Wehrli Custom Fabrication WCF100212-FB OEM Placement Coolant Tank Kit Flat Black

The Wehrli Custom Fabrication WCF100212-FB is a fabricated aluminum coolant tank kit finished in a durable Flat Black powder coat. Designed as a direct OEM-placement replacement for the factory plastic coolant reservoir (degas bottle), this kit mounts in the factory location using the existing OEM mounting points — no drilling, cutting, or modifications required.

Built from high-quality fabricated aluminum, this coolant tank is a significant upgrade over the failure-prone, yellowing factory plastic reservoir. The billet aluminum construction provides superior durability and heat resistance, while the included coolant level sight glass allows for fast, convenient fluid level checks at a glance. The CNC-machined black anodized billet aluminum cap delivers a premium finished look and a secure, leak-free seal.
