Best Coolant For Dodge Charger – Extended Life Coolant Options

by

Your Charger’s cooling system protects the engine from thermal stress during demanding driving conditions. Using the correct coolant formulation prevents corrosion in aluminum components. Finding the best coolant for dodge charger is essential for keeping your HEMI or V6 running strong for years.

Coolant isn’t just about freezing protection. It lubricates the water pump and prevents scale buildup. The wrong coolant can damage your heater core or radiator.

Best Coolant For Dodge Charger

Dodge recommends using OAT (Organic Acid Technology) coolant for all modern Chargers. This type of coolant is typically orange or purple. It lasts longer than traditional green coolant and protects aluminum parts better.

For 2011 and newer Chargers, you need Mopar OAT coolant or an equivalent. Older models (2006-2010) may use HOAT (Hybrid OAT) coolant. Always check your owner’s manual first.

Top Coolant Options For Your Charger

Here are the best coolants available for Dodge Charger models. Each one meets factory specifications.

  • Mopar 10 Year/150,000 Mile Coolant – Factory fill. Orange color. Best for 2013+ models.
  • Mopar Purple OAT Coolant – Used in 2018+ Chargers with the 5.7L and 6.4L HEMI.
  • Prestone All Vehicles – Works for older Chargers. Yellow color. Compatible with all types.
  • Zerex G-05 – Good for 2006-2010 Chargers. HOAT formula. Yellow-green color.
  • Peak OAT Concentrate – Meets Mopar MS-12106 spec. Affordable alternative.

Why Coolant Type Matters For Your Charger

Dodge Chargers have aluminum cylinder heads and radiators. Using the wrong coolant causes electrolysis. This eats away at aluminum surfaces from the inside.

Traditional green coolant (IAT) contains silicates. These can gel up and clog your heater core. OAT coolant is silicate-free and phosphate-free. It provides better protection for modern engines.

If you mix coolant types, you risk creating sludge. This reduces cooling efficiency and can cause overheating. Stick to one type throughout the system.

How To Choose The Right Coolant For Your Charger

Selecting the best coolant for dodge charger depends on your model year and engine. Follow these steps to get it right.

  1. Check your owner’s manual for the coolant specification number.
  2. Look at the coolant color in your reservoir. Orange or purple means OAT.
  3. Confirm the freeze point rating for your climate. -34°F is standard.
  4. Decide between concentrate or pre-diluted. Pre-diluted is easier but costs more.
  5. Buy from a reputable brand. Avoid no-name coolants from discount stores.

Coolant Specifications By Charger Model Year

Different years require different coolants. Here is a quick reference guide.

  • 2006-2010 Charger – HOAT coolant (Zerex G-05 or Mopar HOAT). Pink or yellow-green.
  • 2011-2017 Charger – OAT coolant (Mopar Orange). Meets MS-12106 spec.
  • 2018-2024 Charger – OAT coolant (Mopar Purple). Meets MS-90032 spec.
  • HEMI 5.7L, 6.4L, 6.2L Supercharged – Always use OAT. Purple for 2018+.
  • 3.6L Pentastar V6 – Same as HEMI for your model year. Orange or purple.

Step-By-Step Coolant Change Guide

Changing your coolant is a straightforward job. You can do it in your driveway with basic tools. Here is how to do it properly.

Tools And Materials Needed

  • 2 gallons of the correct coolant concentrate
  • 1 gallon of distilled water
  • Funnel
  • Drain pan (at least 2 gallons capacity)
  • Socket set (10mm and 13mm)
  • Pliers for hose clamps
  • Safety glasses and gloves

Draining The Old Coolant

  1. Park on level ground. Let the engine cool completely. Coolant is hot and pressurized.
  2. Place the drain pan under the radiator drain plug. It is on the bottom passenger side.
  3. Open the radiator cap to allow air in. This helps the coolant drain faster.
  4. Turn the drain plug counterclockwise. Use a flathead screwdriver if needed.
  5. Let all coolant drain out. Dispose of it at a recycling center. Never pour it down the drain.

Flushing The System

Flushing removes old coolant residue and debris. It is important for a complete change.

