Maintenance and Specifications Engine coolant refill procedure-4.6L V8 engine The following procedure should be used when refilling the cooling system of a 4.6L V8 engine after it has been drained or become extremely low. 1. Remove the pressure relief cap from the engine coolant reservoir as previously outlined. 2. Slowly add a 50/50 mixture of engine coolant and distilled water to the engine coolant reservoir until the coolant level is at the "cold fill level" as listed on the reservoir. 3. Reinstall the pressure relief cap. 4. Start and idle the engine until the upper radiator hose is warm (this indicates the thermostat is open and coolant is flowing through the entire system). 5. Shut the engine off and let it cool. 6. Remove the pressure relief cap from the engine coolant reservoir as previously outlined. 7. Add a 50/50 mixture of engine coolant and distilled water to the engine coolant reservoir until the coolant level is at the "cold fill level" as listed on the reservoir. 8. Reinstall the pressure relief cap. 9. Check the coolant level in the reservoir before you drive your vehicle the next few times (with the engine cool). 10. If necessary, add a 50/50 mixture of engine coolant and distilled water to the engine coolant reservoir until the coolant level is at the "cold fill level" as listed on the reservoir. After any coolant has been added, check the coolant concentration see Checking Engine Coolant section). If the concentration is not 50/50 (protection to -34° F/-36° C), drain some coolant and adjust the concentration. It may take several drains and additions to obtain a 50/50 coolant concentration. Whenever coolant has been added, the coolant level in the coolant reservoir should be checked the next few times you drive the vehicle. If necessary, add 211
