Wehrli Custom Fab OEM-placement coolant tank for 2017–2019 Duramax L5P trucks replaces the stock reservoir with a fabricated aluminum unit finished in sparkle copper. It includes a serviceable float-type sensor to avoid repeated full-reservoir replacements when sensors fail and adds a billet aluminum cap and sight glass for easier monitoring. Designed to clean up under-hood appearance while addressing a common factory failure point.
