Wehrli 17-19 Chevrolet 6.6L L5P Duramax OEM Placement Coolant Tank Kit - Illusion Purple

When you're cleaning up the engine bay of your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD with the 6.6L L5P Duramax, the stock coolant reservoir can really stand out. Over time, these plastic tanks often become cloudy and yellow, detracting from an otherwise tidy appearance. More importantly, the integrated sensor in the factory unit is not replaceable and tends to fail, leading to false low coolant warnings on your dash. Replacing the entire assembly just for a faulty sensor can be a recurring expense.

This fabricated aluminum coolant tank from Wehrli Custom Fabrication is designed to mount in the original location, making installation straightforward. It addresses the common issues with the stock plastic tank by using a durable aluminum construction with a high-quality powder coat finish in Illusion Purple for a clean look. A notable improvement is the inclusion of a float-type coolant level sensor that is easily serviceable, meaning you won't have to replace the whole tank if the sensor eventually needs attention. The kit also features a billet aluminum coolant level sight glass and a black anodized billet aluminum cap, adding a touch of custom detail.

This kit comes with the coolant tank, installation hardware, and an overflow hose, so you have what you need to get the job done. It's a solid option for cleaning up your engine bay and upgrading a known weak point on your L5P Duramax truck.
