2000-2006 Lincoln LS Service & Repair Manual

2000-01 ENGINES 3.9L V8 - VIN A ENGINE IDENTIFICATION Engine may be identified by eighth character of Vehicle Identification Number (VIN). VIN is located on top of instrument panel, near lower left corner of windshield. An emission calibration number is located on driver's door or door-post pillar. This label identifies engine calibration number, engine code and revision label. Engine code label is located on valve cover. Label contains engine calibration number, engine build date, plant code and engine code. Information from labels are required when ordering replacement parts. ENGINE IDENTIFICATION CODES ADJUSTMENTS VALVE CLEARANCE ADJUSTMENT 1. Disconnect negative battery cable. Remove valve covers. See VALVE COVERS under REMOVAL & INSTALLATION. Remove spark plugs. Rotate engine by rotating crankshaft as necessary to bring each valve to base circle. Using a feeler gauge, measure intake and exhaust valve clearance, between camshaft base circle and valve tappet. See VALVE ADJUSTMENT SPECIFICATIONS table. 2. If clearance is not within specification, remove timing chains. See TIMING CHAIN under REMOVAL & INSTALLATION. Remove camshaft. See CAMSHAFT under REMOVAL & INSTALLATION. Remove shim. Select shims as follows: Measured Clearance + Base Shim Thickness - Desired Clearance = Required Shim Thickness. Install appropriate replacement shim to obtain specified clearance. Repeat procedure for each valve. Install camshaft. See CAMSHAFT under REMOVAL & INSTALLATION. Measure new valve clearances and ensure they are within specification. Install timing chains. See TIMING CHAIN under REMOVAL & INSTALLATION. Install valve covers. See VALVE COVERS under REMOVAL & INSTALLATION. VALVE ADJUSTMENT SPECIFICATIONS Engine Code 3.9L DOHC SFI A NOTE: Valve shims are not repairable with camshafts in place. Failure to measure all clearances with camshafts in place will cause unnecessary repetition of this procedure. Application (1) In. (mm) Intake Clearance Range .0070-.0086 (.18-.22) 2000 Lincoln LS 2000-01 ENGINES 3.9L V8 - VIN A 2000 Lincoln LS 2000-01 ENGINES 3.9L V8 - VIN A

TROUBLE SHOOTING REMOVAL & INSTALLATION FUEL PRESSURE RELEASE & FUEL LINE CONNECTIONS 1. Disconnect battery ground cable. Remove fuel cap to release fuel tank pressure. Using EFI Pressure Gauge (T80L-9974-B), release fuel pressure from fuel-pressure relief valve on fuel rail. 2. To disconnect fuel lines, remove retaining clip from outside of fuel line coupling. Use Spring Lock Coupling Remover (D87L-9280-A) for 3/8" line or (D87L-9280-B) for 1/2" line. Install spring lock coupling remover on fuel line coupling so it enters cage opening. 3. Push spring lock coupling remover into cage opening to release female fitting from garter spring. Pull couplings apart. Remove spring lock coupling remover. 4. When installing fuel lines, install NEW "O" rings on fuel lines. Use only specified fuel resistant "O" rings (Black). Before installing, lightly coat "O" rings with clean engine oil. Clean fittings, and replace garter spring (if necessary). Fit female fitting to male fitting and push until garter spring snaps over flared end of female fitting. 5. Ensure lines are locked together and garter spring is over female fitting flared end. Install retaining clip. Ensure horseshoe portion of clip is over coupling. DO NOT install retaining clip over rubber fuel line. Desired .0078 (.20) Exhaust Clearance Range .0090-.0106 (.23-.27) Desired .01 (.25) (1) Perform valve adjustment with engine cold. NOTE: To trouble shoot mechanical engine components, see appropriate table in TROUBLE SHOOTING article in GENERAL INFORMATION. NOTE: For reassembly reference, label all electrical connectors, vacuum hoses and fuel lines before removal. Place mating marks on engine hood and other major assemblies before removal. CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery. WARNING: Fuel system is under pressure. Pressure must be released before servicing fuel system components. 2000 Lincoln LS 2000-01 ENGINES 3.9L V8 - VIN A
