NOTE: The procedure for pulling the engine requires removing
the transaxle along with it. As a result, when the halfshafts are pulled from
the transaxle, a special plug/side gear holding tool is recommended.
- Before servicing the vehicle, refer to the precautions in the beginning
of this section.
- Properly relieve the fuel system pressure.
- Drain the engine oil.
- Drain the transaxle fluid.
- Drain the cooling system.
- Remove or disconnect the following:
- Battery cables and battery
- Battery tray

- Hood
- Front wheels
- Splash shield(s) from under the vehicle
- Air cleaner assembly and resonance chamber, including the air flow meter
and all of the ducting
- Oil dipstick
- On the Millenia with the 2.3L engine, remove the charge air cooler, front
grille, upper seal board (panels that the grille mounts to) and coolant overflow
tank.
- Remove or disconnect the following:
- Radiator hoses
- Transmission oil cooler lines from the radiator, if equipped with automatic
transaxle
- Cooling fan and radiator switch electrical connectors
- Radiator/cooling fan assembly
- Throttle and speedometer cables

- Shift control cable, if equipped with automatic transaxle
- Tie rod ends from the steering knuckles
- Stabilizer bar from the lower control arms
- Attach an engine lifting chain to the engine lifting eyes. Attach the chain
to a suitable engine hoist and raise the hoist until there is tension on the
chain.
- Remove or disconnect the following:
- Engine mount member
- Lower ball joint from the steering knuckle
- Bolts from the right side intermediate shaft support, if equipped
- Intermediate shaft by prying it from the transaxle
- Suspend the halfshafts with wire.
- Remove or disconnect the following:
- Dynamic damper from the right side engine mount, if equipped.
- Engine/transaxle mount nuts/bolts and right engine (if equipped) and
left transaxle mounts
- Lift the engine/transaxle assembly from the vehicle.
- Remove or disconnect the following:
- Intake manifold bracket
- Starter
- Torque converter nuts
- Engine-to-transaxle stiffener, if equipped
- No. 2 engine mount
- Throttle valve cable

To install:
- Installation is the reverse of the removal procedure. Note the following
important steps.
- When possible, leave the engine mounting nuts/bolts loose (hand tight) until
all mounts are aligned and bolted. This may help in aligning the engine and
transmission assembly in the vehicle.
- Install new circlips on the inner CV-joint stub shafts, if equipped, and
the intermediate shaft. Grease the shaft splines before installing the halfshaft/intermediate
shaft into the transaxle.
- Always install new gaskets and/or O-rings. Use new self-locking nuts, especially
on the exhaust.
- Fill the engine and the transaxle with oil. Fill the cooling system.
- Connect the negative battery cable, start the engine and check for leaks.
- Check the ignition timing and the idle speed.
- Check all fluid levels.
- Before servicing the vehicle, refer to the precautions in the beginning
of this section.
- Properly relieve the fuel system pressure.
- Drain the engine oil.
- Drain the cooling system.
- Remove or disconnect the following:
- Negative battery cable
- Fresh air duct and the air cleaner/air flow meter assembly
- Transmission
- Accelerator cable from the throttle body
- Undercover
- Radiator hoses and the coolant reservoir hose
- Cooling fan electrical connector
- Transmission oil cooler hose, if equipped with automatic transmission
- Radiator/cooling fan assembly
- Accessory drive belts
- Power steering pump and move it aside without disconnecting the hydraulic
hoses
- Air conditioner compressor and move it aside without disconnecting the
refrigerant lines
- Disconnect the following electrical connectors:
- Steering pressure sensor electrical connector
- Throttle position sensor electrical connector
