cooling Mercury Mountaineer 2010 s User Guide

What you should know about fail-safe cooling
(4.6L V8 engine only)
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.
Fail-safe cooling and engine oil overheat mode (4.6L V8 only)
If the engine coolant and/or engine oil overheat, the vehicle’s fail-safe
modes will reduce engine power to limit engine damage, even with a
total loss of coolant. The vehicle’s range and/or speed will be reduced,
depending on vehicle load, terrain, and outside temperatures.
The instrument cluster provides warnings for each mode.
•Fail-Safe Cooling Mode:The
(Service engine
soon),
(Engine oil pressure), and(Engine coolant
temperature) indicators will be on.
Along with these warning indicators, the engine coolant temperature
gauge will read in the Hot (H) area.
If the engine coolant reaches even hotter temperatures, fail-safe
cooling mode limits engine power more and disables air conditioning.
The engine will switch to alternating cylinder operation to help cool
the engine. The engine will run rough in this mode.
If continued operation increases the engine coolant temperature to a
critical range, the engine will shut down. Steering and braking effort
will increase. Once engine coolant temperature cools, the engine can
be restarted.
•Engine Oil Overheat Mode:The
(Engine coolant temperature)
indicator will be on. The instrument cluster has no separate oil
temperature indicator.
Along with the
(Engine coolant temperature) indicator, the engine
coolant temperature gauge will read in the Hot (H) area.
Oil overheat can be triggered in severe driving conditions, such as
towing heavy loads over mountainous terrain in extreme hot
temperatures. As oil temperature increases, engine and vehicle speed
will be limited. The transmission will also shift differently.
When the engine oil has cooled, the vehicle will perform normally.

When fail-safe cooling mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. Remember that the engine is capable of completely
shutting down automatically to prevent engine damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait approximately 15 minutes for the engine to
cool.
4. Check the coolant level and replenish if low. Look for coolant leakage
in the engine compartment and under the vehicle.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
5. Restart the engine and take your vehicle to an authorized dealer.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to an
authorized dealer as soon as possible.
FUEL FILTER
For fuel filter replacement, see your authorized dealer. Refer to
scheduled maintenance informationfor the appropriate intervals for
changing the fuel filter.
Replace the fuel filter with an authorized Motorcraft part. The
customer warranty may be void for any damage to the fuel system
if an authorized Motorcraft fuel filter is not used.
WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS
Important safety precautions
WARNING:Do not overfill the fuel tank. The pressure in an
overfilled tank may cause leakage and lead to fuel spray and fire.
WARNING:The fuel system may be under pressure. If you hear
a hissing sound near the fuel filler door (Easy Fuel™ “no cap”
fuel system), do not refuel until the sound stops. Otherwise, fuel may
spray out, which could cause serious personal injury.
