Urgent Help! Pinhole Leak in ATF Cooler

[gohawks444]

Have a pinhole leak in the ATF cooler where the nipple comes out to connect to the hose. The shop told me the only answer was a new radiator. The welding shop told me that they would only work on it outside of the vehicle.

Any other options???? Help please

What model and year do you have?

get some JB Weld and see if that fixes the problem.

That'll be the quick and easy fix. If the crack is too big, then just replace the a/t cooler since they're only 25-50 bucks I think (depending on the size).

GOod luck

so they don't have to remove the entire radiator? Just the cooler on the bottom?

quote from welding shop was:
$65 to remove and replace the radiator
$40 to silver solder the crack

best way to fix a crack is to remove it and dry it before using jb weld or soldering it.
but if the crack is too big, it's easier just to replace the entire cooler.

sounds expensive for what they're doing actually (but then again what's a few bucks when you gotta add fluids etc etc.)

not to sound like a moron...but since I am one when it comes to working on cars I will ask anyways.

Is the cooler we are talking about actually part of the radiator or a separate part altogether.

There are 2 hoses that run into the cooler that attach to two nipples. I can't really tell if this is separate from the radiator or if is part of the bottom of the radiator.

Can't seem to find it in my repair manual.

thanks again.
