Best Coolant For 5 7 Hemi: Compare 10 Options

#1 · Best Overall

1. Mopar 50/50 Premix

• Weight: 16 oz

Best for: Mopar premix for listed vehicles.

Why it ranks #1: Its MS.90032 prediluted formula is listed for several Ram applications, including Ram 1500, 2500, 4500, and 5500 model years shown.

Mopar’s 50/50 prediluted MS.90032 coolant arrives ready to pour, removing the need to measure or mix concentrate during a top-off or service. Its listed applications include several Ram models alongside Chrysler, Dodge, Jeep, and Alfa Romeo vehicles, making the application list a useful starting point for owners checking their vehicle’s specified coolant.

The premixed 50/50 liquid simplifies a refill because it is already diluted, while the MS.90032 designation identifies the formulation rather than leaving the buyer to choose a mixing ratio. Mopar lists Ram 1500, 2500, 4500, and 5500 applications among a broader vehicle range, so owners can compare the listed makes and years with their service requirements. The gallon jug suits routine automotive maintenance; verify that this exact specification matches the vehicle before filling.

Skip it if you need concentrate to set a custom dilution; Mopar Antifreeze Coolant Concentrate is the more suitable format.

Choose this Mopar jug if your service information calls for MS.90032 and the listed application covers your vehicle. Its ready-mixed format suits straightforward refills, but the Hemi designation alone does not establish coolant specification.

#2 · Best Chrysler HOAT

2. PEAK OET Gold 50/50

• Weight: 9.22 lb
• Dimensions: 7.5 x 3.4 x 11.9 in

Best for: Chrysler Gold HOAT premix.

Why it ranks #2: The prediluted gold HOAT formula is recommended for Ford and Chrysler vehicles requiring that chemistry, giving it a specific Chrysler connection.

PEAK OET Extended Life Gold is a 50/50 prediluted coolant recommended for Ford and Chrysler vehicles requiring Gold hybrid organic acid technology. That explicit application guidance makes it relevant to Hemi owners checking a Gold HOAT requirement, while its extended-life formulation and compatibility with other extended-life coolants simplify maintenance planning.

The prediluted format is ready to use, avoiding dilution calculations during a refill. PEAK says the formula is fully compatible with other extended-life antifreeze/coolants and prevents rust and corrosion across engine cooling-system components. Its recommended application specifically names Ford and Chrysler vehicles requiring Gold HOAT, a more useful fit signal than color alone. The listing’s guarantee applies when installed as part of a complete flush, so follow the stated maintenance condition and vehicle specification.

Skip it if you need coolant for a vehicle that specifies another chemistry; this product is recommended specifically for Gold HOAT applications.

This is a strong candidate when a Chrysler’s service information calls for Gold HOAT and the owner is doing a complete flush. Its stated application is specific, so do not treat it as a universal coolant for all Hemi vehicles.

#3 · Best HOAT Concentrate

3. Zerex G05 Concentrate

• Weight: 9.62 lb
• Dimensions: 7.38 x 3.83 x 12 in

Best for: G05 concentrate for Chrysler owners.

Why it ranks #3: Its G05 hybrid organic acid technology is described for newer Chrysler vehicles, while concentrate format allows a buyer to prepare the listed dilution.

Zerex G05 pairs hybrid organic acid technology with a concentrate format, offering corrosion protection and control over the final dilution. Its listing specifically describes use in newer Chrysler vehicles as well as Ford and Mercedes-Benz cars, light trucks, and heavy-duty vehicles, giving Hemi owners a relevant chemistry to investigate against their vehicle’s required specification.

The G05 hybrid organic acid technology is described as fighting rust, scale, and corrosion while protecting cooling-system metals, including aluminum; that matters when selecting coolant for a mixed-metal system. The concentrate can be mixed with clean tap or demineralized water, with listed 50/50 and 60/40 ratios tied to different temperature ranges. That flexibility supports a planned refill, but it also requires measuring and mixing, and the vehicle’s required specification should determine the choice.

Skip it if you need a premix for a quick refill; PEAK OET Extended Life Gold 50/50 is prediluted for North American vehicles requiring Gold HOAT.

Consider G05 when your vehicle’s service specification calls for this chemistry and you are comfortable mixing concentrate. The stated Chrysler coverage is relevant, but it is not a blanket confirmation for every 5.7-liter Hemi.

#4 · Best Mopar Concentrate

4. Mopar Coolant Concentrate

• Weight: 9.1 lb
• Dimensions: 7.5 x 3 x 12 in

Best for: Concentrate for custom dilution.

Why it ranks #4: Genuine Mopar concentrate is described as suitable for gas and diesel engines and all radiators, but its listing does not specify a Hemi coolant standard.

