Fits: 2001 thru 2007 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ Duramax Diesel

This cooler line clip attaches to the right side of your engine block and keeps the cooler lines secured. These clips break often and allow the cooler lines to come loose and possibly get caught in the steering idler arm causing damage to the cooler lines. This is a simple replacement with only a 10mm wrench needed. If the nut is missing that holds the clip to the block it is a 6 x 1.0 metric with a 10mm head.
