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

If you're working on your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterparts, and you're looking to clean up the engine bay, this fabricated aluminum coolant tank from Wehrli Custom Fabrication is a solid choice. The factory plastic coolant reservoirs on these L5P Duramax trucks are known to get cloudy and yellow over time, which doesn't look great, especially when you're trying to make your engine bay shine. More importantly, the factory sensors in these plastic tanks often fail, leading to annoying false low coolant warnings on your dash. Replacing the stock unit usually means buying a whole new assembly just to fix that sensor.

This Wehrli tank addresses both the appearance and the functional issues of the stock coolant reservoir. It's fabricated from aluminum and mounts in the original location, making installation straightforward. A key feature is the inclusion of a high-quality, float-type coolant level sensor that's easily serviceable, meaning you won't have to replace the entire tank if the sensor ever needs attention down the road. It also includes a billet aluminum coolant level sight glass, so you can quickly check your coolant level visually. The tank comes finished in a durable Bengal Blue powder coat and includes a black anodized billet aluminum cap, installation hardware, and an overflow hose.

This kit is designed to replace GM part numbers 84257137, 84214124, 84138913, 84174037. It's a well-built solution that improves the look of your engine bay and provides a more reliable and maintainable coolant level sensing system.
