oil pressure FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS 2002 10.G Owners Manual

Charging system
Illuminates when the battery is not
charging properly.
Oil pressure/Engine coolant
Illuminates when the engine coolant
temperature is above the normal
range or the engine oil pressure is
below normal range. Check the
engine oil and coolant level refer toAdding engine oilandAdding
coolantin theMaintenance and specifications chapter.
Low fuel
Illuminates when the fuel level in
the fuel tank is at, or near, empty
(refer toFuel gaugein this chapter
for more information).
Fuel reset
Illuminates when the fuel pump
shut-off switch has been triggered.
For more information, refer toFuel
pump shut-off switchin the
Roadside emergencieschapter.
Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. Refer toBulbsin the
Maintenance and carechapter.

Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the “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 immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate.
Engine oil pressure gauge
Indicates engine oil pressure. At
normal operating temperature, the
needle will be in the normal range
(the area between the “L” and “H”);
if the needle goes below the normal
range, stop the vehicle as soon as
safely possible and switch off the
engine immediately. Check the oil
level. Add oil if needed (refer to
Engine oilin theMaintenance
and specificationschapter). If the
oil level is correct, have your vehicle checked at your dealership or by a
qualified technician.

Installation
1. Install the fuel filter.
2. Lubricate the tube end with clean
engine oil meeting Ford
specification WSS-M2C153–H to
ease assembly.
•Pull on the fitting to make sure it
is fully engaged, then install
safety clip.
•Align and push the tube into the
fitting until you hear a click.
3. Remove the EFI/CFI Fuel
Pressure Gauge.
4. Install the Schrader valve cap securely.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1 600 km (1 000 miles)
of driving (engine break-in period). You will get a more accurate
measurement after 3 000 km–5 000 km (2 000 miles-3 000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theRefill capacities
section of this chapter.
Maintenance and specifications
78

Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of L/100 km (MPG)
expected on the vehicle under optimum conditions. Your fuel economy
may vary depending upon the method of operation and conditions.
