Product Description

The aFe POWER 46-51001 BladeRunner GT Series Engine Coolant Expansion Tank is a direct bolt-on upgrade for 2015-2023 Dodge Challenger and Charger models equipped with the 6.4L SRT 392 or 6.2L Hellcat HEMI engine. It replaces the factory plastic coolant reservoir - a component prone to yellowing, cracking, and brittleness as it ages - with a fully TIG-welded 1/8" thick aluminum tank that provides 15% more coolant capacity and significantly greater durability under high operating temperatures.

Billet aluminum fittings eliminate the plastic connection points that are often the first to fail on the stock tank, and a stainless-steel-fitted sight tube allows quick fluid level checks and top-offs without removing the cap. The brushed aluminum finish and laser-etched aFe POWER logo clean up the engine bay dramatically compared to the stock yellowed plastic. Installation is a straightforward bolt-on using factory connections and the factory expansion tank cap - no modifications required. For 6.2L Hellcat models, also consider the companion supercharger intercooler coolant tank (PN 46-51002) for a complete cooling system refresh.
