Can you take a picture as the rad in the lower part of the grill in front of the main water rad is the intercooler on diesels. Oil cooler is generally just a long pipe
As long as there is no hole you want loose pressure otherwise you might need a new intercooler good news its easily removed from underneath the bumper without removing any bumpers etc. Can be done on driveway with a jack and stands
