Yes I have a front cooler

The ones that are leaking are the 2 that run up to the cooler. I’m confused about the with or without rpo code

1 has a trans cooler, the other doesnt. Look in your glovebox for rpo codes
Better yet tell me, do you have a trailer brake controller, from the factory, by your left knee?

No I don’t have a trailer brake controller

Look in your glove compartment and see if you see these 2 codes KNP K5L

Ok I’ll have to take a look later. Was hoping to get those out in today....might not be happening

No I don’t have a trailer brake controller

So k5l is out, do you see knp?

The transmission cooler lines are known to be a problem area. There are threads around like this: http://www.cadillacforums.com/forum...ssible-quick-cheap-solution-crappy-leaky.html that show how to fix using some fuel injection hose and double hose clamps.

I did this to my Esky and not a drop in almost 2 years. Much cheaper and likely lasts longer than replacing the hoses that are still prone to leaking at the metal to rubber junctions.

Is yours a 07+ I just read that and they did it for earlier model

 

[sk1dm4rk]

Yes. My Esky is 07. They went over the top in that link. All I did was use a small pipe cutter to cut behind the rubber/metal junctions and got a couple feet of Fuel injection hose and hose clamps. There is not much pressure in those lines. The double clamps seal it up, so no need to flare the metal ends or anything.

Done. Cheap. Better.

Did you take the lines out or leave them in while you did it? I like to see a how to with the pictures

I posted a couple pics there.

I left the lines in place. It literally is as easy as I said before. Use the cutter and clamp the hoses in place.

The good thing about this is that if it doesn't work for you, you are only out $20 and you can either find another solution or order the OEM hoses.

Good luck

Yea Napa has the ones I need in stock I’m pretty sure. I’ll have to see how rusty they are when I get under there in a bit if they aren’t then I’m gonna try this. Just not sure if I should flare them or not.
