Wehrli Custom Fabrication WCF100542-SGS OEM Placement Fabricated Aluminum Coolant Tank Kit - Sparkle Granny Smith

The Wehrli Custom Fabrication WCF100542-SGS is a premium fabricated aluminum coolant tank kit finished in Sparkle Granny Smith powder coat, designed to mount in the OEM coolant tank location. This kit replaces the aging, yellowed stock plastic coolant reservoir with a durable, custom-crafted aluminum tank that improves both engine bay appearance and long-term reliability.

Built entirely in the USA by WCFab, this direct-fit upgrade uses the factory mounting points and installs with basic hand tools — no additional modifications required. A built-in billet aluminum coolant level sight glass makes checking coolant levels quick and easy without removing the cap. The kit also retains the factory low coolant level sensor for maintained safety monitoring.

• Fabricated aluminum coolant tank with Sparkle Granny Smith powder coat finish