  1. Close the radiator drain plug. Tighten it by hand plus a quarter turn.
  2. Fill the radiator with distilled water. Use about 2 gallons.
  3. Replace the radiator cap. Start the engine and let it run for 10 minutes.
  4. Turn on the heater to full hot. This circulates water through the heater core.
  5. Turn off the engine. Let it cool down again.
  6. Drain the water the same way you drained the coolant.
  7. Repeat the flush if the water comes out dirty. Do it until it runs clear.

Adding New Coolant

  1. Close the drain plug securely.
  2. Mix the coolant concentrate with distilled water. Use a 50/50 ratio for most climates.
  3. Pour the mixture into the radiator using a funnel. Fill until it reaches the top.
  4. Fill the overflow reservoir to the “Full Cold” line.
  5. Replace the radiator cap. Start the engine and let it idle.
  6. Watch the temperature gauge. The thermostat will open and coolant level will drop.
  7. Add more coolant mixture to the radiator until it stays full.
  8. Check for leaks around the drain plug and hoses.

Common Coolant Problems In Dodge Chargers

Even with the best coolant for dodge charger, issues can arise. Here are problems to watch for.

Coolant Leaks

Leaks often come from the water pump or radiator hoses. The water pump on HEMI engines is a known weak point. Look for pink or orange residue near the front of the engine.

Check the radiator end tanks for cracks. Plastic tanks can fail after 5-7 years. If you see coolant on the ground, fix it immediately.

Overheating

Overheating can happen if the coolant is old or low. The thermostat may stick closed. The radiator fan might fail. Always check coolant level first.

If the temperature gauge goes past halfway, pull over safely. Do not open the radiator cap until the engine cools. Serious burns can occur.

Coolant Color Changes

Coolant should stay its original color. If it turns brown or rusty, you have contamination. This means internal corrosion or mixing with wrong coolant.

Milky coolant indicates oil in the system. This is a sign of a blown head gasket. Get it checked by a mechanic right away.

When To Change Your Charger’s Coolant

Dodge recommends changing coolant every 10 years or 150,000 miles for OAT types. But real-world conditions vary. Change it sooner if you drive in extreme heat or cold.

Check your coolant every oil change. Look at the color and level. Top off with the same type if needed. Never add water alone for extended periods.

For older Chargers with HOAT coolant, change every 5 years or 60,000 miles. This prevents silicate deposits from forming.

Signs You Need A Coolant Change

  • Coolant looks rusty or muddy
  • Sweet smell from the engine bay
  • Engine runs hotter than normal
  • Heater blows cold air
  • Coolant level drops frequently

Mixing Coolants: What You Need To Know

Mixing different coolant types can cause problems. OAT and HOAT coolants are not always compatible. Adding green coolant to orange coolant creates a gel-like substance.

If you are unsure what is in your system, flush it completely. Then use the correct coolant for your Charger. This prevents damage and keeps your warranty valid.

Some coolants claim to be “universal” or “all makes all models.” These are usually yellow or clear. They work in a pinch but are not ideal for long-term use. Stick with Mopar or equivalent.

Coolant Additives: Do You Need Them?

Aftermarket coolant additives are generally not needed. Modern coolants already contain corrosion inhibitors and lubricants. Adding extra chemicals can upset the balance.

Some additives claim to stop leaks or improve cooling. They often clog the heater core or radiator. Use them only as a temporary fix. Replace the faulty part instead.

If you have a high-performance Charger, consider a water wetter additive. It reduces surface tension and improves heat transfer. But only use it with the correct coolant base.

Coolant For Supercharged Chargers (Hellcat, Redeye)

Supercharged Chargers generate more heat than standard models. The 6.2L HEMI needs excellent cooling. Use Mopar Purple OAT coolant for 2018+ models.

These cars have an additional intercooler system. It uses a separate coolant loop. Check both the engine coolant and intercooler coolant levels regularly.

For track use, consider a higher concentration of coolant. A 70/30 mix (coolant/water) raises the boiling point. But it reduces freeze protection. Adjust based on your climate.

Coolant And Warranty Considerations

Using the wrong coolant can void your warranty. Dodge requires Mopar-approved coolant for warranty claims. If you use an aftermarket brand, keep the receipt showing it meets the spec.

Document your coolant changes. Write down the date, mileage, and coolant type used. This helps if you have a cooling system issue later.

Some dealerships check coolant type during service. If they find non-Mopar coolant, they may deny coverage. Play it safe and use the factory stuff.
