WCFab Fabricated Aluminum Coolant Tank Kit for 2017-2019 Chevrolet/GMC Silverado/Sierra 2500HD/3500HD (6.6L) - Gloss White - WCF100433-GW

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

The factory plastic coolant reservoirs on the L5P Duramax are prone to yellowing and becoming cloudy over time, which detracts from your engine bay's appearance. More critically, the OE units feature integrated, non-replaceable level sensors that frequently fail, triggering persistent false "low coolant" warnings that require the replacement of the entire tank assembly. The WCFab Fabricated Aluminum Coolant Tank Kit addresses these issues with a durable, American-made solution designed to mount in the factory location.

Constructed from high-quality aluminum and finished in a Gloss White powder coat, this kit features a serviceable float-type low coolant level sensor and a billet aluminum sight glass for easy fluid monitoring. This design ensures that if the sensor ever fails, it can be replaced individually without discarding the entire tank. The kit comes complete with a black anodized billet aluminum cap and all necessary installation hardware.
