DESCRIPTION AND OPERATION
Supercharger Cooling
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: The air that is produced from the supercharger is cooled by the intercooler.
Walter C. Avrea, the owner of patents 3,601,181 and RE 27,965, has granted Ford Motor Company
rights with respect to cooling systems covered by these patents.
The cooling system components include the:
zintercooler
z intercooler radiator (8K226)
z pressure relief cap
z degas bottle
z electric water pump (8501)
The degas bottle:
zprovides a location for system fill.
z contains coolant expansion and system pressurization.
z provides air separation during operation.
z replenishes the intercooler coolant to the system.
The intercooler coolant flows:
zfrom the intercooler to the degas bottle.
z from the degas bottle to the water pump.
z from the water pump to the intercooler radiator.
z from the intercooler radiator to the intercooler.
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.
When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable water.
To maintain the integrity of the coolant and the cooling system: SECTION 303-

DIAGNOSIS AND TESTING
Supercharger Cooling
Inspection and Verification
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.
CAUTION: Check the coolant and engine oil levels. Top off the coolant level if needed. If
there is engine coolant in the engine oil, the cause must be corrected and the oil changed or major component damage can occur. SECTION 303-

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.

Pressure Test
1. Turn the engine OFF.
2. WARNING: Never remove the pressure relief cap under any conditions while the
engine is operating. Failure to follow these instructions could result in damage to the
cooling system or engine and/or personal injury. To avoid having scalding hot coolant or
steam blow out of the cooling system, never remove the pressure relief cap from a hot
degas bottle. Wait until the engine has cooled, then wrap a thick cloth around the
pressure relief cap and turn it slowly one turn (counterclockwise). Step back while the
pressure is released from the cooling system. When certain all the pressure has been
released, remove the pressure relief cap (still with a cloth).
Check the intercooler coolant level. For additional information, refer to Supercharger Cooling System Draining, Filling and Bleeding in this section.
3. Connect the Radiator/Heater Core Pressure Tester to the degas bottle nipple. Install a pressure test pump to the quick- connect fitting of the test adapter.
4. NOTE: If the plunger of the pump is depressed too fast, an erroneous pressure reading will
result.
Slowly depress the plunger of the pressure test pump until the pressure gauge reading stops
increasing and note the highest pressure reading obtained.
5. If the pressure relief cap does not hold pressure, remove and wash the pressure relief cap in clean water to dislodge all foreign particles from the gaskets. Check the sealing surface in the
filler neck.
6. If 69 kPa (10 psi) cannot be reached, install a new pressure relief cap. If more than 12 kPa (18 psi) shows on the gauge, install a new pressure relief cap.
7. CAUTION: If the pressure drops, check for leaks at the intercooler hoses or other
system components and connections. Any leaks which are found must be corrected and
the system rechecked.
NOTE: Intercooler system is not connected to the main engine cooling system.
Pressurize the intercooler cooling system as described in Step 4 (using a pressure relief cap
that operates within the specified upper and lower pressure limits). Observe the gauge reading
for approximately two minutes; refer to General Specifications. Pressure should not drop during
this time. zIf the pressure drops and no external leak is found, the intercooler may be the cause.
Remove and inspect the intercooler. Install a new intercooler if necessary.
8. Release the system pressure by loosening the pressure relief cap. Check the coolant level and replenish, if necessary, with the correct coolant mixture. For additional information, refer to
Supercharger Cooling System Draining, Filling and Bleeding in this section.
