I took my 2013 5.0 R Spec to the dealer for routine maintenance at 40,000 miles. The service rep told me I was due for a coolant flush and injector cleaning. I told him no. The owners manual says to flush the coolant at 120,000 miles. Obviously he was trying to up sell this item. I can't find any reference to injector cleaning in the manual. Anybody have knowledge about this? Thanks
