Wehrli 17-19 Chevrolet 6.6L L5P Duramax OEM Placement Coolant Tank Kit - Flat Black

The factory coolant reservoir on your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, and GMC Sierra 2500 HD or 3500 HD, is known to become cloudy and yellow over time, detracting from your engine bay's appearance. More importantly, the non-replaceable sensors in these stock units often fail prematurely, leading to false low coolant warnings. Replacing the entire assembly just for a faulty sensor can be a recurring expense. This fabricated aluminum coolant tank from Wehrli Custom Fabrication directly replaces the OEM unit in the original location, offering a cleaner look and a more reliable solution.

Crafted from durable aluminum, this tank is built to last and features a high-quality flat black powder coat finish for a clean, stealthy look under the hood. A notable upgrade is the inclusion of a serviceable float-type coolant level sensor, which means you can replace just the sensor if it ever fails, saving you time and money down the road. It also includes a billet aluminum coolant level sight glass, allowing for a quick visual check of your coolant level without needing to remove the cap. The kit comes complete with an overflow hose and all necessary installation hardware, making the swap straightforward.

This Wehrli coolant tank kit is designed to address the common issues with the factory plastic reservoir. By choosing this well-built aluminum replacement, you're not only improving the aesthetics of your engine bay but also investing in a more dependable and easily maintained cooling system component for your L5P Duramax truck.
