Adding and replacing engine coolant-Caterpillar 3126 B engine
Refer to the engine operator’s manual for engine cooling system
information.
FAN CLUTCHES
Your vehicle’s cooling system is equipped with a viscous variable speed
fan clutch.
•The fan clutch helps control cooling, increase performance, improve
fuel economy and reduce noise.
•The fan clutch is controlled by bimetallic spring sensors. Do not
tamper with these sensors as this may change their calibration or keep
the fan clutch from operating at all.
Stay clear of the fan/fan area while the engine is running or
possible personal injury may occur.
CHECKING AND ADDING POWER STEERING FLUID
Checking power steering fluid level
Check the power steering fluid level using the following procedure. Refer
to the Scheduled Maintenance Guide for the recommended service
intervals. If adding fluid is necessary, use only MERCONAT F.
1. Set the parking brake, shift into N
(Neutral) (automatic transmission)
or 1 (First) (manual transmission)
and turn the engine off.
2. Open the hood.
3. Clean the top of the power
steering fluid reservoir.
4. Remove the dipstick from the
reservoir and wipe the dipstick
clean.
5. Reinstall the dipstick. Remove it again and check the fluid level.
Maintenance and care

•If the fluid temperature is at
approximately 20°C-49°C (68°F
- 120°F) (fluid cool or warm to
the touch), check the COLD
side of the dipstick. The fluid
level should be within the FULL
range
•If the fluid level is below the ADD
line, add fluid in small amounts, continuously checking the level until
it reaches the proper level.
•If the fluid temperature is at
approximately 80°C - 110°C
(176°F - 230°F) (fluid too hot
to touch), check the HOT side
of the dipstick. The fluid level
should be within the FULL range.
•If the fluid level is below the ADD
line, add fluid in small amounts,
continuously checking the level until it reaches the proper level.
A low fluid level may indicate a leak in the power steering system.
Inspect the power steering system and repair the leak. If necessary, see
your dealer or a qualified service technician.
To avoid damage to the power steering system,do notoperate the
vehicle with a low power steering fluid level.
Whenever the dipstick is installed, make sure it is properly seated and
tightened securely.
TRANSMISSION FLUID
Always dispose of used automotive fluids in a responsible manner.
Follow your community’s standards for disposing of these types of fluids.
Call your recycling center to find out about recycling automotive fluids.
Automatic transmission fluid
Refer to your Allison Automatic Transmission Operator’s Manual for
scheduled intervals for transmission fluid checks and changes. Your
transmission does not consume fluid. However, the fluid level should be
checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.

Maintenance and care

Transmission fluid level should be checked by your dealer or a qualified
service technician.
If you must add transmission fluid, make sure the correct type of fluid is
being used. The type of fluid used is indicated in your Allison Automatic
Transmission Operator’s Manual.
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
Manual transmission fluid
Refer to your Scheduled Maintenance Guide for transmission fluid level
checks and fluid change intervals.
Your manual transmission may be filled with an optional synthetic fluid
which allows the use of extended service intervals. A tag on the filler
plug will identify the use of the synthetic fluid.
Use only fluid that meets Ford specifications (refer toLubricant
specificationsin theCapacities and specificationchapter).
Use of a non-approved transmission fluid may cause internal
transmission component damage.
For location of the transmission filler plug, refer to your transmission
operator’s manual orTransmission Refill Capacitiesin theCapacities
and specificationschapter.
Check your transmission fluid level using the following procedure:
1. Park the vehicle on level ground.
2. Set the parking brake and shift into 1 (First) and turn the engine off.
3. Clean any dirt from around the filler plug.
4. Remove the filler plug and inspect the fluid level.
5. The fluid level should be up to the bottom of the filler plug opening.
6. If necessary, add enough fluid through the filler plug opening so that
the fluid level is at the bottom of the opening.
7. Clean and install the filler plug securely.
Drain and refill your transmission fluid using the following procedure:
1. Drain the transmission while the fluid is warm.
2. Park the vehicle on level ground.
3. Set the parking brake and shift into 1 (First) and turn the engine off.
Maintenance and care

4. Clean any dirt from around the filler and drain plugs.
5. Remove the filler and drain plugs and drain the fluid into a suitable
container. Dispose all used automotive fluids in a responsible manner
following your local authorized standards.
6. Clean and install the drain plug securely.
7. Add enough fluid through the filler plug opening so that the fluid level
is up to the bottom of the opening.
8. Clean and install the filler plug securely.
REAR AXLE LUBRICANT
Refer to your Scheduled Maintenance Guide for rear axle lubricant level
checks and lubricant change intervals.
Your rear axle may be filled with an optional synthetic lubricant which
allows the use of extended service intervals. A tag on the filler plug will
identify the use of the synthetic lubricant.
Use only a lubricant that meets Ford specifications (refer toLubricant
specificationsin theCapacities and specificationchapter).
Use of a non-approved rear axle lubricant may cause internal axle
component damage.
Check your rear axle lubricant level using the following procedure:
1. Park the vehicle on level ground.
2. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission) and turn the engine off.
3. Clean any dirt from around the rear axle filler plug.
4. Remove the filler plug and inspect the lubricant level.
5. The lubricant level should be up to the bottom of the filler plug
opening.
6. If necessary, add enough lubricant through the filler plug opening so
that the lubricant level is at the bottom of the opening.
7. Clean and install the filler plug securely.
Drain and refill your rear axle lubricant using the following procedure:
1. Drain the rear axle while the lubricant is warm.
2. Park the vehicle on level ground.
