SKU: WCF100268-GB
2020-2025 Chevrolet Silverado or GMC Sierra HD with the 6.6L L5P Duramax diesel engine using the Wehrli Custom Fabrication OEM Placement Coolant Tank Kit in Gloss Black (Part Number: WCF100268-GB). This kit delivers a direct replacement for the factory plastic reservoir, mounted precisely in the OEM location on the driver's side firewall. Built from laser-cut, CNC-bent, and TIG-welded aluminum, it withstands the rigors of high-performance diesel operation far better than stock components, preventing common failures like sensor issues or tank cracking from heat, pressure, or contamination. Truck owners choose this kit for its straightforward installation no modifications needed on unmodified vehicles and its clean integration that enhances the engine bay's appearance while maintaining full functionality.
Key Performance Advantages
This aluminum tank addresses the limitations of the OEM plastic design head-on. The factory unit often develops non-serviceable sensor problems, leading to costly full replacements, and it yellows or builds up grime over time. In contrast, the WCF100268-GB features a serviceable low coolant level sensor that threads in easily and can be replaced independently, ensuring long-term reliability. The durable aluminum construction resists damage from head gasket issues or extreme temperatures, keeping your cooling system sealed and efficient. Paired with OEM-style hoses and fittings, it supports consistent coolant flow and pressure management, making it the reliable pick for daily drivers, heavy haulers, or tuned L5P trucks. Drivers report fewer leaks and easier maintenance, turning a routine vulnerability into a strength.
Vehicle Fitment Details
Notes: Fits first-generation L5P platform post-2020 body redesign with driver's side firewall tank location. Not compatible with 2017-2019 L5P models or custom twin-turbo setups requiring battery relocation.

Coolant reservoirs, also called expansion tanks or overflow bottles, maintain a pressurized coolant supply that the radiator draws from as the cooling system cools down after engine-off.

Universal inline overflow tanks made from polished aluminum or anodized billet are popular on custom engine bays where the stock location has been eliminated. Direct-fit OEM-style replacement tanks restore coolant system function on high-mileage vehicles where the factory tank has cracked or the cap seat has deteriorated.How do I know if my coolant reser...
