Wehrli 17-19 Chevrolet 6.6L L5P Duramax OEM Placement Coolant Tank Kit - Bengal Silver

If you're working on your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra equivalent, and want to clean up the engine bay while addressing a known weak point, this fabricated aluminum coolant tank kit from Wehrli Custom Fabrication is a solid option. The factory plastic coolant reservoirs on these L5P Duramax trucks can become cloudy and discolored over time, detracting from the appearance of your engine compartment. More importantly, the integrated coolant level sensors in the stock tanks are not replaceable and tend to fail, leading to persistent false low coolant warnings on your dash. Replacing the entire factory assembly each time this happens can get expensive and frustrating.

This Wehrli kit directly replaces the OEM coolant tank, mounting in the original location for a straightforward installation. It's constructed from fabricated aluminum for a clean, durable look that won't yellow or become opaque with age. A key benefit is the inclusion of a high-quality, float-type coolant level sensor that is easily serviceable, meaning you can replace just the sensor if it ever fails, saving you money and hassle down the road. The kit also includes a billet aluminum coolant level sight glass, a black anodized billet aluminum cap, and all the necessary installation hardware and overflow hose.

This kit comes finished in a durable Bengal Silver powder coat to complement your engine bay. It's a well-built solution that not only improves the aesthetics of your truck but also addresses a common failure point in the factory cooling system, offering a long-term fix for the low coolant warning light.
