No i have a 5.7, protects from chaffing/rubbing debris its designed to replace the inner hose and be used again..
Nicjak: I think we are taking about different items. I understand the covering on the hoses. That makes sense. It's this silly pink rubberband on the right side of the radiator weakly holding together the 3 hoses. I was wondering if anyone with a 2015 ecodiesel has this rubberband. It will not last with the underhood heat. Just seems a little rinky dink. Don't want to tie anyone of you up on this crazy topic anymore. It just seemed wierd. Thanks all for your comments. MIke
