Dodge and Chrysler have carefully crafted the 2015-2023 6.4L Dodge Charger, Challenger, and their 6.2L Hellcat variants with imposing exteriors that live up to their namesakes. One would expect the same attention to detail under the hood and, for the most part, it all adds up - except one part: the factory expansion tank. Sticking out like a sore thumb, the dull yellow reservoir for your Mopar's coolant ends the envy brought on by the exterior. Looks aside, these plastic tanks are notorious for degrading and leaking over time. ---- We here at Mishimoto are determined to inject some style into the engine bay of your Mopar with the Mishimoto 2015-2023 Dodge Charger/Challenger and Hellcat Aluminum Expansion Tank. We have eliminated the dingy beige plastic of the stock tank and replaced it with TIG-welded aluminum, exponentially improving the expansion tank's aesthetics and durability. We also ditched the need for a sight glass or tube by incorporating a cold-fill line within the internal baffling, keeping the sleek exterior design of our tank unblemished. ---- The Mishimoto 2015-2023 Dodge Charger/Challenger 6.4L/6.2L Hellcat Expansion Tank is available in a micro-wrinkle black or natural finish. The natural finish is easy to make match any color scheme through powder coating or hydro dipping. Our expansion tank includes the Mishimoto Lifetime Warranty, which ensures you'll never again have to see the eyesore that is the stock plastic expansion tank.

  • 100-percent aluminum, TIG-welded construction for maximum durability after repeated temperature transitions
  • Available natural finish makes customization easy through powder coating, anodizing, or hydro dipping
  • Cold fill tab incorporated into internal baffling to retain sleek exterior design

Good to know

Questions, answered straight.

If it is not here, call or text the counter. Real people, real answers.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
