Ok I am going to attempt to fit an oil cooler to my 08 gear up.
I plan to keep the cooler at the same level as the bottom of the filter housing. probably mounted low on the nose of the tub.
The photo showing the oil cooler on top of the crach bar is too high me thinks due to the low oil pressure the Urals run, keeping it at the same level as the filter housing should minimise any pressure problems.
I got the adapter only from the dealer as it was cheaper to ship, hoses and actual oil cooler will be sourced locally.
The oil cooler is an aluminium dual pass unit that dissipates heat better while no air flow is available, which is when you need it most.
I will post furtner pics and any temperature variance as noted.
