Coolant Expansion Tank Relocation Kit

Upgrade your engine bay with the RIPP Expansion tank, designed for Dodge Charger, Challenger, and Chrysler 300 models with a HEMI V8 or Pentastar V6 engine.

Not compatible with the factory air box.

This upgrade replaces the factory plastic coolant tank, notorious for its brown stains, cracking, and leaking issues. Our billet aluminum tank is finished in a satin black powder coat. It complements your engine bay's style while eliminating the OEM tank's visual eyesore. An integrated fluid sight provides a clear level indicator to inspect fluid condition without opening the cap. 

The tank also provides additional clearance for upgraded air intake systems, making it a great companion for cold air intakes and superchargers.

The kit includes all necessary hardware, including a RIPP pressure cap, relocation bracket, hardware, coolant feed, return lines, hoses designed to integrate seamlessly, and Fittings with serviceable Viton O-ring seals. This is a complete Bolt-on kit.

Please note: This expansion tank is included with the RIPP Dodge Charger/Challenger 5.7L Supercharger Kit

Pro Tips:

Engine Cooling Service: We recommend flushing the cooling system every 45,000 miles or every 4 years. This helps remove any accumulated debris, contaminants, and old coolant, ensuring the proper functioning of the cooling system. Your coolant system service should also check coolant expansion tanks, hoses, and fittings. 

Coolant Mixture: The coolant-to-water mixture in an engine's cooling system regulates the engine's operating temperature. The mixture typically consists of coolant and water. The standard recommended mixture is a 50:50 mix. However, adjusting the ratio as deemed necessary in race applications or hot environments is common. A higher water content enhances the thermal conductivity of the mixture, improving its ability to transfer heat away from the engine components. This can benefit a race application where the engine is subjected to high loads and temperatures. Always consult a professional, as every vehicle will have its own variables.
