The Wehrli fabricated aluminum coolant tank for 2017–2019 Duramax L5P mounts in the OEM location and replaces the stock reservoir known for cloudy appearance and non-serviceable sensors. The tank includes a serviceable float-style low coolant sensor, billet aluminum sight glass and cap, installation hardware and an overflow hose. Finished in high-quality powder coat, it improves under-hood looks and simplifies sensor servicing over stock assemblies.
