Wehrli WCFab Fabricated Aluminum Coolant Tank Kit for 2017-2019 Chevrolet/GMC 2500/3500 HD (6.6L) Gloss Black WCF100433-GB

Fits 2017-2019 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD models (6.6L L5P Duramax).

The factory plastic coolant reservoirs on the L5P Duramax are prone to yellowing and clouding over time, making fluid levels difficult to read and detracting from the engine bay's appearance. More critically, the OE units feature non-replaceable sensors that often fail prematurely, triggering false low coolant warnings that require the replacement of the entire tank assembly. This Wehrli Custom Fabrication (WCFab) kit provides a permanent solution by mounting a durable, fabricated aluminum tank in the factory location.

This kit upgrades your cooling system with a high-quality float-type sensor that is fully serviceable, ensuring you never have to replace the whole tank due to a sensor malfunction again. Constructed in the USA and finished in a resilient gloss black powder coat, this kit includes a billet aluminum sight glass for quick level checks and a black anodized billet cap for a premium seal.
