Engine Removal/Installation
Make sure jacks and safety stands are placed proper-
ly and hoist brackets are attached to the correct
positions on the engine (see section 1).
Make sure the car will not roll off stands and fall
while you are working under it.
3. Remove the expansion tank cap to speed draining.
Use care when removing the expan-
sion tank cap to avoid scalding by hot engine
coolant or steam.
4. Raise the hoist to full height.
5. Drain the engine coolant (see section 10).

drain engine coolant from cylinder heads. Con-
nect rubber hoses to the drain bolts.
6. Drain transmission oil/fluid. Reinstall the drain plug
using a new washer.
CAUTION: Do not overtighten the drain plug.
7. Drain the engine oil. Reinstall the drain plug using a
new washer.
8. Lower the hoist.
9. Remove the strut bar.
CAUTION:
Use front and rear fender covers to avoid damaging
painted surfaces.
Unspecified items are common.
Unplug the wiring connectors carefully while holding
the coupler and the connector portion to avoid
damage.
Mark all wiring and hoses to avoid mis-connection.
Also, be sure that they do not contact other wiring or
hoses or interfere with other parts.
If the ground clearance needs to be increased, use a
scissors jack and install the rubber spacers to the coil
springs (page 1-8).
Put rubber pads under the jacking points when using
jacks or safety stands to avoid damaging the body
(page 1-9 to 11).
