Chevrolet 2500 Coolant Tank Kit - Wehrli - OEM Placement - Bronze Chrome - '17-'19. A direct-replacement fabricated aluminum coolant reservoir designed for 2017–2019 Chevrolet 2500 trucks with the 6.6L L5P Duramax, built to install in the OEM coolant tank location.

This Wehrli kit replaces the factory plastic reservoir with a durable, serviceable aluminum unit finished in bronze chrome. The supplied float-type coolant level sensor is user-serviceable, avoiding the common failure mode of non-replaceable stock sensors that can trigger false low-coolant warnings. The design cleans up the under-hood look while maintaining OEM placement and fitment for a straightforward swap. Included hardware and overflow hose make installation simpler, and the unit is produced in the USA.
