26 XL hydro cooler leak

[neoadman]

I have looked thru the topics and found a post from June 2018 for a leak that happens to be the same as mine 4 years later. The denso number is unavailable with nothing to supercede it.
My question is has anyone found a replacement for it or can this one be repaired?
With low pressure at the cooler could I just get a Hayden oil cooler and use hose to connect?

Why not get the OEM Mahindra one? They show it instock.