Mopar’s concentrate gives owners control over dilution instead of supplying a ready-mixed coolant, a practical distinction for planned flushes and refills. The product listing identifies it as a year/150,000-mile coolant and says it is safe for all radiators and gas or diesel engines, while the bittering agent is another clearly stated formulation detail.

Because this is concentrate, the buyer must prepare the coolant rather than pour in a pre-diluted 50/50 mix; that makes it a better workflow match when a service plan calls for mixing. Mopar describes it as suitable for all radiators and gas and diesel engines, and its description mentions coolant flushes and top-offs. Those broad statements do not replace the vehicle maker’s specification, so confirm the required coolant chemistry and dilution before use.

Skip it if you want coolant ready to pour without mixing; Mopar 68163849AB is already prediluted 50/50.

This is a sensible format for owners preparing a flush or mixing coolant to a specified ratio. Select it only when its chemistry and dilution suit the vehicle; drivers wanting a ready-to-use refill should choose a premix instead.

#5

5. Mopar 5-Year Coolant

• Weight: 9.65 lb
• Dimensions: 11.7 x 7.5 x 3.9 in

Best for: Genuine Mopar vehicle-specific coolant.

Why it ranks #5: This genuine OEM Dodge/Mopar coolant has a stated 5-year/100,000-mile description, though the listing gives less formula and vehicle-fit detail.

Genuine Mopar’s clearest differentiator is its vehicle-specific factory-fit positioning, rather than a stated universal application. The listing identifies a five-year/100,000-mile coolant and labels it a genuine Dodge/Mopar part, making it relevant to owners prioritizing an OEM-branded option while checking whether this exact coolant specification applies to their vehicle.

The factory-fit and vehicle-specific claims make this Mopar bottle a targeted option rather than a coolant with broad stated compatibility. Its five-year/100,000-mile description gives buyers a stated service horizon to compare with their maintenance plan, while the one-gallon bottle suits routine cooling-system work. The supplied details do not name a 5.7 Hemi application or explain a mixing ratio, so consult the vehicle’s service specification before using it for a refill or flush.

Skip it if you need an explicitly stated ready-to-use 50/50 mix; Mopar 68163849AB is listed as prediluted MS.90032.

This suits an owner seeking a genuine Mopar vehicle-specific coolant and willing to verify the exact application. Its OEM branding alone cannot confirm fit for every Hemi; check the service specification before purchase or use.

#6 · Longest Stated Service

6. PEAK Titanium 50/50

• Weight: 7.59 lb
• Dimensions: 8 x 3.5 x 12 in

Best for: Long-interval all-vehicle coolant.

Why it ranks #6: Its prediluted formula is presented for all vehicle cooling systems and states 15+ years or 500,000+ miles with proper maintenance.

PEAK Titanium advertises protection for over 15 years or 500,000 miles when proper cooling-system maintenance is followed, a particularly long stated service horizon. Its prediluted 50/50 format also avoids mixing, while the listing describes the yellow coolant as supporting any vehicle’s engine cooling system—claims to weigh against the vehicle’s own required specification.

The 50/50 prediluted formula simplifies a refill by eliminating dilution preparation, and PEAK’s stated service guarantee extends beyond 15 years or 500,000 miles when proper maintenance is followed. The product is described as engineered for any vehicle’s cooling system, with proprietary chemistry intended to clean component surfaces and protect them. Those broad claims offer a convenient maintenance proposition, but the guarantee’s maintenance condition matters and the vehicle maker’s coolant requirement remains the fit check.

Skip it if you want a product explicitly recommended for Chrysler Gold HOAT; PEAK OET Extended Life Gold names that application.

Consider PEAK Titanium if a ready-to-use coolant and its long stated service horizon suit your maintenance approach. Its broad all-vehicle description is not a substitute for checking the 5.7 Hemi’s specified coolant chemistry.

Listed on Amazon as: PEAK Titanium 50/50 Prediluted Antifreeze and Coolant for All Engine Cooling Systems, Long-Lasting Yellow Engine Coolant/Antifreeze for Lifetime Engine Protection in All Vehicles, 1 Gal.

#7

7. Valvoline Multi-Vehicle

• Weight: 9 lb

Best for: Multi-vehicle ready-mix users.

Why it ranks #7: The ready-to-use formula is described for all makes and models of automobiles and light trucks and as compatible with ethylene glycol coolants.

Valvoline Multi-Vehicle coolant combines a ready-to-use 50/50 mixture with Alugard Plus compatibility across ethylene glycol-based coolants in automobiles and light-duty trucks. That pairing makes it convenient for topping off without mixing, while its broad compatibility claim may help owners maintaining more than one vehicle—but the specific vehicle requirement still governs selection.

