In the process of removing the engine, you will come across a number of steps
which call for the removal of a separate component or system, such as "disconnect
the exhaust system'' or "remove the radiator.'' In most instances, a detailed
removal procedure can be found elsewhere in this manual.
It is virtually impossible to list each individual wire and hose which must
be disconnected, simply because so many different model and engine combinations
have been manufactured. Careful observation and common sense are the best possible
approaches to any repair procedure.
Removal and installation of the engine can be made easier if you follow these
basic points:
- If you have to drain any of the fluids, use a suitable container.
- Always tag any wires or hoses and, if possible, the components they came
from before disconnecting them.
- Because there are so many bolts and fasteners involved, store and label
the retainers from components separately in muffin pans, jars or coffee cans.
This will prevent confusion during installation.
- After unbolting the transmission or transaxle, always make sure it is properly
supported.
- If it is necessary to disconnect the air conditioning system, have this
service performed by a qualified technician using a recovery/recycling station.
If the system does not have to be disconnected, unbolt the compressor and
set it aside.
- When unbolting the engine mounts, always make sure the engine is properly
supported. When removing the engine, make sure that any lifting devices are
properly attached to the engine. It is recommended that if your engine is
supplied with lifting hooks, your lifting apparatus be attached to them.
- Lift the engine from its compartment slowly, checking that no hoses, wires
or other components are still connected.
- After the engine is clear of the compartment, place it on an engine stand
or workbench.
- After the engine has been removed, you can perform a partial or full teardown
of the engine using the procedures outlined in this manual.
- Relieve the fuel system pressure on fuel injected models. Disconnect the
negative battery cable first, the positive battery cable second, then remove
the battery from the vehicle.
- Mark the position of the hood on the hinges and remove the hood.
- Raise and safely support the vehicle. Drain the engine oil and coolant.
Remove the splash shields, as necessary.
- Remove the starter and the transmission.
- Disconnect the exhaust system from the exhaust manifold.
- Remove the converter inspection cover and disconnect the converter from
the flywheel.
- Remove the converter housing-to-engine block bolts and the adapter plate-to-converter
housing bolt. Lower the vehicle.
- Remove the air cleaner assembly, if carburetor equipped. Disconnect the
accelerator cable.
- Remove the cooling fan and the radiator shroud. Disconnect the radiator
hoses and transmission oil cooler lines, if equipped, and remove the radiator.
- Disconnect the fuel lines, heater hoses and brake vacuum hose.
- Tag and disconnect the necessary electrical connectors and vacuum hoses.
Remove the ground wires from the cylinder block.
- If carburetor equipped, disconnect the secondary air pipe assembly. On 1989–93
2.6L engine, remove the resonance chamber.
- Remove the accessory drive belt(s). Remove the alternator and mounting bracket,
then position the alternator aside.
- If equipped, remove the power steering pump pulley and the power steering
pump. Position the pump aside, leaving the hoses connected.
- If equipped, remove the air conditioning compressor and position aside,
leaving the hoses attached.
- Remove the gusset plates, if equipped. Remove the transmission oil cooler
line retainers, if equipped.
- If necessary, remove the radiator grille. Remove the shroud upper plate
and the additional condenser fan, if equipped.
- Position a jack under the transmission and install suitable engine lifting
equipment to the engine. Remove the engine mount nuts and raise the engine
slightly, then carefully pull it from the transmission. Carefully lift the
engine out of the engine compartment.
- Install the engine on a workstand.
To install:
NOTE: Lightly oil all bolts and stud threads, except those
specifying special sealant, prior to installation.
- Using the hoist or engine crane, slowly and carefully position the engine
in the vehicle. Make sure the exhaust manifolds are properly aligned with
the exhaust pipes.
- Align the engine to the transmission and install two engine-to-transmission
bolts.
NOTE: Seat the left-hand side, front engine mount insulator
locating pin prior to the right-hand side, front engine mount insulator.
- Lower the engine onto the front engine mount insulators.
- Detach the engine crane or hoist from the engine.
- Remove the floor jack from beneath the transmission.
- Tighten the two installed engine-to-transmission bolts, then raise and securely
support the vehicle on jackstands.
- Install and tighten the remaining engine-to-transmission bolts.
- The remainder of installation is the reverse of the removal procedure. Be
sure to tighten the fasteners to the values presented in the torque specification
chart.
WARNING
Do NOT start the engine without first filling it with the proper type and
amount of clean engine oil, and installing a new oil filter. Otherwise,
severe engine damage will result.
- Fill the crankcase with the proper type and quantity of engine oil. If necessary,
adjust the transmission and/or throttle linkage.
- Check to make sure that all electrical wiring harnesses, linkages, ground
wires, hoses, vacuum and fuel lines have been properly connected.
- Check to make sure that all adjustments have been performed, as well as
all fasteners tightened properly.
- Install the air intake duct assembly.
- Install the battery into the vehicle. Connect the positive battery cable
first, then connect the negative battery cable.
- Fill and bleed the cooling system.
- Start the engine and allow it to reach normal operating temperature, then
check for leaks and proper operation.
- Stop the engine and check all fluid levels.
- Install the hood, aligning the marks that were made during removal.
- If equipped, have the A/C system properly leak-tested, evacuated and charged
by a MVAC-trained, EPA-certified, automotive technician.
