## Cooling System Leak Testing L81

### Coolant Replacement

Important: The vehicle must be level when filling the cooling system.

1. Slowly add a mixture of 50/50 DEX-COOL® antifreeze and clean water to the coolant surge tank until the level reaches the Cold line (surge tank seam).

Specification
The cooling system volume, including the heater core, is 7.4 L (7.8 qt).

2. Start the engine and check for leaks.
3. Run the engine until the thermostat has opened.

3.1. | Use a scan tool to verify the ECT is between 87-90°C (188-196°F).

3.2. | Cycle the RPM from idle to 3000 in 30 seconds intervals to aid in bleeding off the cooling system.

3.3. | Add coolant as necessary to bring the level up to the coolant surge tank Cold line (surge tank seam).

4. Install the coolant surge tank coolant cap.

## Cooling System Leak Testing L61
