Coolant Flush for 2020 Chrysler Voyager LX - Type and Interval?

Performing a coolant flush at the recommended intervals is essential for maintaining your 2020 Chrysler Voyager LX's engine health and preventing overheating.

Coolant Type and Interval:

• Your 2020 Chrysler Voyager LX requires OAT (Organic Acid Technology) coolant, specifically Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula (color typically purple/pink). It's crucial to use this specific type and never mix it with other coolant types (like HOAT or IAT), as this can lead to gel formation, corrosion, and severe engine damage.
• The general recommended service interval for this OAT coolant is 10 years or 150,000 miles, whichever comes first. At 60,000 miles, you are well within the factory specified interval, but if you're experiencing issues like frequent cooling fan operation or notice the coolant looks discolored, an earlier flush could be considered.

DIY Considerations:

1. Safety First: Ensure the engine is completely cool before starting. Wear appropriate safety gear (gloves, eye protection).
2. Drain: Locate the radiator drain cock (petcock) at the bottom of the radiator and the engine block drain plugs (if accessible and recommended by the manual). Place a large drain pan underneath. Open the radiator cap to help it drain.
3. Flush (Optional but Recommended): Once drained, close the petcock and fill with distilled water. Run the engine with the heater on high until it reaches operating temperature, then drain again. Repeat until the drained water runs clear. This removes old coolant and contaminants.
4. Refill: Close all drains. Slowly fill the system with the correct Mopar OAT coolant (50/50 mix with distilled water, or pre-mixed). Start the engine with the heater on high, and allow it to warm up, adding more coolant as the level drops and air bubbles escape. Squeeze radiator hoses to help burp air.
5. Check for Leaks: Monitor the coolant level over the next few days and check for any leaks.

When to See a Shop:

• If you're experiencing frequent overheating, even after checking coolant levels. This could indicate a failing water pump, thermostat, or radiator.
• If you're uncomfortable with the process, especially with proper disposal of old coolant.
• If you receive an OBD-II code related to the cooling system, such as P0117 (Engine Coolant Temperature Sensor Low) or P0118 (Engine Coolant Temperature Sensor High), which might indicate sensor issues or actual overheating.
