So I replaced my oil cooler about 4 weeks ago. After an 1100 mile trip I had the wrench light again and a 40'delta. So I attributed that to the VC9 flush possibly clogging the new one up. So I changed it again last week and now 100 miles later I am getting 30-40 degree deltas. Is there something that may be causing the high oil temps other than the cooler? Thanks for any help. I am monitoring with a CTS and the truck is an 05 with 99000 miles and it's 5th oil cooler
