Yet another update: Dealership received the part but wait... they need the o-rings and the isolators for the install. Which isolators are on back order due in January. So I get to drive in a ticking bomb? Since the EGR cooler leaks coolant into the exhaust system at a rate of about 2 gallons a week at 20.00 a gallon I asked who will pay for that? FCA Customer Service said "I need to monitor the coolant level and fill as needed". .. We'll at this point I want to crawl through the phone & ......... So I'm at point of what to do? Truck needs to get fixed,,, it's under warranty but no parts... Dam !!
