Decided to remove fan for winter and found these leaks. I'll take it to the car wash to get things clean enough to make sure only the hose ends are leaking. The FSM calls these quick-connects (they work as well the the fuel line quick connects near the fuel tank) and recommends special tool for removal. It sounds like what they describe is similar to an AC hose removal tool, which I have.

Does anyone know if the connectors can be made to stop leaking? I read a thread that used screw type hose clamps (Cherokee), and another KJ thread where the guy paid major bucks to a dealer to remove elec. fan, cooler, replace lines, etc, etc.

The radiator return hose is oily along with the sway bar (very oily. . . or would it be fluidy???) The oil spots seem to be located near the leaky connectors. Again, I'll clean things up and should know more.




BTW, the third time removing the fan was easy. . . due to the anti-seize on the threads.

PS Just got back from car wash. The top of the left hose is leaking where the metal connector was crimped (dirty looking one). That's the end the Cherokee was fixed by clamping, so it said. The other hose is leaking at the quick connect into the cooler. I pried the dust cap off it and the end wiggled around like it wasn't connected by anything. It felt like it would come out with a gentle tug. So, each hose is leaking. . . at opposite ends making replacement of both hoses necessary to stop the leak. I'll see what the transmission ends of them look like tomorrow. Hmmm. . .

TIA

You can carefully cut and pry the hose clamp/crimp gizmos off of the hoses with a Dremel cut off wheel and a screw driver. Then replace with quality transmission cooler rated hose with screw type clamps.
I had to replace them all on both of my CRDs during the 100,000 mile service.
I don't know if you can replace the O-rings on the quick connect fittings or not, check with the dealer. You will need a special tool to unhook the fittings.
One of my transmission lines flops around loosely at the cooler also, but it hasn't leaked yet (noticed it over a year ago).
I think that the rubber hose sections are not long enough to absorb the shake of the diesel engine. That said, I couldn't figure out a way to make them longer as there is limited room.

Eco tune, new rockers, and 5 volt glow plugs installed at 124,000 miles

It's probably not the connectors, but the lines into the cooler itself. I just pulled mine, connections were perfectly sealed, the leak was in the cooler. I sawed off the connectors and plumbed in an aftermarket cooler. I'm now leak free.

Which aftermarket cooler did you use? was it a good fit?

There are several posts on installing an aftermarket tranny cooler out there. Try http://liberty.eurekaboy.com/transcooler.htm or viewtopic.php?t=43019&postdays=0&postorder=asc&start=20 or viewtopic.php?f=98&t=44267&p=482204&hilit=cooler#p482204

At a glance those installs are a horizontal mount. IIRC there is a vertical (driver's side) example also but I don't immediately see the link.

The tranny coolers leaking are a pretty common thing to see these days. I ditched mine and put in an aftermarket cooler.
