The Wehrli fabricated aluminum coolant tank for 2017–2019 Duramax L5P installs in the OEM reservoir location and replaces the cloudy, failure-prone stock units. It includes a serviceable float-type sensor to avoid repeated reservoir replacements, a billet aluminum sight glass and cap, installation hardware and an overflow hose. Finished in a high-quality powder coat, the tank cleans up the engine bay appearance while providing a field-serviceable sensor solution.
