I've been wanting to complete my conversion (HD radiator installed, bought the oil cooler lines) but the hard lines won't clear the electric fans. Decided to abandon the project since my driving habits and distance probably won't get the oil real hot to need a cooler.
edit: I re-read your post about you ripping the front end and finding an oil cooler...you are probably looking at the P/S or ATF cooler. Oil coolers on 6.0L+ trucks are oil to water cooled so the heat exchanger is the the radiator.

The 5.3 has a small cooler on the front of the most forward radiator. It's got 2,full sized radiators then a small one roughly centered in the front one.
The c3,has the identical set up.
K. So if the oil cooler is water to air that small cooler on the front has to be something else.
I didn't get as far as to tracing the lines back to where they begin. It's quite possible that small one is power steering,I figure the 2 large ones were coolant and the tranny fluid but again I didn't trace the lines back.
Good points Steve. Your likely on the money with that post.
As far as cold we get as low as -40 here in the winter. -25c is the common high temps,which might be 20 grade territory however I've always gone thicker,never thinner.
Funny thing. When I changed the oil from redline 5w-40 to Amsoil 5w-30 cold oil pressure was unaffected,and hot oil pressure was only slightly lower.
K. When I get a good look at the fluid lines and trade them back I'll update what I see.
Thanks for the input gents.
Oh. Both trucks have the tow package which likely explains a lot of what I'm seeing.
