This is off a tractor. A CAT D4 Hydrostat. Very big! Cracked and leaking from the bottom.
Is it steel, alumunum or copper?
Depends on the style of cooler and where the crack is. If is in a tank they can usually repair it if they can get to it. Make sure they know what they are doing if they have to weld or braze it. It should be cleaned and have nitrogen flowing through it while welding to prevent turning and oil into carbon that could contaminate the system.
It is heavy, so thinking copper or steel. I believe they will be able to get at the leak as we could see it from below, but it's right where the fins enter the lower solid assembly.
Thanks for the advice about nitrogen.
I shutter to think what one of these puppies would cost from CAT new.
