Steering Oil Cooler

[SVX ROO]

My steering fluid cooler started leaking, first thought it was just at bend next to the return hose but it turned out to have other leaks along the length of it.

Anyone else had this failure?

I made a new cooler from 3/8" copper tuping and mounted behind and slightly below the radiator. It does not get the coolest air but it will get good flow around it and copper will transfer heat better than steel tubing. Anyone see any problem this might create?

Can anyone tell me about the standard part? Is it just a single U-shaped tube or does is have more than one pass across the car? Does it have any fins?

Has anyone changed one? What did you have to remove to do it?
