Check and Add Coolant

The Dodge Charger LX (2006–2010) uses a closed cooling system designed to maintain stable engine temperatures in all conditions. The correct coolant type is Mopar HOAT (Hybrid Organic Acid Technology) antifreeze/coolant, dyed orange or pink depending on production year. Keeping the coolant at the proper level prevents overheating and engine damage.

What You Need

• Mopar HOAT coolant (orange/pink) or an approved equivalent
• Distilled water (if mixing concentrate)
• Funnel with a small spout
• Clean rag
• Gloves and eye protection

Locate the Coolant Reservoir

• Open the hood and locate the translucent coolant reservoir (also called the overflow tank) on the passenger side of the engine bay.
• The cap is labeled Engine Coolant.
• The tank has COLD FILL MIN and FULL marks molded into the side.

How to Check Coolant Level

1. Always check coolant when the engine is cold to avoid burns.
2. Look at the side of the translucent tank — the fluid should be between COLD FILL MIN and FULL.
3. If the level is low, proceed to topping up.

How to Add Coolant

1. Ensure the engine is cool before opening the cap.
2. Slowly remove the reservoir cap to release pressure.
3. Add pre-mixed 50/50 Mopar HOAT coolant and distilled water, or use Mopar premix.
4. Fill until the fluid reaches the FULL line.
5. Reinstall the cap tightly.

Maintenance Notes

• Coolant change interval: approximately every 5 years or 100,000 miles (160,000 km).
• Never mix HOAT with OAT or generic green coolant — it can reduce corrosion protection.
• If coolant is dark, rusty, or contaminated, a full flush and refill is recommended.

Safety Tips

• Never open the reservoir cap on a hot engine — scalding fluid under pressure can spray out.
• Dispose of used coolant safely — it is toxic to animals and the environment.
• Check hoses and clamps for leaks while inspecting coolant levels.
