Mishimoto Aluminum Expansion Tank 2015+ Charger Challenger

The Mishimoto Aluminum Expansion Tank 2015+ Charger Challenger serves as the engine coolant expansion tank for 2015+ Dodge Charger and Challenger models, including 6.4L and 6.2L Hellcat variants, providing a durable, corrosion‑resistant aluminum alternative intended to enhance long‑term reliability under demanding use.

This expansion tank is engineered to integrate with the factory cooling system of the specified 2015+ Charger and Challenger platforms. Built from aluminum, the tank resists deterioration common to polymer reservoirs and maintains structural integrity when exposed to heat cycles and road‑side conditions.

Why this matters

• Aluminum construction — provides corrosion resistance and dimensional stability, which supports consistent coolant containment and reduces the risk of failure from material fatigue.
• Model‑specific fitment — designed for 2015+ 6.4L Charger and Challenger and 6.2L Hellcat variants to ensure straightforward installation and proper hose routing without modification.
• Mishimoto engineering — developed by a specialist motorsports supplier to meet the expectations of performance‑oriented vehicles while offering a more robust alternative to the original component.

Performance and serviceability

The part focuses on functional reliability: it preserves coolant containment and system pressure interfaces in a package that withstands repeated thermal cycles. The design approach emphasizes durable materials and accurate vehicle compatibility to minimize installation time and maintain engine cooling performance.

Brand note

Mishimoto is identified with aftermarket cooling components and engineered replacements tailored to performance vehicles; this expansion tank reflects that application‑driven design philosophy for late‑model Charger and Challenger platforms.
