coolant temperature FORD E SERIES 1999 4.G 7.3L Diesel Supplement Manual

After changing the fuel filter, the engine will purge the trapped air as it
runs. Engine may run roughly and smoke until the air is completely
eliminated.
ENGINE OIL
Checking engine oil level
Because it is normal to add some oil between oil changes, check your
engine oil level each time you stop for fuel. To check the engine oil level
consistently and accurately, the following procedure is recommended:
1. Have engine at normal operating temperature (at least into the
NORMAL range on the engine coolant temperature gauge).
2. Park the vehicle on a level surface, then turn off the engine and open
the hood.
4. Allow at least20 minutesafter engine shutdown to assure that the oil
contained in the upper parts of the engine has returned to the oil pan.
5. Protecting yourself from engine
heat, pull out the dipstick, wipe it
clean and reinsert fully.
6. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
7. Maintain the oil level between ADD and OPERATING RANGE on the
dipstick by adding oil as required. The distance from ADD to
OPERATING RANGE on the dipstick represents 1.9L (2 quarts). Do not
overfill. If the oil level exceeds OPERATING RANGE, oil consumption
may result.

coolant to ªwear outº in a shorter time. Ford recommends an interim
service interval performed at 12 months or 24 000 km (15 000 miles),
whichever occurs first. Add 237±295 ml (8±10 oz.) of supplemental
coolant additive FW-15 to the cooling system. For vehicles with extensive
idling time, add 237±295 ml (8±10 oz.) of coolant additive FW-15 after
every 500 hours of operation.
Operating engine with insufficient coolant and/or coolant additive can
cause severe engine damage.
Failure to follow these instructions could result in serious
personal injury from hot coolant or steam blow out and/or
damage to the cooling system or engine. Never remove the coolant
bottle cap under any circumstances while the engine is operating.
Switch off the engine and wait until it has cooled. Wrap a thick cloth
around the cap and turn it slowly while the pressure is relieved. Step
back while the pressure is released from the cooling system. When you
are sure all the pressure has been released, still with a cloth Ð turn
and remove it. Stand clear of the opening. Hot coolant may splash out.
Whenever coolant level checks are made, check condition of coolant
bottle cap rubber seal. Make sure it is clean and free of any dirt
particles. Rinse off with water, if necessary. When replacing cap on
coolant bottle, also make sure coolant bottle neck seal is clean. Check
that overflow hose is not kinked.
Coolant specification
Use only a permanent-type coolant that meets Ford Specification
ESE-M97B44±A such as Ford Premium Cooling System Fluid
E2FZ-19549±AA. Do not use alcohol or methanol antifreeze or mix them
with the specified coolant.
Use of the wrong coolant may cause radiator and/or engine damage.
Plain water may be used in an emergency, but replace it with the
specified coolant as soon as possible to avoid damage to the system. With
only water in the system, do not let the engine run hot or remain parked
in temperatures below 0ÉC (32ÉF).
Coolant conditioner (liquid)
A supplemental coolant additive FW-15 has been added to the coolant in
this engine.
