cooling FORD F150 2004 11.G User Guide

How fail-safe cooling works
If the engine begins to overheat:
²The engine coolant temperature
gauge will move to the red (hot)
area.
²The mini message center (if
equipped) will indicate ªCheck
Gaugesº, refer toWarning Lights
and Chimesin theInstrument Clusterchapter.
²The message center (if equipped) will indicate a system warning, refer
toMessage Centerin theDriver Controlschapter.
²The ªService Engine Soonº indicator light 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.
When this occurs the vehicle will still operate. However:
²The engine power will be limited.
²The air conditioning system will be disabled.
Continued operation will increase the engine temperature:
²The engine will completely shut down.
²Steering and braking effort will increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high speed
operation and the engine will run rough. 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 a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.

4Approximate dry fill capacity including transmission fluid cooling
system, actual refill capacities will vary based on vehicle application and
transmission fluid cooling system (i.e. coolers size, cooling lines. auxiliary
cooler capacities). The amount of transmission fluid and fluid level
should be set by the indication on the dipstick's normal operating range.
5Your vehicle's rear axle is filled with a synthetic rear axle lubricant and
is considered lubricated for life. These lubricants do not need to be
checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle lubricant should
be changed any time the rear axle has been submerged in water.
6Service refill capacity is determined by filling the axle to 6-14 mm
(1/4-9/16 inch) below the bottom of the filler hole with the vehicle on a
level surface.
Add 118 ml (4 oz.) of FEHP Friction Modifier, XL-7 or equivalent, for
complete fill of 8.8 inch and 9.75 inch Traction-Lok axles.
7Service refill capacity is determined by filling the axle to the bottom of
the filler hole with the vehicle on a level surface.
For 10.25 inch Traction-Lok axles, use 3.1L (6.5 pints) of Motorcraft SAE
75W-90 Fuel Efficient High Performance Synthetic Rear Axle Lubricant
and 118 ml (4 oz.) of FEHP Friction Modifier XL-7 or equivalent.
8Use of synthetic or synthetic blend motor oil is not mandatory. Engine
oil need only meet the requirements of Ford specification
WSS-M2C153±H and the API Certification mark.
