Ok that truck was sold. Now i found with saying this as upgrades "6.0 Powerstroke diesel with arp, studs, egr delete, new oil cooler done about 1 month ago. Sinister diesel coolant filter so no more clogged oil cooler. Turbo off an 03 so it whistles pretty loud. 4" turbo back exhaust. " what should i ask and everything like that?
First thing, the Sinister Coolant Filter (or any filter for that matter) cannot prevent a clogged oil cooler. However it does help with its longevity.I really hate not being a gear head. half of this stuff is so confusing
