Wehrli 17-19 Duramax L5P Coolant Tank (OEM Placement) - Chevy Orange

When you're cleaning up the engine bay of your 2017-2019 Duramax L5P truck, the stock plastic coolant reservoir can really stick out. Over time, these factory tanks tend to get cloudy and yellow, which doesn't look great. More importantly, the built-in coolant level sensor in the factory tank is known to fail, often leading to a false low coolant warning light on your dash. Replacing the sensor usually means replacing the entire tank assembly, which can get expensive and repetitive.

This fabricated aluminum coolant tank from Wehrli Custom Fabrication is designed to mount in the factory location and solve these issues. It's built from strong aluminum and finished in a durable Chevy Orange powder coat to look good and hold up over time. Unlike the stock unit, this tank features a float-type coolant level sensor that's easily serviceable, meaning you can replace just the sensor if it ever fails, saving you money and hassle down the road. It also includes a billet aluminum cap with a sight glass, so you can easily check your coolant level at a glance.

This kit comes with everything you need for installation, including the tank, a billet aluminum cap, the serviceable sensor, an overflow hose, and all the necessary hardware. It's a solid option for cleaning up your engine bay and addressing a known weak point in the factory cooling system.
