Preparation
- Park vehicle on level surface and engage parking brake. Chock rear wheels.
- Disconnect negative battery cable, then positive cable. Remove battery from vehicle.
- Drain engine oil completely and remove oil filter. Install drain plug with new crush washer.
- Drain coolant from radiator petcock and engine block drains into appropriate containers.
- Raise and secure vehicle on jack stands at frame rails (all four corners).
- Remove front skid plate and lower engine splash shield if equipped.
- Relieve fuel system pressure by removing fuel pump fuse and cranking engine until it stalls.
- Have AC system professionally recovered and evacuated.
- Place reference marks on hood hinges, then remove hood with assistant.
- Remove engine air intake system including air box and intake tube.
Procedure
- 1Remove cooling system componentsRemove radiator upper and lower hoses from engine. Disconnect coolant overflow hose. Remove radiator fan shroud mounting bolts and lift fan/shroud assembly out as a unit. Disconnect transmission cooler lines from radiator. Remove radiator mounting bolts and lift radiator out of vehicle. Cap transmission cooler lines to prevent contamination.
- 2Disconnect fuel and EVAP linesUsing fuel line disconnect tools, separate fuel supply and return lines at engine connections. Disconnect EVAP purge line and canister vent line from engine. Plug all open fuel lines to prevent contamination and fuel spillage.⚠️Have fire extinguisher nearby. Fuel will spray during disconnection even after pressure relief.
- 3Remove accessory drive componentsRemove serpentine belt by rotating tensioner clockwise. Disconnect AC compressor electrical connector and remove compressor mounting bolts. Secure compressor to frame without disconnecting lines. Disconnect alternator wiring and remove alternator mounting bolts, then remove alternator. Disconnect power steering pump lines, remove pump mounting bolts, and set pump aside.Torque specAC Compressor Bolts25 Nm (18 lb-ft)Alternator Mounting Bolts50 Nm (37 lb-ft)Power Steering Pump Bolts25 Nm (18 lb-ft)
- 4Disconnect electrical systemsLabel and disconnect all engine electrical connectors including: both O2 sensors on each bank, MAF sensor, throttle body connector, ignition coil connectors (all 8), fuel injector harness, camshaft position sensors (both banks), crankshaft position sensor, oil pressure sender, coolant temperature sensors, knock sensors, and VVT solenoids. Disconnect main engine harness connector at firewall. Remove harness from any mounting clips on engine.
- 5Remove exhaust system connectionsSpray exhaust manifold studs with penetrating oil. Working from center studs outward (hot to cold), remove exhaust manifold nuts from both banks where Y-pipe connects. Separate Y-pipe from manifolds and support exhaust system with wire or stands. If removing manifolds, apply this same hot-to-cold sequence.Torque specExhaust Manifold Nuts30 Nm (22 lb-ft)
- 6Disconnect throttle body and vacuum systemsDisconnect throttle body coolant hoses (mark for proper reinstallation). Remove throttle body and intake manifold connections. Label and remove all vacuum lines including brake booster vacuum line, PCV hoses, and any remaining vacuum accessories. Remove heater hoses from engine block and water pump.
- 7Remove starter and access transmissionFrom underneath vehicle, disconnect starter electrical connections (main power cable and solenoid trigger wire). Remove starter mounting bolts and remove starter from bellhousing. This provides access to lower transmission-to-engine bolts and torque converter access cover if equipped with automatic transmission.Torque specMounting Bolts34 Nm (25 lb-ft)
- 8Separate transmission from enginePosition transmission jack under transmission and secure with safety chain. Remove torque converter access cover. Mark torque converter to flexplate relationship, then remove flexplate-to-converter bolts (rotate crankshaft for access to all bolts). Remove all transmission-to-engine bellhousing bolts (typically 6-8 bolts around perimeter). Support transmission weight on jack. Carefully separate transmission from engine by sliding it rearward, ensuring torque converter remains with transmission.⚠Transmission weight is approximately 200 lbs. Ensure jack is properly positioned and rated for the load.Torque specTransmission-to-Engine Bolts55 Nm (41 lb-ft)Flywheel Bolts95 Nm (70 lb-ft)
- 9Remove engine mount fastenersSupport engine weight with hoist attached to factory lifting eyes (one at front, one at rear of engine). Take up slack but do not lift engine yet. Remove engine mount-to-frame bolts on both sides. Then remove engine mount-to-block bolts on both sides. Inspect engine mounts for damage and replace if necessary during reinstallation.Torque specEngine Mount-to-Frame Bolts75 Nm (55 lb-ft)Engine Mount-to-Block Bolts65 Nm (48 lb-ft)
- 10Final disconnections and verificationPerform final walk-around inspection to verify all hoses, wires, cables, and brackets are disconnected from engine. Check that nothing remains attached that could be damaged during removal. Verify hoist chains are secure and engine leveler is properly adjusted. Double-check transmission jack is supporting transmission securely.
- 11Remove engine from vehicleSlowly raise engine with hoist while using engine leveler to maintain proper angle. Tilt engine slightly front-up to clear radiator support area. Continue lifting while guiding engine forward to clear transmission. As engine clears engine bay, adjust leveler to keep engine balanced. Once clear of vehicle, lower onto engine stand or suitable support. Install engine stand mounting bolts to rear of block where transmission mated.⚠️Never position any body part under suspended engine. Clear all personnel from area during lift.
Reassembly
- Clean all mating surfaces thoroughly, especially transmission bellhousing to engine block surface. Replace all gaskets.
- If flywheel/flexplate was removed, ensure it is clean and bolts are new if TTY type. Torque in star pattern as specified.
- Apply anti-seize to exhaust manifold studs before installing nuts. Follow hot-to-cold tightening sequence.
- Verify torque converter is fully seated in transmission before mating engine (should be recessed approximately 1/2 inch from bellhousing face).
- Install new AC compressor O-rings and lubricate with appropriate refrigerant oil before connecting lines.
- Double-check all electrical connectors are properly seated and locked.
- Refill all fluids to proper levels: engine oil (7.5 qt), coolant (16 qt), power steering (1 qt), transmission (11 qt total, may require less initially).
- Bleed cooling system using coolant refill funnel or by running engine with heater on high until thermostat opens and air purges.
- Have AC system evacuated and recharged by certified technician.
- Torque all fasteners to specifications in the order listed during disassembly, working in reverse order.
Verification
- Start engine and verify no leaks from coolant, oil, fuel, power steering, or transmission systems.
- Check for proper oil pressure within 5 seconds of starting (gauge or warning light).
- Verify all dashboard warning lights extinguish after startup (check engine, oil, battery, coolant).
- Allow engine to reach operating temperature and verify cooling fans cycle properly.
- Test drive vehicle and verify smooth acceleration, no unusual noises, and proper transmission operation.
- Recheck all fluid levels after test drive and top off as necessary.
- Inspect under vehicle for any leaks after test drive, particularly at exhaust connections and engine mounts.
- Verify AC system operates properly with no leaks (certified technician should perform leak test).
- Check engine and transmission mount alignment - no excessive vibration at idle or during acceleration.
