Wehrli 17-19 Chevrolet 6.6L L5P Duramax OEM Placement Coolant Tank Kit - WCFab Grey

If you're working on your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterpart, and you're looking to clean up the engine bay, this fabricated aluminum coolant tank kit from Wehrli Custom Fabrication is a solid choice. The factory plastic coolant reservoirs on these trucks are known to get cloudy and yellow over time, which doesn't look great. More importantly, the factory sensors in these tanks often fail, leading to annoying false low coolant warnings on your dash. Replacing the entire stock assembly just to fix a sensor is a common frustration.

This Wehrli kit replaces the stock plastic tank with a well-built, fabricated aluminum unit that mounts in the original location. It addresses the common failure point of the factory sensor by including a high-quality, float-type sensor that's easily serviceable. This means you can replace just the sensor if it ever has an issue, saving you money and hassle down the road. The kit also includes a billet aluminum coolant level sight glass for a quick visual check, a black anodized billet aluminum cap, and a high-quality grey powder coat finish on the tank itself for a clean look. Installation hardware and an overflow hose are included to make the job straightforward.

This kit is designed to replace GM part numbers 84257137, 84214124, 84138913, and 84174037. It's a great way to improve the appearance of your engine bay while also addressing a known weak point in the factory cooling system.
