Your Dodge Charger runs hot, especially if you have the 5.7 or 6.4 HEMI under the hood, and the wrong coolant can quietly destroy water pump seals, gasket surfaces, and your radiator over time. The factory fill is a purple OAT (Organic Acid Technology) antifreeze that meets Mopar spec MS-90032, sometimes labeled as Mopar 10 Year/150,000 Mile coolant. Using the wrong chemistry, like a green IAT or a generic universal coolant, can cause gel, sludge, and premature corrosion in an aluminum HEMI block.
We focused on coolants that are genuinely safe for the Charger cooling system: true OAT formulas that match the purple factory fluid, plus a couple of vetted universal options that are explicitly approved for Chrysler MS-90032. Every pick below is sold on Amazon, comes as either a ready-to-use 50/50 mix or a full-strength concentrate, and is ranked on chemistry match, corrosion protection, and real-world reliability rather than marketing claims.

1. Mopar 10 Year/150,000 Mile OAT Antifreeze/Coolant Concentrate (MS-90032): Best Overall
If you want zero ambiguity, the genuine Mopar OAT coolant is the answer for any late model Dodge Charger. It is the exact purple fluid your car left the factory with, formulated to the MS-90032 specification, so it is fully compatible with the aluminum HEMI block, the V6 Pentastar, and every seal and gasket in the system. Because it is the OEM product, you never have to second guess whether a universal formula is truly safe for your engine. We treat it as the benchmark every other coolant on this list is measured against.
It ships as a concentrate, which is actually a benefit for enthusiasts because you control the mix ratio for your climate, but it does mean you must add distilled water rather than just pouring it in. That extra step, plus the fact that genuine Mopar fluid can be harder to source than big aftermarket brands, are the only real knocks against it. If you can find it and you want absolute added security, nothing beats it for a Charger.
- Exact factory-spec purple OAT chemistry for modern Charger engines
- Sold as concentrate, so you mix 50/50 with distilled water for full flexibility
- Rated for a 10 year or 150,000 mile service interval
Pros: Perfect chemistry match to the factory fill, zero compatibility guesswork; Long service life means fewer flushes over the life of the car; Backed directly by the OEM, Mopar, for Chrysler and Dodge vehicles
Cons: Concentrate must be mixed with distilled water, which is one extra step; Genuine Mopar fluid is harder to find than aftermarket brands
2. Zerex G05 Antifreeze/Coolant Concentrate: Best for Older Chargers
Zerex G05 is the right call if you have an earlier Charger that originally used the yellow HOAT coolant meeting Chrysler MS-9769. This is a low silicate HOAT formula that was a factory and fleet standard for years, and it provides excellent protection for the aluminum components and bimetal cooling passages found in older HEMI and V6 engines. Valvoline has a deep reputation here, and the fluid performs reliably across hot summers and cold winters alike.
The one thing to watch is matching it to your exact model year. Newer Chargers moved to purple OAT (MS-90032), and G05 is yellow HOAT, so this is not a universal swap for every car wearing the Charger badge. Check your owner manual or the cap on your reservoir first. If your system calls for the yellow fluid, though, G05 is a very dependable choices you can buy.
- HOAT chemistry approved for older Chrysler MS-9769 cooling systems
- Low silicate formula that protects aluminum and bimetal engines
- Trusted Valvoline brand with a long track record in fleet use
Pros: Ideal match for earlier Charger model years that used yellow HOAT; Strong corrosion protection for aluminum radiators and HEMI blocks; Widely available and easy to source on Amazon
Cons: Not the correct purple OAT for the newest Charger models; Yellow color can confuse owners expecting factory purple fluid
3. Valvoline Zerex Asian Vehicle… wait, use Zerex Original Green: Best Ready-to-Use Mix
When you just need a clean, ready-to-go OAT coolant and do not want to deal with distilled water, the Prestone Dex-Cool style 50/50 mix is a strong, convenient option. It pours straight into the reservoir, the OAT inhibitor package guards the aluminum HEMI block and the radiator against corrosion, and Prestone quality control is consistently good. For a quick top off or a complete flush and refill, the pre-diluted format saves time and removes the risk of getting the mix ratio wrong.
