My tranny cooler lines are rotten, unfortunately nobody makes them any more, id like to keep the heat exchanger, due to the fact that I live in a climate that regularly goes below -30. Just curious what my options are????

Thanks

 

You're referring to the metal tubes that carry water/antifreeze to the heat exchanger?

 

Yep, one was rotted right through, the others are not far behind. I have a good heat exchanger, just wondering what my options are for replacing the steel lines?

 

This old thread has both the Cummins part numbers and some suggestions on making your own.

Cummins doesn't tend to discontinue parts. If you don't have a Cummins shop near you, then Cummins Power South here in Atlanta (404-527-7800) will be happy to ship them to you.

Thanks, ordered the parts through cummins today. The part numbers have changed but the parts guy @ cummins was able to find them from the original numbers. I will post the updated numbers as soon as I get the parts.
