Timing Belt & Camshaft Timing Procedure: Installation
NOTE:
The camshaft timing procedure has been updated by TSB bulletin No. 47-61-34, dated December, 1994. Before proceeding, see SECTION 6A9 - REVISED CAMSHAFT TIMING PROCEDURE
for possible updated information.
NOTE:
Tools required: Cam Hold Down (J-38613-A).
- Install intermediate drive sprocket and all camshaft sprockets with taper lock rings FINGER TIGHT. Install timing belt in a counterclockwise direction around sprockets. Ensure timing belt teeth are fully engaged with all sprockets. Tighten tensioner pulley bolt to specification. See TORQUE SPECIFICATIONS .
- If actuator oil has been lost, fill actuator with SAE 5w30 Mobil 1 (or equivalent) synthetic engine oil through end hole. Fill to bottom of plug hole, only when actuator is fully retracted, and pin is installed. Install rubber end plug into rear of the actuator assembly, push until flush and snapped into place. Make sure end plug has sealed against the case. Inspect bushings and appropriate holes to make sure they are clean. Install actuator bushing into side plate. DO NOT lubricate.
- Install timing belt actuator and actuator side plate. Torque to specification. Rotate pulley assembly into belt a maximum of 132 INCH lbs. (15 Nm.) to allow engagement of actuator shaft into pulley arm socket. Pull lock pin and discard. This releases tensioner. Torque tensioner pulley assembly to 132 INCH lbs. (15 Nm.) counterclockwise to seat pulley into belt. Tighten both right hand (rear bank) camshaft sprocket bolts to 96 ft. lbs. (130 Nm). Remove Cam Hold Down from right hand (rear bank) camshaft carrier. Rotate crankshaft 360 degrees clockwise while looking at front of engine and align crankshaft reference marks. Make sure both right hand (rear bank) camshaft flats are DOWN. Tighten both left hand (front bank) camshaft sprocket bolts to 96 ft. lbs. (130 Nm).
- Remove Cam Hold Down from left hand (front bank) camshaft carrier. Rotate crankshaft 720 degrees clockwise while looking at front of engine to seat timing belt, and VERIFY correct timing by making sure both camshaft flatspots are UP on one bank, and DOWN on the opposing bank. See Fig 8.
- Install camshaft carrier covers and bolts. Torque bolts to specification. Install breather hose from rear camshaft cover, and crankcase vent from breather manifold. Install timing belt covers and bolts. Tighten bolts to specification. Install fuel line bracket and bolt. Tighten bolt to specification. Install wiring harness cover at right strut tower.
- Install spark plug wires. Install PCM electrical connectors. Install power steering lines to pump. Install serpentine belt and tensioner. Tighten serpentine belt tensioner bolt to specification. Install coolant recovery tank. Install upper intake manifold, bolts, and nuts. Tighten to specification. See TORQUE SPECIFICATIONS . Install power brake vacuum hose and wiring loom bracket for rear spark plug wires.
- Install vacuum lines to upper intake manifold tee. Connect electrical connections to canister purge solenoid and map sensor. Install EGR valve and torque bolts to specification. Connect electrical connectors to EGR. Install PCV valve and vacuum line to throttle body. Install heater hose and bracket to lower intake manifold. Install fuel mounting bracket and bolt, tighten to specification. Connect fuel lines to fuel rail and install fuel rail cover. Connect accelerator and cruise control cables to throttle body. Install air cleaner assembly. Refill cooling system and bleed. See COOLING SYSTEM BLEEDING . Fill power steering system. Install negative battery cable.
