10. If necessary, add a50/50 mixtureof coolant and distilled water to
the coolant reservoir until the coolant level is at the “cold fill range” as
listed on the reservoir.
After any coolant has been added, check the coolant concentration (refer
toChecking coolantin theOwner’s Guide).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 enough 50/50 concentration of coolant and distilled water
to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of coolant per month,
have your dealer check the cooling system. Your cooling system may
have a leak. Operating an engine with a low level of coolant can result in
engine overheating and possible engine damage.
ENGINE SPARK PLUG INTERVAL
To keep your high performance engine operating at peak performance,
the spark plug service interval is every 45,000 miles (72,000 km).
Reference the Motorcraft Part Numbers chart for the specific spark plug
application.

unleaded gasoline with octane rating
of 93 or higher for optimal performance of this vehicle. Recommended
fuel is an important part of the proper maintenance and optimal
performance of this vehicle. The use of gasoline with octane ratings of 91
or lower can lead to severe mechanical damage to your vehicle, may
