indicates higher water content than required.
„ NOTE: The addition of Motorcraft Cooling System Stop Leak Pellets, VC- 6,
darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.
If Motorcraft Premium Gold Engine Coolant (yellow color) VC-7- A or equivalent
meeting Ford specification WSS- M97B51-A1 has a clear or pale yellow color, this
indicates higher water content than required.
„ Dark brown can indicate unauthorized stop leak may have been used. Use
Motorcraft Cooling System Stop Leak Pellets VC- 6 or equivalent meeting Ford
specification ESE-M99B37- 5 except as noted in ES-F65E-19A511- AA only.
„ A light or reddish brown color indicates that rust may be present in the cooling
system. Flush the system and refill with the correct mixture of water and engine
coolant.
„ An iridescent sheen on top of the coolant or a milky brown color can indicate a
trace of oil is entering the system. For additional information on engine diagnosis,
refer to Section 303 - 00 .
3. If the engine coolant appearance is acceptable, test the engine coolant freezing point
range with the special tool. The freezing point should be in the range - 50°F to -10°F. If
the vehicle is driven in cold climates less than - 34°F, it may be necessary to increase the
coolant concentration to get adequate freeze protection.
„Maximum coolant concentration is 60/40.
„ Minimum coolant concentration is 40/60.
4. Check the coolant system conditions:
„If the intercooler fluid is low, add the specified coolant mixture only.
„ If the intercooler coolant fluid tests weak, add straight engine coolant until the
readings are within acceptable levels.
„ If the engine coolant tests strong, remove some of the engine coolant and add
water until readings are within acceptable levels.
5. If the concern remains after the inspection, determine the symptom(s). GO to Symptom Chart .
6. Verify the cooling system is correctly filled and bled. Refer to Supercharger Cooling System Draining, Filling and Bleeding in this section.

GENERAL PROCEDURES
Supercharger Cooling System Draining, Filling and
Bleeding
Draining
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 certain all the pressure has been released,
(still with a cloth) turn and remove the pressure relief cap.
CAUTION: The coolant must be recovered in a suitable, clean container for reuse. If the
coolant is contaminated, it must be recycled or disposed of correctly and replaced.
CAUTION: Some vehicle cooling systems are filled with 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). Others are filled with Motorcraft Premium Gold Engine Coolant
VC -7-A or equivalent meeting Ford specification WSS- M97B51-A1 (yellow color). Always fill the
cooling system with the same coolant that is present in the system. Do not mix coolant types.
NOTE: The addition of Motorcraft Cooling System Stop Leak Pellets, VC- 6, darkens Motorcraft
Premium Gold Engine Coolant from yellow to golden tan.
NOTE: Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty
or contaminated coolant requires replacement.
1. Raise and support the vehicle. For additional information, refer to Section 100 - 02 .
2. Remove the lower hose from the intercooler radiator and allow the coolant to drain.
Filling and Bleeding
CAUTION: Engine coolant provides freeze protection, boil protection, cooling efficiency
and corrosion protection to the engine and cooling components. In order to obtain these
protections, the engine coolant must be maintained at the correct concentration and fluid level
in the degas bottle.
CAUTION: Some vehicle cooling systems are filled with 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). Others are filled with Motorcraft Premium Gold Engine Coolant
VC -7-A or equivalent meeting Ford specification WSS- M97B51-A1 (yellow color). Always fill the
cooling system with the same coolant that is present in the system. Do not mix coolant types.
NOTE: The addition of Motorcraft Cooling System Stop Leak Pellets, VC- 6, darkens Motorcraft
Premium Gold Engine Coolant from yellow to golden tan.
NOTE: When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable
water. SECTION 303-

WARNING: Do not smoke or carry lighted tobacco or open flame of any type when
working on or near any fuel related components. Highly flammable mixtures are always present
and may ignite. Failure to follow these instructions may result in personal injury.
WARNING: Fuel in the fuel system remains under high pressure even when the engine is
not running. Before working on or disconnecting any of the fuel lines or fuel system
components, the fuel pressure must be relieved. Failure to follow these instructions may result
in personal injury
1. Remove the supply manifold. For additional information, refer to Supply Manifold in this section.
2. Remove the six fuel injectors from the supply manifold.
3. CAUTION: The retaining clip must be in the upper groove on the injector or the
injector may become loose.
NOTE: Inspect the two O- rings from each fuel injector. Install new O- rings as needed.
NOTE: Lubricate the new O- rings with clean engine oil to aid installation.
To install, reverse the removal procedure.
