2009 Mercury Mariner Hybrid coolant level

•Do not use alcohol, methanol, brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
•Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the “FULL COLD” level. For all other vehicles which have a
coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
Add the proper mixture of coolant and water to the cooling system by
following these steps:
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
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 in vehicles originally equipped with Motorcraft Premium Gold
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%.
•Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.
•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.

Multi-point Inspection
In order to keep your vehicle running right, it is important that you have
the systems on your vehicle checked regularly. This can help identify any
potential issue before there are any problems. Ford Motor Company
suggests the following multi-point inspection to be performed at every
scheduled maintenance as the way to ensure your vehicle keeps running
right.
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 that externally mounted spare tire is properly stowed (tight)
❑Check parking brake for proper operation
❑Check safety warning lamps (brake, ABS, air bag, safety belt) for operation
❑Check cooling system fluid level and coolant strength
❑Check low voltage (underhood) 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
Multi-point inspection - Recommended at every visit
❑Check and top up fluid levels: brake, engine coolant recovery reservoir, motor/electronics reservoir and window washer.❑Inspect tires for wear and correct air pressure.
❑Check exhaust system for leaks, damage, loose parts and foreign materials.
❑Check low voltage (underhood) battery performance.
❑Check operation of horn, exterior lamps, turn signals and hazard warning lights.
❑Check radiator, coolers and heater and air conditioning hoses.
❑Inspect windshield washer spray and wiper operation.
❑Check windshield for cracks, chips and pitting.
❑Inspect for oil and fluid leaks.
❑Inspect engine air cleaner filter and elements.
❑Inspect half-shaft dust boots.
❑Check shocks, struts and other suspension components for leaks and damage.
