2004 FORD F650 overheating

Speedometer:Indicates the
current vehicle speed.
Engine coolant temperature
gauge:Indicates engine coolant
temperature. At normal operating
temperature, the needle will be in
the normal range (between“H”and
“C”).If it enters the red section,
the engine is overheating. Stop
the vehicle as soon as safely
possible, switch off the engine
and let the engine cool.
Never remove the coolant reservoir cap while the engine is
running or hot.
Odometer:Registers the total
kilometers (miles) of the vehicle.
Trip odometer:Registers the
kilometers (miles) of individual
journeys. To reset, depress the
control.

Hot weather operation
•Keep the engine cooling system filled with a clean, permanent coolant
solution to protect against damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
Above normal coolant temperatures could be experienced while driving
in a transmission gear ratio which lugs the engine. To correct this
problem, engine speed should be increased by downshifting in to the
next lower gear to increase engine RPM.
Starting a turbocharged engine with the vehicle on a steep grade
When starting a naturally aspirated Diesel engine when the loaded
vehicle is on a grade, the engine RPM will start to fall slightly when the
clutch is engaged, but quickly recovers as the vehicle begins moving.
Turbocharged Diesel engines act differently; once the clutch is engaged,
the engine RPM will fall significantly. When the engine RPM first falls, do
not disengage the clutch and try to increase engine RPM as this may
damage driveline components. After the initial drop in engine RPM, the
engine will recover by itself and accelerate in a normal manner.
GENERAL OPERATING INSTRUCTIONS
•Start the vehicle in motion by using the highest gear speed in the
transmission that will let the engine easily start the load without
slipping the clutch.
•Accelerate smoothly and evenly; rapid acceleration increases fuel
consumption without increasing engine performance.
•When approaching a hill, depress the accelerator smoothly to start the
incline at full power, then shift down as needed to maintain vehicle
speed.
•When going down a hill, or long steep grades, prevent over-speeding
of the engine. The engine governor has no control over engine speed
when it is being pushed by a loaded vehicle.

Do not add engine coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you
badly. Also, you can be burned if you spill coolant on hot engine parts.
Do not put engine coolant in the windshield washer fluid
container. If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
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 (an opaque 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 (see
above), to within the“cold fill range”or the“cold full”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
toCoolant condition inspectionlater in this section). 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 liter (1.0 quart) of engine coolant per
month, have your 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.

Extended life engine coolant
The cooling system in your vehicle is filled with yellow-colored
Motorcraft Premium Gold Engine Coolant meeting Ford Specification
WSS-M97B51–A1.
•Add Motorcraft Premium Gold Engine Coolant
(yellow-colored), VC-7–A (VC-7–B in Oregon).
Note:Use of Motorcraft Cooling System Stop Leak Pellets, VC-6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
•
Do not add/mix extended life coolants such as Motorcraft
Speciality Orange Engine Coolant, VC-2 (U.S.) or CXC-209
(Canada), meeting Ford specification WSS-M97B44–D, with the
factory-fill coolant, Motorcraft Premium Gold Coolant meeting
Ford Specification WSS-M97B51–A.Mixing Motorcraft Speciality
Orange Engine Coolant or any equivalent extended life engine coolant
with this factory-fill coolant can result in degraded corrosion protection.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
•
Do not use alcohol, methanol or 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.
•Do not mix with recycled coolant unless from a Ford-approved
recycling process (seeUse of Recycled Engine Coolantsection).
Coolant condition inspection
Engine cooling systems should be checked twice a year to assure proper
glycol/water concentrations. a 50/50 mixture is recommended and
provides freeze protection in weather conditions as low as–36°C (-34°F)
as well as optimum corrosion protection. For vehicle operating in
extremely cold climate, a concentration of 60% ethylene glycol will
provide freeze protection in weather conditions as low as–51°C (-59°F).
Concentrations greater than 60% glycol are not recommended.
