wranglers -

This past weekend, I and my friend just south of Austin (2011 Wrangler Unlimited Sport) tried a little experiment, and discovered a dirty little secret -

The viscous fan clutches and mechanical fan blades from our KJ's - the V6 and the CRD - will bolt on (actually, screw on) a JK Wrangler 3.8 L V6 without any mods whatsoever, with plenty of clearance - their water pump shaft is already threaded for the same type fan clutch.

We used the old factory fan clutch and 5 bladed metal fan I pulled off my CRD (replaced with a Hayden severe duty clutch and V6 nylon fan) to test for fitup. And if that metal salami slicer will fit, the V6 version will be a breeze.

Matter of fact, Hayden actually lists a fan clutch on their website, for 07/08 JK's, P/N 2738. And they can order it from OReillys for $47.

Now, we're trying to figure out which one of the factory fan shrouds to order to go along with a mechanical fan - gent in Egypt on one of the JK forums has pictures of his V6 JK, with the electric fan and a mechanical fan from the factory, with a one piece factory shroud that extends back over the mechanical fan.

So I'm gonna go ahead and run the ****** cooler lines into the rad cooler, then out to the factory stand-alone in front of the rad, then back to the transmission.

Question: How do I know which transmission line is the outlet and which is the inlet?

Since I'm going to add a new line from the trans to the rad cooler I want to be sure to get the plumbing going in the correct direction. This is the order I want to run the lines:

• Trans Outlet to Rad Inlet
• Rad Outlet to Standalone Inlet
• Standalone Outlet to Transmission Inlet

To do this I need to know how to identify the outlet and inlet lines to and from the transmission. Make sense?

Thanks in advance! arty52:

Run cold vehicle for about 10mins,shut off and feel both trans cooler lines.The cooler one is the return.

Check the ****** section in the FSM (for 05 it has a picture which identifies the inlet and outlet connections on the ****** itself), or stop by a ****** shop that's dealt with your type ****** and ask.

Infrared thermometer at Autozone for $30 - less painful and more accurate than your fingers!

Too :favorites68: ing simple!!

Here I'm looking for some identifier on the lines or...something.

The simplest answer is always the best - Thanks, Troy.

Damn it I like your advice. It's always uncomplicated and matter of fact.
