Wehrli Custom Fabrication Gloss Black Fabricated Aluminum Coolant Tank Kit for 2011-2016 Chevrolet/GMC 2500/3500 HD (6.6L)

Fits 2011-2016 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD models equipped with the 6.6L LML Duramax diesel engine.

The Wehrli Custom Fabrication (WCFab) OEM Placement Coolant Tank Kit replaces the fragile, discolored factory plastic reservoir with a heavy-duty fabricated aluminum unit. Designed to bolt directly to the factory mounting points, this kit cleans up the engine bay while providing superior durability against the heat and pressure cycles of the cooling system. Each tank features a built-in sight glass for quick fluid level inspections and a custom powder-coated Gloss Black finish.
