Wehrli 20-24 Duramax L5P Auxiliary Coolant Tank Kit - Chevy Orange

Wehrli Custom Fabrication is known for making well-built parts for Duramax trucks. If you're looking to clean up the engine bay on your 2020-2025 L5P Duramax Silverado or Sierra HD, this auxiliary coolant tank kit is a solid option. It replaces the factory clear plastic reservoir for the fuel cooler system with a custom-fabricated aluminum tank that's powder-coated in Chevy Orange.

This kit includes a black anodized billet aluminum cap and all the necessary mounting hardware. It's designed to mount in the OEM location and uses the stock mounting points, so installation is straightforward with basic hand tools. The aluminum construction and custom powder coating give your engine bay a much cleaner, more finished look compared to the factory plastic tank. It also includes a pre-formed hose and an overflow flow fitting.
