cooling LINCOLN MKZ 2011 User Guide

4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture, to
within the COLD FILL RANGE or the FULL COLD level on the reservoir.
If you removed the radiator cap in an overflow system, fill the radiator
until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration (refer
toChecking engine coolant). 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 engine 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 engine coolant per
month, have your authorized dealer check the engine 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.
Recycled engine coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
toMaintenance product specifications and capacitiesin this chapter.
Fill your engine coolant reservoir as outlined inAdding engine coolant
in this section.
Severe climates
If you drive in extremely cold climates (less than –34°F [–36°C]):
•It may be necessary to increase the coolant concentration
above 50%.

•NEVER increase the coolant concentration above 60%.
•A coolant concentration of 60% will provide freeze point
protection down to -62°F [-52°C]. Increased engine coolant
concentrations above 60% will decrease the overheat
protection characteristics of the engine coolant and may cause
engine damage.
•If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle will provide
adequate freeze protection at the temperatures in which you
drive in the winter months.
If you drive in extremely hot climates:
•It is still necessary to maintain the coolant concentration
above 40%.
•NEVER decrease the coolant concentration below 40%.
•A coolant concentration of 40% will provide freeze point
protection down to -12°F [-24°C]. Decreased engine coolant
concentrations below 40% will decrease the corrosion/freeze
protection characteristics of the engine coolant and may cause
engine damage.
•If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle will provide
adequate protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature gauge will move to the H (hot) area.
•The
symbol will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.

•Cover interior trim to prevent fading.
•Keep all rubber parts free from oil and solvents.
Engine
•The engine oil and filter should be changed prior to storage, as used
engine oil contain contaminates that may cause engine damage.
•Start the engine every 15 days. Run at fast idle until it reaches normal
operating temperature.
•With your foot on the brake, shift through all the gears while the
engine is running.
Fuel system
•Fill the fuel tank with high-quality fuel until the first automatic shutoff
of the fuel pump nozzle.
Note:During extended periods of vehicle storage (30 days or more),
fuel may deteriorate due to oxidation. Add MotorcraftGas Stabilizer or
equivalent meeting Ford material specification ESE-M99C112-A to the
vehicle fuel system whenever actual or expected storage periods exceed
30 days. Follow the instructions on the additive label. The vehicle should
then be operated at idle speed to circulate the additive throughout the
fuel system.
Cooling system
•Protect against freezing temperatures.
•When removing vehicle from storage, check coolant fluid level.
Confirm there are no cooling system leaks, and fluid is at the
recommended level.
Battery
•Check and recharge as necessary. Keep connections clean.
•If storing your vehicle for more than 30 days without recharging the
battery, it may be advisable to disconnect the battery cables to ensure
battery charge is maintained for quick starting.
Note:If battery cables are disconnected, it will be necessary to reset
memory features.
Brakes
•Make sure brakes and parking brake are fully released.
Tires
•Maintain recommended air pressure.

Multi-point inspection
In order to keep your vehicle running right, it is important to have the
systems on your vehicle checked regularly. This can help identify
potential issues and prevent major problems. Ford Motor Company
recommends the following multi-point inspection be performed at every
scheduled maintenance interval to help ensure your vehicle keeps
running great.
Engine coolant change interval
❑6 years or 100,000 miles (160,000 km) - change engine coolant (whichever comes first)❑After initial change - change engine coolant every 3 years or 50,000 miles (80,000 km)
Check every month
❑Check function of all interior and exterior lights❑Check tires for wear and correct air pressure, including spare tire
❑Check windshield washer fluid level
❑Check engine oil level
Check every six months
❑Check lap/shoulder belts and seat latches for wear and function❑Check parking brake for proper operation
❑Check safety warning lamps (brake, ABS, airbag, safety belt) for operation
❑Check cooling system fluid level and coolant strength
❑Check battery connections and clean if necessary
❑Check washer spray, wiper operation and clean all wiper blades (replace as necessary)
❑Check and lubricate all hinges, latches and outside locks. Inspect for correct operation
❑Check and lubricate door rubber weatherstrips. Inspect for excessive wear
❑Check and clean body and door drain holes. Inspect for clogs and obstructions
