Wehrli 17-19 Chevrolet 6.6L L5P Duramax OEM Placement Coolant Tank Kit - Brizzle Blue

This is the Wehrli Custom Fabrication coolant tank kit for your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, or GMC Sierra 2500 HD or 3500 HD, equipped with the 6.6L L5P Duramax engine. It's designed to mount right where your factory coolant reservoir sits, offering a significant upgrade in both appearance and reliability.

The factory plastic coolant tanks on these trucks are known to get cloudy and yellow over time, which doesn't look great in a clean engine bay. More importantly, the built-in coolant level sensors in the stock tanks are a common failure point. When they go bad, you get a false low coolant warning light on your dash, and replacing the sensor means replacing the entire tank assembly. This Wehrli kit addresses both issues. It's fabricated from aluminum for durability and a cleaner look, and it includes a high-quality, float-type sensor that's easily replaceable if it ever needs service down the road. The kit comes in a striking Brizzle Blue powder coat finish, complete with a billet aluminum cap, a sight glass for checking your coolant level, installation hardware, and an overflow hose.

This kit is a direct replacement for GM part numbers 84257137, 84214124, 84138913, and 84174037. It's a well-built solution to clean up your engine bay and eliminate a known weak point in the factory cooling system.
