Default Re: Trans cooler bursts!

I run a functional cowl hood scoop over the hole we cut where fake vents use to be.

It would have quite a bit of header heat as well as radiator etc. heat going out the scoop. There are many places to add different sizes of coolers even if you need to add a fan if you do not get normal air flow.

from the picture it looks you also remove the small trans cooler and brackets to mount the 4739-1 . and use some the mounting holes of the old trans cooler to mount the 4739 .and than you need to plug all 4 lines to the rad.

Yes replace the smaller cooler with the 4739. I used one hole(top drivers side) from the old cooler. Drilled one new top pass. side. The bottom 2 used brackets that come with the 4739.
As for the radiator. I just by-passed completely. There are 2 lines (one in and one out) they are looped by just clipping the exsisting tubing and looping a short pc of the tubing which comes with the 4739. The 2 lines which came from the rad go to either end of the new cooler(cooler is not directional) this completes the 4739 loop and we are good to go. Very simple.
I found that keeping the connectors in place and clipping the tubing, the supplied rubber hose slid over the exsisting tubing as a perfect fit..

I looked all of this over today and I would not just loop the oil cooler lines on the drivers side. There is so much room over there that you might jut as well add a small cooler, or clean out your factory tranny cooler and mount it over there.

On another note- how many of these trans coolers are bursting, and are they bursting on the 03-04? or newwer? We added a second tranny cooler and a fan on a 1500hd this weekend... the second cooler was unnecisary, but the small 8" fan rocks..... Set up on a thermostat....

The issue is not in the trans cooler itself. It is in the side resi of the rad where the lines pass through. These are located on the passengeer side of the rig. The larger tubes are located on the drivers side, which go to the engine block....thinking some kind of oil cooler. I didn't touch them.....trying to investigate if anyone had any issues with this bursting, causing oil to mix with antifreeze......that would suck! If no issues I plan on leaving it alone.
