Oil cooler?

[jmfixitman]

Hi all, any mechanics out there that know what this box is? I thought it was the oil cooler, but when googling online I don't see anything like it. The pipe under it comes from my radiator lower connection, and back to the engine/recovery tank. Looks like two high pressure hoses on top of it.

This is on my 2009 Monaco Camelot with a Cummins 8.9L 425 ISL.

Thank you in advance!

Transmission oil cooler.

My transmission cooler is internal to the radiator.



Easiest thing to do is trace lines to see what it is cooling.

Same setup as mine. That is the transmission cooler.

Is tubing badly rusted? Are you out on the road? Oil ,trans and power steering cooling lines often rust through right under support/mounting clamp. Right before and after the clamp can be like new condition. If that's the case a compression fitting can make semi permanent repair. Provided enough slack to cut out with tubing cutter and splice.New line/s should not be all that too difficult to replace. All line repairs are just more time consuming than complicated. A line wrench is best to use. If old line nut is very difficult to break loose, you can break or cut line and use 6 point socket. Better than rounding off the nuts they are not really made of hard steel.
