My 2013 was losing coolant from the large hose connecting the cylinder head to the driver's side plumbing. I tightened these clamps (yes I know they're incorrect) and that fixed the major leak. But, a small amount of coolant was still being lost. I noticed some dried coolant residue on the coolant reservoir so I figured it was either bypassing the reservoir cap or the coolant hose connection at the front of the reservoir. I tied some paper towel strips around both. The strip at the small hose connection has now turned pink so I'm hoping that's it. Note the pink paper towel strip in contrast to the white one under the cap.
