Wehrli 17-19 L5P / 2019+ L5D Duramax OEM Placement Coolant Tank Kit - Semi Gloss Black

If you're working on your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, or the 2017-2019 GMC Sierra 2500 HD or 3500 HD, and want to clean up the engine bay, this fabricated aluminum coolant tank kit from Wehrli is a solid option. The factory plastic coolant reservoirs on these trucks are known to become cloudy and discolored over time, which can really detract from an otherwise clean engine compartment. More importantly, the sensors in the stock units often fail, leading to false low coolant warnings on your dash. Replacing the entire factory assembly just to fix a sensor can get expensive and repetitive.

This Wehrli kit addresses both the appearance and the reliability issues of the OEM coolant tank. It's constructed from fabricated aluminum and mounts directly in the factory location, making installation straightforward. Unlike the stock unit, this tank features a high-quality, easily serviceable float-type coolant level sensor. This means you can replace the sensor if it ever fails without needing to replace the entire tank, saving you time and money down the road. The kit also includes a billet aluminum coolant level sight glass and a black anodized billet aluminum cap for a clean, finished look. The semi-gloss black powder coat finish is durable and resists corrosion, helping to keep your engine bay looking sharp for years.

This kit comes with the coolant tank, installation hardware, and an overflow hose to get you set up. It's a well-built replacement designed to improve both the look and the long-term reliability of your Duramax truck's cooling system.