The honest weakness is color and mixing. This fluid is orange, not the factory purple, so it is best used after a full flush rather than splashed in on top of existing Mopar coolant, since mixing different OAT dye systems makes future diagnosis harder. As long as you do a complete drain and refill, it protects your Charger well, but treat it as a full replacement rather than a casual top off.
- Pre-mixed 50/50, so it pours straight in with no measuring
- OAT corrosion inhibitors protect aluminum, steel, and copper
- Compatible with a broad selection of OAT cooling systems
Pros: No mixing required, which makes a top off fast and clean; Strong, long lasting OAT corrosion package; Easy to find and consistent quality from Prestone
Cons: Orange OAT is not a color match for the factory purple fluid; Best used for a full flush, not mixed with leftover purple coolant
4. Prestone Command HD Heavy Duty ELC… replace with Engine Ice High Performance Coolant: Best for Track and Heat
If your Charger sees track days, autocross, or just brutal summer heat with the 6.4 HEMI, Engine Ice is a performance coolant built to pull operating temperatures down. It comes pre-mixed and ready to pour, uses a non-toxic and biodegradable base that is friendlier to handle and clean up, and is popular with enthusiasts who push their cooling systems hard. For a car that runs hot under load, the temperature reduction can be a meaningful margin of safety.
This is a specialist pick, not a factory replacement. It does not carry the Mopar MS-90032 approval, so it is not what you want if you are keeping a strict OEM service record or doing warranty work, and the performance formulation generally calls for a shorter change interval than a 10 year OAT. Use it knowing the tradeoff: lower temps and track focus in exchange for stepping outside the factory spec.
- Formulated to reduce cylinder head and operating temperatures
- Pre-mixed and ready to pour with no dilution needed
- Non-toxic, biodegradable base for easier cleanup
Pros: Helps drop temps for spirited driving and track days; Ready-to-use with no measuring; Safer, non-toxic chemistry than standard ethylene glycol
Cons: Not a Mopar MS-90032 spec match for warranty work; Performance focus means a shorter recommended service interval
5. PEAK OET Extended Life Antifreeze/Coolant for Asian and Domestic Vehicles (Purple): Best Color Match
PEAK builds its OET (Original Equipment Technology) line to match specific OEM coolant specs rather than selling one generic jug for everything, and the purple variant is aimed at vehicles that use the purple OAT factory fluid like modern Chargers. The big advantage is that the purple dye matches what is already in your system, so future top offs look right and you avoid the muddy mix of clashing colors. The extended life chemistry also keeps your flush intervals long.
The catch is that PEAK sells several OET variants by color and application, so you have to confirm you are buying the purple version intended for Chrysler purple OAT systems and not a different OET fluid. Get the right one and it is a clean, color correct, extended life choice. Grab the wrong variant and you have introduced the exact compatibility problem you were trying to avoid, so read the label carefully before you buy.
- Purple OAT dye that visually matches the factory Charger fluid
- OET line targeted to specific OEM coolant specifications
- Extended life formula for long service intervals
Pros: Color matches the factory purple, so future top offs stay consistent; Vehicle specific OET formulation rather than a one size fits all blend; Extended life chemistry reduces flush frequency
Cons: You must confirm the exact OET variant fits your Charger spec; Availability of the correct purple variant can vary
6. Genuine Mopar 10 Year/150,000 Mile Coolant 50/50 Premixed (MS-90032): Easiest OEM Refill
This is the genuine Mopar OAT coolant in pre-diluted 50/50 form, which makes it the easiest OEM refill for a Charger owner who wants the exact factory fluid without mixing anything. It is the same purple MS-90032 chemistry as our top pick, just already cut with water to the correct ratio, so a top off or a refill is as simple as pour and go. For added security plus convenience, it is hard to beat the real OEM fluid in a ready format.
Because you are buying water along with the antifreyze, you get less concentrate per jug than the full-strength version, so it is a slightly less efficient way to buy a large quantity, and like all genuine Mopar fluid it can be harder to find in stock. For a single flush or keeping a bottle in the trunk for emergencies, though, this premixed OEM option is the no-fuss choice.
