Wehrli 17-19 Duramax L5P OEM Location Coolant Tank - Gun Metal

When you're cleaning up the engine bay of your 2017-2019 Duramax L5P truck, the stock coolant reservoir can really stick out. Over time, these plastic tanks often become cloudy and yellow, looking like an eyesore. More importantly, the factory sensor inside them is not replaceable and tends to fail, leading to annoying false low coolant warnings on your dash. Replacing the entire unit just for a bad sensor is a common frustration.

This fabricated aluminum coolant tank from Wehrli Custom Fabrication directly replaces the factory unit in the OEM location. It addresses the aesthetic issues with a well-built aluminum construction that holds up better over time. Crucially, it includes a high-quality, float-type coolant level sensor that is easily serviceable. This means if the sensor ever does fail, you can replace just the sensor, saving you money and hassle down the road. The tank itself features a durable gun metal powder coat finish for a clean look, and it comes with a billet aluminum cap and an overflow hose.

This kit includes all the necessary installation hardware to get the tank mounted up. It's a solid option for cleaning up your engine bay and upgrading a known weak point on your Duramax L5P.
