2003 FORD SUPER DUTY heating

For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recoverysystem, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the “cold full” level. For all other vehicles, which have a coolant
degas system with a pressurized cap, or if it is necessary to remove the
coolant pressure relief cap on the radiator of a vehicle with an overflow
system, follow these steps to add engine coolant.
To reduce the risk of personal injury, make sure the engine is
cool before unscrewing the coolant pressure relief cap. The
cooling system is under pressure; steam and hot liquid can come out
forcefullywhen the cap is loosened slightly.
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).
Slowlyturn 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 slowlywith 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 tightlyinstalled. (Cap must be tightly
installed to prevent coolant loss.)
After anycoolant has been added, check the coolant concentration, refer
toChecking Engine Coolantsection. If the concentration is not 50/50
(protection to –34° F/–36° C), drain some coolant and adjust the
concentration. It maytake 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.
Maintenance and Specifications
202

The transmission fluid should be in
this range if at normal operating
temperature (66°C-77°C
[150°F-170°F]).
The transmission fluid should be in
this range if at ambient temperature
(10°C-35°C [50°F-95°F]).
High fluid level
Fluid levels above the safe range
mayresult in transmission failure.
An overfill condition of transmission
fluid maycause shift and/or
engagement concerns and/or
possible damage.
High fluid levels can be caused by
an overheating condition.
Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normallyindicated on the dipstick and also in the
Lubricant specificationssection in this chapter.
Use of a non-approved automatictransmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 250 ml (1/2 pint) increments through the filler
tube until the level is correct.
If an overfill occurs, excess fluid
should be removed bya qualified
technician.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
