INTRODUCTION

Removal, overhaul and installation procedures (when available from manufacturer) are covered in this article. If component removal and installation is primarily an unbolt and bolt-on procedure, only a torque specification may be furnished.

Removal (Except Probe 2.5L)

1. Remove high tension leads and distributor cap. Rotate crankshaft in direction of normal rotation until piston No. 1 is at TDC of compression stroke. Disconnect negative battery cable.
2. Ensure timing marks are aligned. Disconnect distributor wiring from harness. Mark distributor rotor-to-housing and housing-to-engine position for installation reference. Remove distributor hold-down bolt(s) and clamp. Some engines may be equipped with a security-type distributor hold-down bolt.
3. If necessary, use Distributor Hold-Down Wrench (T82L-12270-A) to remove bolt. Remove distributor. Inspect distributor "O" ring and replace if necessary.

Installation (Except Probe 2.5L)

1. Ensure engine is at TDC of compression stroke. Rotate distributor rotor so reference marks nearly align. Insert distributor drive into engine.
2. When installing distributor, rotor will rotate. Ensure reference marks are aligned when distributor is fully engaged in engine. To complete installation, reverse removal procedure. Set base ignition timing. See appropriate ADJUSTMENTS article in the ENGINE PERFORMANCE section below. «ADJUSTMENTS - 4-CYL»(ref-22872) «ADJUSTMENTS - V6»(ref-22884) «ADJUSTMENTS - V8»(ref-22902)

DISTRIBUTOR OVERHAUL

Note. Overhaul is not recommended on Escort, Probe or Tracer. If distributor is defective, replace entire unit.

Disassembly

1. On models with distributor mounted ICM, remove 2 module screws. Pull right side of module down and back up distributor mounting flange to disengage module terminals from connector in distributor base. Remove module by pulling toward flange and away from distributor. CAUTION: Attempting to remove ignition module without first moving entire module toward distributor flange will break module pins at connector.
2. On all models, hold gear, and loosen shaft screws. DO NOT hold shaft. Remove screws and shaft. Using a felt-tip pen, mark shaft and gear for installation reference. Remove and discard roll pin in gear.
3. Place distributor in Axle Bearing Remover (T75L-1165-B). Press off gear using arbor press and Pinion Bearing Cone Remover (D79L-4621-A). Remove shaft. Using emery cloth, remove burrs from distributor shaft. Remove shaft from distributor assembly. (Scheme 1)or (Scheme 2).
4. Remove thrust washer from distributor (if equipped), and save for installation. Remove screw and octane rod assembly (if equipped). Remove stator assembly screws and stator.
5. Inspect base bushing, "O" ring and distributor housing for wear, cracks or other damage. If necessary, replace "O" ring. If distributor housing or bushings are worn, replace entire distributor assembly.

Scheme 1

Scheme 2

Reassembly

1. Place stator assembly over bushing, and press down to seat. Place stator connector in position. Tab should fit in notch of base, and fastening eyelets should align with screw holes. Position wires away from moving parts. Install and tighten stator screws.
2. On models with distributor mounted ICM, install octane rod through distributor base hole. Place end of rod onto same post as original stator. Install and tighten octane rod screw. On all models, lubricate distributor shaft, with light oil. DO NOT over lubricate.
3. Install shaft through base bushing. Place a 1/2" deep well socket over shaft, invert assembly and place in arbor press. Place thrust washer (if equipped) and distributor drive gear on shaft. Align marks made during removal.
4. Place a 5/8" deep well socket over shaft and gear. Press gear until holes align with holes in shaft. If holes do not line up, press gear off and try again. DO NOT try to align holes using a drift or roll pin. Insert new roll pin through gear and shaft.
5. If armature has been removed, install armature. Tighten screws. Check distributor for freedom of rotation. If armature contacts stator, replace distributor. On models with distributor mounted ICM, clean back of module and distributor contact plate.
6. Apply Silicone Dielectric Compound (D7AZ-19A331-A) to back of module, and spread evenly. Invert distributor base so stator connector is in full view. Insert module.

Disconnect inlet and outlet tubes at charge air cooler. (Scheme 11) Loosen inlet tube at alternator/power steering pump bracket. Remove charge air cooler nuts and washers. Push downward on charge air cooler to disengage retaining clips. Remove charge air cooler.

