Was looking for some insight. Recently had the Ipr remote oil cooler and coolant filter installed on my 04 6.0. After getting my truck back from the shop I realized that the return and inlet hoses coming from the coolant manifold were backward and the hose coming from the filter to the oil cooler was on the outlet in stead of the inlet. I was seeing 20+ degree deltas unloaded while on the interstate before I realized that it was all hooked up backwards. Anywho I corrected the hoses and cleaned the heck out of the coolant filter but I’m still seeing 20+ degree deltas while driving. I’m starting to lean towards the oil cooler being clogged which sucks because it may have 500 miles on it. Anyone else ever went through this? Is there a way to backflush the remote Ipr oil cooler? Any help and advice would be greatly appreciated! TIA!!
