4. Setup and Initial Fill
- Ensure Engine is Cool: Never open the cooling system when the engine is hot. Allow the engine to cool completely.
- Locate Radiator Cap and Reservoir: Identify your vehicle's radiator cap and coolant reservoir.
- Drain System (if performing a full flush): Completely drain the cooling system by opening the valve at the bottom of the radiator. Consult your owner's manual for specific draining procedures.
- Flush System (if necessary): To remove sediment or old coolant, flush the radiator with water until clear. Run the engine with the heater on, then drain again. Repeat until the system is clean.
- Refill System: Close the drain valve. Fill the cooling system with Mopar 50/50 Premixed Antifreeze/Coolant. Do not add water.
- Bleed Air: Run the engine with the heater on high to circulate the coolant and remove any air pockets. Top off the reservoir as needed.

5. Operating and Maintenance
This Mopar coolant is prediluted 50/50, meaning it is ready to use directly from the bottle. No additional water is required. Regularly check your coolant level in the reservoir. The fluid level should be between the 'MIN' and 'MAX' marks when the engine is cool.
Top-Off Instructions:
- Ensure the engine is cool.
- Remove the coolant reservoir cap.
- Add Mopar 50/50 Premixed Antifreeze/Coolant directly to the reservoir until the fluid level reaches the 'MAX' mark.
- Replace the cap securely.
The coolant is designed for 10 years or 150,000 miles. However, regular inspection of the coolant condition and level is recommended as part of routine vehicle maintenance.

6. Troubleshooting
- Low Coolant Level: If the coolant level is consistently low, inspect the cooling system for leaks. Address any leaks promptly.
- Engine Overheating: If the engine overheats, pull over safely and allow the engine to cool. Check the coolant level and inspect for visible leaks or damage to hoses and radiator. Consult a qualified mechanic if the issue persists.
- Coolant Color Change: A significant change in coolant color (e.g., rusty appearance) may indicate contamination or corrosion. A full system flush and refill may be necessary.
