. Remove outer crankshaft pulley attaching bolts, then outer stiffener and spacer. Remove inner pulley
and baffle plate. Remove bolts retaining upper and lower cover halves to engine front. Remove both covers. See Fig. 2
.
2. Mark timing belt direction of rotation for installation reference. Remove timing belt tensioner pulley bolt. Remove tensioner pulley,
spring, and spring cover. Remove timing belt.
Installation
1. Ensure timing belt and sprockets are clean, and not worn or damaged. Align crankshaft and camshaft timing marks. See Fig. 3 . Position
belt onto sprockets in original running direction.
2. Install timing belt tensioner spring, spring cover, and pulley. To complete installation, reverse removal procedure. Tighten all bolts and
nuts to specification. See TORQUE SPECIFICATIONS
. Adjust drive belts to proper tension.

1991 ENGINE PERFORMANCE Ford/Mercury Rem oval, Overhaul & Installation
INTRODUCTION
Removal, overhaul and installation procedures 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.
IGNITION SYSTEM
DISTRIBUTOR
Removal
Disconnect negative battery cable. On Capri, disconnect vacuum hose from vacuum control unit. Disconnect coil wire from distributor cap.
Remove screws and distributor cap. Disconnect electrical connectors. Mark position of distributor housing to cylinder head for reassembly.
Remove distributor mounting bolts and distributor.
Installation
To install, reverse removal procedure. Install new "O" ring if damaged or worn. Insert distributor and rotate until offset drive tangs engage
camshaft slots. See Fig. 1
, Fig. 2 or Fig. 3 . Check and adjust timing as required.

To install, reverse removal procedure. Use NEW intake plenum-to-intake manifold gasket. Tighten bolts to specification, see TORQUE
SPECIFICATIONS at end of article.
OXYGEN (O2) SENSOR
Removal & Installation
Disconnect negative battery cable. Disconnect wire harness connector, and remove oxygen sensor. If exhaust sensor is difficult to remove, use
rust penetrant to avoid possible damage to exhaust threads. If new sensor is not pre-coated with anti-seize, apply anti-seize compound to
sensor threads. DO NOT remove anti-seize from sensor. To install, tighten sensor and attach wire harness connector.
THROTTLE BODY
Removal & Installation
Drain radiator and remove negative battery cable. Remove resonance chamber. Disconnect throttle cable. Remove air duct. Mark all coolant
and vacuum hoses for reassembly reference and remove from throttle body. Disconnect throttle position sensor/switch connector. Remove
throttle body nuts and bolts. Remove throttle body and gasket. To install, reverse removal procedure using NEW throttle body-to-intake
plenum gasket.
THROTTLE POSITION SENSOR/SWITCH
Removal & Installation
Disconnect negative battery cable. Disconnect throttle position sensor/switch connector. Remove attaching bolts. Remove sensor/switch from
throttle body. To install, reverse removal procedure.
