2003 FORD MUSTANG engine coolant

1. To maintain the integrity of the coolant and the cooling system:
1. Add Motorcraft Premium Engine Coolant VC-4- A (in Oregon VC-5, in Canada CXC-10)
or equivalent meeting Ford specification ESE-M97B44- A (green color), or Motorcraft
Premium Gold Engine Coolant VC-7- A or equivalent meeting Ford specification WSS-
M97B51- A1 (yellow color). Use the same coolant that was drained from the cooling
system. Do not mix coolant types.
2. Do not add/mix orange-colored Motorcraft Speciality Orange Engine Coolant VC- 2 or
equivalent meeting Ford specification WSS-M97B44- D. Mixing coolants may degrade the
coolant's corrosion protection.
3. Do not add alcohol, methanol, brine, or any engine coolants mixed with alcohol or
methanol antifreeze. These can cause engine damage from overheating or freezing.
4. Do not mix with recycled coolant unless it meets the requirements of Ford specification ESE- M97B44- A or WSS-M97B51- A1. Not all coolant recycling processes meet these
Ford specifications. Use of such coolants can harm the engine and cooling system
components.
2. Fill the degas bottle. Use Motorcraft Premium Engine Coolant VC-4- A (in Oregon VC-5, in
Canada CXC- 10) or equivalent meeting Ford specification ESE-M97B44- A (green color), or
Motorcraft Premium Gold Engine Coolant VC-7- A or equivalent meeting Ford specification
WSS- M97B51- A1 (yellow color). Use the same coolant that was drained from the cooling
system. Do not mix coolant types.
3. Start the engine and allow to run until coolant circulation is observed in the intercooler degas bottle. Absence of circulation indicates air is trapped in the system.
zTurn the engine off.
4. Add coolant as needed. Use Motorcraft Premium Engine Coolant VC -4-A (in Oregon VC-5, in
Canada CXC- 10) or equivalent meeting Ford specification ESE-M97B44- A (green color), or
Motorcraft Premium Gold Engine Coolant VC-7- A or equivalent meeting Ford specification
WSS- M97B51- A1 (yellow color). Use the same coolant that was drained from the cooling
system. Do not mix coolant types.
5. Repeat the above procedure to make sure all entrapped air is released. Klj . 2 ba

GENERAL PROCEDURES
Supercharger Cooling System Flushing
1. WARNING: Never remove the pressure relief cap while the engine is operating or
when the cooling system is hot. Failure to follow these instructions can result in damage
to the cooling system or engine or personal injury. To avoid having scalding hot coolant
or steam blow out of the degas bottle when removing the pressure relief cap, wait until
the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it
slowly. 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) turn and remove the pressure
relief cap.
Once pressure is released, remove the pressure relief cap.
2. Drain the cooling system. For additional information, refer to Supercharger Cooling System Draining, Filling and Bleeding in this section.
3. NOTE: Refer to the cooling system flusher manufacturer's operating instructions for specific
vehicle hook- up.
Using an appropriate cooling system flusher, flush the intercooler cooling system.
Use Premium Cooling System Flush VC- 1 meeting Ford specification ESR-M14P7-A.
4. Fill the cooling system. For additional information, refer to Supercharger Cooling System Draining, Filling and Bleeding in this section.

Component Tests
Drive Belt Noise/Flutter
Drive belt chirp occurs due to pulley misalignment or excessive pulley runout. It can be the result of a
damaged pulley or an incorrectly aligned pulley.
To correct, determine the area where the noise comes from. Check each of the pulleys in that area
with a straightedge to the crankshaft pulley, looking for accessory pulleys out of position in the fore/aft
direction or at an angle to the straightedge.
Drive belt squeal is an intermittent noise that occurs when the drive belt slips on a pulley during certain
conditions, such as: engine start up, rapid engine acceleration, or A/C clutch engagement.
Drive belt squeal can occur:
zif any of the accessories are damaged, have a worn or damaged bearing, internal torsional
resistance above normal. All accessories should be rotatable by hand in the unloaded condition.
If not, inspect the accessory.
z if fluid gets on the drive belt. This includes power steering fluid, engine coolant, engine oil or air
conditioning system lubricant. If fluid does get on the drive belt during service, clean the drive
belt with soap and water and thoroughly rinse with clean water.
z NOTE: The drive belt tensioner arm should rotate freely without binding.
if the drive belt is too long. A drive belt that is too long will allow the drive belt tensioner arm to
go all the way to the arm travel stop under certain load conditions, which will release tension to
the drive belt. If the drive belt tensioner indicator is outside the installation wear range window,
install a new drive belt.
z if the drive belt tensioner is worn or damaged.
Belt Tension
NOTE: Drive belt tension is not adjustable.
The drive belt tensioner automatically adjusts drive belt tension. Symptom Chart Condition
