Thanks for adding the additional details.
They are important to understanding why your issue occurred and show that an aluminum fitting in an aluminum oil cooler isn't automatically a disaster waiting to happen.
(not arguing the fact that a steel fitting is a bit more forgiving)

Fair. The additional details were critical and should have been included.

It's worth nothing from page 5-34 (bolded shown on that page):

"While the manual has been crafted in such a way as to minimize contradictions between the instructions provided by Van's and the instructions provided with a part/assembly that is included in the kit (wheels and brakes for example), should there be an instance where the instructions from Van's contradict the instructions provided with a particular kit component, those of the component manufacturer shall take precedence over those provided by Van's."

When torquing the hoses to these steel fittings what is the right torque? I think it is a lot higher according to my handbook but it seems very high compared to the aluminum torque values.