Install charge air cooler retaining clips. Install retaining nuts and washers. Ensure air boot fits on charge air cooler and no gaps exist. Install inlet and outlet tubes on charge air cooler. Tighten inlet and outlet tube nuts to specification. See TORQUE SPECIFICATIONS TABLE (V6). Start engine and check for leaks.

The oxygen sensor is equipped with a permanent pigtail, which must be protected when sensor is removed. Ensure sensor is free of contaminants, and avoid using cleaning solvents of any type. Sensor may be difficult to remove when engine temperature is less than 120°F (48°C). Always use anti-seize compound on threads prior to installation. Tighten sensor to 30 ft. lbs. (41 N.m).

SUPERCHARGER

Note. Disassembly of supercharger unit may void warranty. Supercharger cannot be overhauled. Supercharger is serviced by replacement ONLY.

Removal & Installation (3.8L SC)

1. Clean areas surrounding supercharger. Disconnect negative battery cable. Remove throttle body air inlet tubes. Remove cowl vent screens. Partially drain cooling system.
2. Remove right side spark plug wires at ignition coil. Remove all vacuum and electrical connectors from upper intake manifold and throttle body. Remove EGR tubes from EGR valve. Disconnect EGR transducer.
3. Remove throttle linkage and bracket. Disconnect speed control (if equipped). Remove supercharger drive belt. Remove charge air cooler inlet and outlet tubes. See CHARGE AIR COOLER INLET TUBE and CHARGE AIR COOLER OUTLET TUBE.
4. Remove 3 intake elbow bolts. Remove 3 supercharger retaining bolts. Lift supercharger and intake assembly from vehicle as a unit. (Scheme 11) To install, reverse removal procedure. Tighten bolts to specification. See TORQUE SPECIFICATIONS TABLE (V6).

THROTTLE POSITION (TP) SENSOR

Note. On 1.8L & 2.5L, TP sensor is adjustable. For adjustment procedure, see appropriate ADJUSTMENTS article in the ENGINE PERFORMANCE section below. TP sensor is not adjustable on all other models.

1. «ADJUSTMENTS - 4-CYL»(ref-22872)
2. «ADJUSTMENTS - V6»(ref-22884)
3. «ADJUSTMENTS - V8»(ref-22902)

Remove distributor cap, if necessary. Disconnect TP sensor from wiring harness. Mark throttle body and TP sensor for reassembly reference. Remove mounting screws and TP sensor. To install, Align tangs on TP sensor with blades on throttle shaft and install sensor on throttle body. Align marks on throttle body and TP sensor. Secure TP sensor to throttle assembly with retaining screws. Reconnect wiring.

1. Remove air cleaner outlet tube. Raise vehicle on hoist. Hold EGR valve tube to manifold connector with a wrench while disconnecting EGR valve to exhaust manifold tube. Use care not to damage EGR valve tube to manifold connector. Disconnect EGR valve to exhaust manifold tube from EGR valve and EGR valve tube to manifold connector. Lower vehicle.
2. Disconnect EGR pressure sensor hoses from EGR valve to exhaust manifold tube. Disconnect vacuum hose from EGR valve. Remove two EGR valve retaining bolts. Remove EGR valve, EGR valve gasket and EGR valve to exhaust manifold tube from vehicle.

1. Clean intake manifold sealing surface with a plastic-tipped scraper to remove any residual EGR valve gasket material. Position EGR valve to exhaust manifold tube into EGR valve and loosely connect EGR valve to exhaust manifold tube nut to EGR valve. Do not tighten EGR valve to exhaust manifold tube nut on EGR valve at this time.
2. Position EGR valve gasket, EGR valve and EGR valve to exhaust manifold tube into vehicle. Install two bolts retaining EGR valve to intake manifold. Tighten bolts to specification. See «TORQUE SPECIFICATIONS»(/ford/crown-victoria/i-1992-1997/remont/removal-installation/#engine-controls-removeinstalloverhaul) . Connect vacuum hose to EGR valve. Connect EGR pressure sensor hoses to EGR valve to exhaust manifold tube.
3. Raise vehicle. Connect EGR valve to exhaust manifold tube to EGR valve tube to manifold connector. Hold EGR valve tube to manifold connector with a wrench while tightening EGR valve to exhaust manifold tube nut. Tighten EGR valve to exhaust manifold tube nuts to specification. Lower vehicle. Install air cleaner outlet tube.
