SERVICE RECOMMENDATIONS
To help you service your vehicle:
•We highlight do-it-yourself items in the engine compartment for easy
location.
•We provide a Scheduled Maintenance Guide which makes tracking
routine service easy.
If your vehicle requires professional service, your dealership can provide
necessary parts and service. Check your “Warranty Guide” to find out
which parts and services are covered.
Use only recommended fuels, lubricants, fluids and service parts
conforming to specifications. Motorcraft parts are designed and built to
provide the best performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR VEHICLE
Be especially careful when inspecting or servicing your vehicle.
•Do not work on a hot engine.
•When the engine is running, make sure that loose clothing, jewelry or
long hair does not get caught up in moving parts.
•Do not work on a vehicle with the engine running in an enclosed
space, unless you are sure you have enough ventilation.
•Keep all lit cigarettes, open flames and other lit material away from
the battery and all fuel related parts.
If you disconnect the battery, the engine must “relearn” its idle
conditions before your vehicle will drive properly, as explained inBattery
in this chapter.
Working with the engine off
1. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
2. Turn off the engine and remove the key.
3. Block the wheels to prevent the vehicle from moving unexpectedly.

2. Turn the engine off and wait a few minutes for the oil to drain into the
oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
4. Open the hood. Protect yourself from engine heat.
5. Locate and carefully remove the
engine oil level indicator (dipstick).
6. Wipe the indicator clean. Insert the indicator fully, then remove it
again.
•If the oil level isbetween the MIN and MAX marks,the oil level is
acceptable.DO NOT ADD OIL.
•If the oil level is below the MIN mark, add enough oil to raise the level
within the MIN-MAX range.
•Oil levels above the MAX mark may cause engine damage. Some oil
must be removed from the engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the MIN and MAX ranges, add only
certified engine oil of the recommended viscosity. Remove the engine oil
filler cap and use a funnel to pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
MAX mark on the engine oil level indicator (dipstick).

4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
until three clicks can be heard.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.
Engine oil and filter recommendations
Look for this Certification
Trademark.
Use SAE 5W-30 motor oil certified for gasoline engines by the American
Petroleum Institute (API).
Motor oil displaying the API Certification Trademark will meet all
requirements for your vehicle’s engine.
Ford oil specification is WSS-M2C153-G.
Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the Scheduled Maintenance Guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, startup
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and refilled as needed. Refer to the
Scheduled Maintenance Guide for the service interval schedules:
•Hydroboost brake fluid reservoir
•Hydromax brake fluid reservoir
1. Clean the reservoir cap before removal to prevent dirt or water from
entering the reservoir.
2. Visually inspect the fluid level.
3. If necessary, add brake fluid until the level reaches MAX. Do not fill
above this line.
Maintenance and care
58

4. Use only a DOT 3 brake fluid certified to meet Ford specifications.
Refer toLubricant specificationsin theCapacities and specifications
chapter.
Brake fluid is toxic.
If you use a brake fluid that is not DOT 3, you will cause
permanent damage to your brakes.
Do not let the reservoir for the master cylinder run dry. This
may cause the brakes to fail.
Brake system fluid should be replaced on a regular basis to maintain
optimum braking performance, especially under heavy-duty driving
conditions such as frequent steep grades or heavy towing loads. Refer to
the Scheduled Maintenance Guide for the service interval schedules.
ENGINE COOLANT
Check the level of the engine
coolant in the reservoir. Refer to the
Scheduled Maintenance Guide for
service interval schedules. Be sure
to read and understandPrecautions
when servicing your vehiclein
this chapter.
COLD FILL LEVEL
Maintenance and care
59

If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become empty. If this occurs, add
engine coolant to the reservoir. For more information on engine coolant
maintenance, refer toAdding engine coolantin this chapter.
Automotive fluids are not interchangeable;do notuse engine coolant,
antifreeze or windshield washer fluid outside of its specified function and
vehicle location.
Adding engine coolant
Use only Ford Premium Engine Coolant E2FZ-19549–AA (in
Oregon, F5FZ-19549–CC, in Canada, Motorcraft CXC-10) or a
premium engine coolant that meets Ford specification
ESE-M97B44–A.
•DO NOT USE Ford Extended Life Engine Coolant
F6AZ-19544–AA (orange in color).
•DO NOT USE a DEX-COOLengine coolant or an equivalent
engine coolant that meets Ford specification WSS-M97B44–D.
•DO NOT USE alcohol or methanol antifreeze or any engine
coolants mixed with alcohol or methanol antifreeze.
•DO NOT USE supplemental coolant additives in your vehicle.
These additives may harm your engine’s cooling system.
•DO NOT MIX recycled coolant and conventional coolant
together in your vehicle. Mixing of engine coolants may harm
your engine’s cooling system.
•The use of an improper coolant may harm engine and cooling
system components and may void the warranty of your vehicle’s
engine cooling system.
•Use only the type of coolant with which your vehicle was
originally equipped. If you are unsure which type of coolant
your vehicle requires, contact your local dealer.
Do not put engine coolant in the container for the windshield
washer fluid.
If sprayed on the windshield, engine coolant could make it difficult to see
through the windshield.