- Genuine Mopar fluid already diluted to a ready 50/50 mix
- Exact MS-90032 purple OAT chemistry for the Charger
- Pour straight in for top offs with no distilled water needed
Pros: OEM chemistry and convenience of a pre-mixed bottle; Perfect color and spec match for the factory system; No measuring or distilled water required
Cons: Pre-mixed means you carry water weight, so value per jug is lower; Can be harder to source than aftermarket pre-mix
7. Valvoline Multi-Vehicle 50/50 Prediluted Antifreeze/Coolant: Best Universal Backup
A multi-vehicle universal coolant earns a spot here as the smart backup to keep in your garage or trunk. The Valvoline Multi-Vehicle 50/50 is engineered to be compatible across coolant colors and major OEM specifications, including Chrysler systems, so if your Charger is low and you need to get home, you can top it off without worrying about a chemistry clash. It is pre-mixed, so there is no measuring, and Valvoline backs it with a solid corrosion inhibitor package that protects the aluminum in the HEMI cooling system.
The honest tradeoff is that any universal coolant is a compromise compared to a coolant dedicated to one spec. The inhibitors are tuned to play nice with everything rather than to be the absolute best match for purple OAT, so for a meticulous owner keeping a strict OEM record, a dedicated MS-90032 fluid is the better long term fill. As an emergency top off or a general purpose option, though, this is the universal bottle worth owning.
- Compatible with all colors and major OEM coolant specs
- Pre-mixed 50/50 for fast, mess free top offs
- Phosphate and silicate balanced for aluminum protection
Pros: Broad compatibility makes it a safe emergency top off; Ready-to-use with no dilution; Reliable Valvoline corrosion protection
Cons: A universal blend is a compromise versus a dedicated OAT fluid; Not the ideal long term fill for a strict OEM service record
Frequently Asked Questions
What kind of coolant does a Dodge Charger use?
Most modern Dodge Chargers use a purple OAT (Organic Acid Technology) antifreeze that meets Mopar specification MS-90032, often sold as Mopar 10 Year/150,000 Mile coolant. Earlier Charger model years used a yellow HOAT coolant meeting Chrysler MS-9769. The fastest way to confirm yours is to check the color of the fluid in the overflow reservoir and look at your owner manual. Purple means OAT, yellow means HOAT, and you should match whichever your system was designed for rather than guessing.
Can I use any universal or green coolant in my Charger?
You should avoid old style green IAT coolant in a Charger, because that chemistry is not designed for the long service intervals and aluminum components in a modern HEMI or Pentastar engine, and it can cause corrosion and gasket issues. A quality universal coolant that is explicitly approved for Chrysler MS-90032 or MS-9769 is acceptable as an emergency top off, but for the best long term protection you want a coolant that matches your factory spec exactly. When in doubt, stick with the OAT chemistry the car came with.
Do I need to mix concentrate coolant with water?
Yes. A concentrate coolant must be diluted, normally to a 50/50 ratio with distilled water, before it goes into your Charger. Never use tap water, because the minerals in it cause scale and corrosion inside the cooling system. Always use distilled water. If you do not want to mix anything, buy a coolant labeled as pre-mixed or 50/50, which is already diluted and ready to pour straight into the reservoir. Both forms protect the engine equally well when used correctly.
How often should I change the coolant in a Dodge Charger?
The factory OAT coolant in a modern Charger is rated for roughly 10 years or 150,000 miles for the first change, then on a shorter interval after that, but always follow the schedule in your specific owner manual. Performance or non-OAT coolants usually call for more frequent changes. Beyond the mileage, inspect the fluid for a rusty color, floating debris, or a low level, since any of those mean it is time for a flush regardless of how many miles have passed.
Is it safe to mix different colors of coolant?
It is best not to mix coolant colors. Different colors usually signal different inhibitor chemistries, and combining them can reduce corrosion protection or, in the worst case, cause gel and sludge that clogs the radiator and heater core. If your Charger has purple OAT, top off with purple OAT. If you are switching brands or types, do a complete flush and refill so the entire system holds one consistent chemistry rather than a blend of two. That keeps the cooling system clean and your future diagnostics simple.
Our Verdict
For nearly every Dodge Charger owner, the genuine Mopar 10 Year/150,000 Mile OAT concentrate is the best coolant you can buy, because it is the exact MS-90032 purple chemistry your engine was engineered around, with no compatibility guesswork and a very long service life. If you have an earlier Charger that runs the yellow HOAT fluid, our runner up, Zerex G05, is the dependable, widely available match that protects the aluminum HEMI cooling system beautifully. Match the coolant to your factory spec, use distilled water if you go with a concentrate, and your Charger will run cool and corrosion free for years.
