Wehrli 17-19 Chevrolet 6.6L L5P Duramax OEM Placement Coolant Tank Kit - CAT Yellow

If you're working on your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterparts, and want to clean up the engine bay while addressing a common factory weak point, this fabricated aluminum coolant tank kit from Wehrli Custom Fabrication is a solid choice. The original plastic coolant reservoirs on these trucks are known to turn 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 tanks often fail prematurely, leading to false low coolant warnings on your dash. Replacing the stock unit typically means buying a whole new assembly just to fix a faulty sensor.

This Wehrli kit replaces the stock plastic tank with a custom-fabricated aluminum one that mounts in the original location. It comes finished in a durable CAT Yellow powder coat, giving your engine bay a clean, uniform look. A key benefit is the inclusion of a high-quality, easily serviceable float-type sensor. This means if the sensor ever has an issue down the road, you can replace just the sensor, saving you time and money compared to replacing the entire tank assembly again. The kit also includes a billet aluminum coolant level sight glass and a black anodized billet aluminum cap for a well-built appearance.

This kit is designed as a direct replacement for the factory coolant tank and includes all the necessary installation hardware and an overflow hose to make the job straightforward. It's a practical upgrade that addresses both the aesthetic concerns of aging plastic tanks and the functional issues of their failure-prone sensors, ensuring your truck's cooling system alerts are accurate for the long haul.