The premixed yellow formula is ready to use, avoiding a separate water-measuring step during a refill. Alugard Plus is described as compatible with all ethylene glycol-based coolants in automobiles and light-duty trucks, while the additives fight corrosion, scaling, and rust and protect metals including aluminum. The product also states protection for gaskets, hoses, and plastics. These broad claims aid routine maintenance, but they do not identify a specific Hemi coolant specification.

Skip it if you need an explicitly Chrysler-targeted Gold HOAT product; PEAK OET Extended Life Gold is recommended for vehicles requiring that formula.

This suits drivers seeking a premixed, broad-application coolant for an automobile or light-duty truck. For a 5.7 Hemi, use it only if the vehicle’s specified coolant is compatible with the product’s stated formulation.

#8

8. Zerex Dex-Cool 50/50

• Weight: 9 lb
• Dimensions: 7.38 x 3.83 x 12 in

Best for: Orange Dex-Cool premix users.

Why it ranks #8: Its ready-to-use organic acid formula is approved for vehicles requiring orange antifreeze, including some Chrysler applications, but Hemi fit is not established.

Zerex Dex-Cool arrives as a ready-to-use orange 50/50 mixture, eliminating dilution work when a vehicle calls for that coolant type. Its organic acid technology is described as resisting rust, scale, and corrosion while protecting metals including aluminum, and the listing names Chrysler among the makes with systems requiring orange antifreeze.

The premixed formula simplifies a top-off or flush because it is already diluted with deionized water at 50/50, with stated winter freeze protection to -34°F. Organic acid technology is described as guarding metals against rust, scale, and corrosion, and other additives protect gaskets, hoses, plastics, and vehicle finish. The description names Chrysler vehicles only when their cooling systems require orange antifreeze, so the specified chemistry—not the brand or engine alone—determines fit.

Skip it if you need a Chrysler Gold HOAT formula rather than orange Dex-Cool; PEAK OET Extended Life Gold is recommended for that requirement.

Choose this Zerex when the vehicle’s service information specifies orange Dex-Cool and a ready-mixed refill is useful. Chrysler is listed conditionally, so confirm the required chemistry for the particular 5.7 Hemi before filling.

#9

9. Prestone Asian Green

• Weight: 9.17 lb

Best for: Asian green premix shoppers.

Why it ranks #9: This 50/50 coolant offers Prestone CorGuard and extreme-temperature protection, but its Asian Green positioning does not establish Chrysler Hemi compatibility.

Prestone MAX Asian Green is a 50/50 premixed coolant featuring patented CorGuard technology, bringing a ready-to-pour format together with the brand’s named corrosion-protection technology. Its description also claims protection across extreme winter and summer temperatures, but its Asian Green designation makes the vehicle’s required coolant type the first consideration for Hemi owners.

The 50/50 mix removes dilution work for a refill, while CorGuard is the product’s named technology and is presented alongside claims of helping the cooling system run more efficiently and last longer. Prestone also describes extreme-temperature protection spanning deep winter freezes and summer heat, without giving a numeric range in the supplied details. This is specifically an Asian Green product, so its application should be matched to the coolant specification rather than selected by color or engine size.

Skip it if you need a Chrysler Gold HOAT coolant; PEAK OET Extended Life Gold is recommended for Ford and Chrysler vehicles requiring Gold HOAT.

This can suit a vehicle whose specification calls for Asian Green coolant and whose owner wants a premix. It is not a universal choice for Hemi engines; verify the required chemistry before using it.

#10

10. Zerex Asian Green

• Weight: 9.38 lb
• Dimensions: 7.3 x 4 x 12.05 in

Best for: Asian-vehicle green coolant users.

Why it ranks #10: Its premixed green formula is aimed at Asian makes such as Honda and Nissan, making it a poor match without confirmation of a Hemi specification.

Zerex Asian Vehicle Green comes premixed 50/50 with deionized water, so it can be used without preparing a dilution. Its phosphate additives are listed as protecting metals from corrosion, scale, and rust, while the product is explicitly aimed at vehicles whose makers specify the Asian green formula—a key boundary for Hemi shoppers.

The ready-to-use mixture removes a mixing step during maintenance, and Zerex lists protection against winter freezing to -34°F. Phosphate additives are described as safeguarding cooling-system metals, including aluminum, while other additives protect gaskets, hoses, plastics, and vehicle finish. The product description points to Asian makes that specify green coolant, such as Honda and Nissan; that makes the vehicle’s stated coolant requirement essential before considering it for a Ram Hemi.

Skip it if you need a North American Gold HOAT formula; PEAK OET Extended Life Gold 50/50 is recommended for Chrysler vehicles requiring that chemistry.

Choose this only when the vehicle specification calls for Asian Vehicle Green coolant. Its premixed format and stated component protection suit that requirement, but green color and a 5.7-liter engine alone do not establish compatibility.
