COOLING SYSTEM

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). Other vehicles 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. The addition of Motorcraft Cooling System Stop Leak Pellets, VC-6, darkens Motorcraft Premium Gold Engine Coolant from Yellow to Golden Tan. When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable water. 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. 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. 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.

COOLING SYSTEM BLEEDING

1. Fill cooling system at degas bottle with 50/50 mixture of coolant and water. Turn heater controls to maximum and set air discharge to instrument panel vents. Turn blower to high. Pause several minutes for circulation. Start engine and allow to idle. While engine is idling, feel for hot air at instrument panel vents. If air discharge remains cool and coolant temperature gauge does not move, coolant level is low. Stop engine and allow it to cool. Top off coolant as necessary.
2. Start engine and allow it to idle until normal operating temperature is reached. Hot air should discharge from instrument panel vents. Coolant temperature gauge should maintain a stable reading in middle of range. Upper radiator hose should feel hot to touch. Stop engine and allow it to cool. Check for coolant leaks. Top off coolant as necessary.

IGNITION SYSTEMS

Note. Engine design precisely locates Crankshaft Position (CKP) sensor. No CKP sensor adjustment is necessary.

Note. If knock sensor removal and installation is primarily an unbolt and bolt-on procedure, only a torque specification is furnished. See TORQUE SPECIFICATIONS .

Safe Fuel Handling Practices

Fire

1. Report all fires to proper authorities.
2. Flames from methanol or methanol-gasoline blends can be invisible.
3. Know locations of portable fire extinguishers, fire blankets, fire alarms and eye/wash shower facilities and learn how to use them.
4. Use a "B" or "AFFF" (light water) type fire extinguisher to fight flammable liquid fires.

First Aid

1. If gasoline has been swallowed, do not induce vomiting. Seek medical attention immediately!
2. If methanol or a methanol/gasoline blend has been swallowed, induce vomiting under the direction of a physician or Poison Control Center. Seek medical attention immediately!
3. When overcome by vapors, if safe, move victim to fresh air. If not breathing, give artificial respiration or CPR (Cardiopulmonary Resuscitation) as appropriate. Seek medical attention immediately!
4. If splashed in eyes, flush with large amounts of water for 15 minutes. Remove contact lenses, if worn. Seek medical attention.
5. If splashed on skin, remove contaminated clothing. Wash skin thoroughly with soap and water.

Health

1. All fuels can be harmful or fatal if swallowed.
2. Be aware, if fuel is swallowed, onset of serious health effects can be delayed 12 to 24 hours.
3. Fuels and products containing methanol (e.g. windshield washer fluid) can cause blindness if swallowed.
4. All fuel vapors can be harmful if inhaled.
5. All fuels can be harmful if absorbed through skin.
6. All fuels are irritating to eyes and respiratory system.
7. Some fuels made with gasoline contain benzene which is a cancer causing agent.

Handling

1. Use flammable liquid handling precautions.
2. Wear chemical goggles and nitrile gloves (additional protective clothing and equipment may be necessary in some instances).
3. Keep flammable liquids in approved, labeled, closed containers.
4. Use in well ventilated areas and control vapors. Be aware that vapors are not visible, are heavier than air, can travel along floor, and will settle in lower areas.
5. When transferring flammable liquids, bond receiving container to source and ground source to earth.
6. DO NOT smoke or use heat or spark producing equipment near vapors.
7. DO NOT eat, smoke or drink where these products are handled, processed or stored.
8. Never siphon by mouth.
9. Wash hands thoroughly after handling any fuel.

Spills

1. Notify proper authorities in the event of any spill you have not been trained to clean up.
2. Stop, contain, and clean up small spills with an absorbent material.

FUEL SYSTEM PRESSURE RELEASE

2.0L

Remove fuel filler cap to release fuel tank pressure. Remove fuel pump relay, located in left side engine compartment relay panel. Start engine and allow to idle until engine stalls. Crank engine twice to ensure system pressure is released. Turn ignition off. Install fuel pump relay.

3.0L

Remove fuel filler cap to release fuel tank pressure. Remove pressure relief valve (Schrader valve) cap located on fuel injection manifold rail. Connect Fuel Pressure Gauge (310-012) to pressure relief valve. Place fuel pressure gauge hose in suitable container. Slowly open manual valve on fuel pressure gauge to relieve system pressure.

Push Connect Coupling

1. Release fuel pressure. See «FUEL SYSTEM PRESSURE RELEASE»(ref-142374-S33368894952002073100000). Disconnect safety clip from male hose. (Scheme 2) Install Fuel Line Disconnect (T90T-9550-S) and push it into fitting. Separate fittings.
2. Before installation, lubricate tube end with clean engine oil. Align tube to fitting and push until a click is heard. Pull on fitting to ensure engagement. Install safety clip.

Scheme 2

"R" Clip Coupling

1. Release fuel pressure. See «FUEL SYSTEM PRESSURE RELEASE»(ref-142374-S33368894952002073100000). Remove shipping tab by bending tab downward. Spread "R" clip and push clip into fitting. (Scheme 3) Separate fitting from tube.
2. Before installation, lubricate male tube end with clean engine oil. Insert "R" clip into fitting. Align tube and fitting. Insert tube into fitting and push together until a click is heard. Pull on connection to ensure engagement.

Scheme 3

Spring Lock Coupling

1. Release fuel pressure. See «FUEL SYSTEM PRESSURE RELEASE»(ref-142374-S33368894952002073100000). Place indicated spring lock coupler over coupling. See «SPRING LOCK COUPLER IDENTIFICATION»(ref-142374-S11605066702002073100000) table. To release female fitting from garter spring, push coupler along tube into coupling. (Scheme 4)
2. Pull spring lock coupling apart. Remove coupler from disconnected spring lock coupling. Check for damaged garter spring and "O" rings. Wipe end of lines with clean cloth.
3. To install, place NEW "O" rings onto tube. Lubricate ends of lines with clean engine oil. Locate White indicator ring (if equipped), which may have slipped down length of tube. Insert White indicator ring into cage of male fitting.
4. Push fitting together with a slight twisting motion. White indicator ring will pop free of cage to indicate that male fitting is properly seated over flared end of female fitting.

SPRING LOCK COUPLER IDENTIFICATION

Scheme 4

Camshaft Position (CMP) sensor is used for timing pulsing of fuel injectors. CMP sensor signal is also used by Powertrain Control Module (PCM) to determine firing of spark plugs. See CAMSHAFT POSITION SENSOR under EMISSIONS SYSTEMS & SUBSYSTEMS .

EVAPORATIVE EMISSIONS SYSTEM SAFETY PRECAUTIONS

VAPOR TUBE FITTINGS

Disconnect battery ground cable. Disconnect vapor tube from the fitting. Squeeze fitting. Disconnect vapor tube from fitting. Inspect fitting and tube for damage. Remove any dirt or obstructions. Push tube into fitting until it snaps in place. Pull on the connection to make sure the fitting is secure.

AFTER REPAIR PROCEDURE

Perform leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST under SYSTEM TESTS (EVAPORATIVE EMISSION) in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Perform drive cycle. See EVAPORATIVE EMISSION LEAK CHECK MONITOR under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.

Note. If cylinder head temperature sensor removal and installation is primarily an unbolt and bolt-on procedure, only a torque specification is furnished. See TORQUE SPECIFICATIONS .
