Remove rear seat cushions. Disconnect fuel pump connector. Start engine and allow to stall. After engine stalls,
attempt to restart engine to ensure no residual pressure exists. Turn ignition off and reconnect fuel pump
connector. When disconnecting fuel hoses, cover connection with shop rag to catch fuel leakage. To avoid
excessive cranking after servicing, prime fuel system before starting engine.
Priming System
Ensure fuel system is closed. Connect jumper wire between F/P and GND terminals of data link connector. See
Fig. 1
. Turn ignition on for about 10 seconds and check for fuel leaks. Turn ignition off and disconnect jumper
wire.

COOLING SYSTEM BLEEDING
1. Slowly pour coolant into radiator at a rate of 1.1 qt. (1.0L) per minute maximum until coolant is level
with filler port. Fill coolant reservoir to "F" mark. Securely install radiator cap. Start engine.
2. Operate engine at idle until normal operating temperature is reached. If coolant level warning light
illuminates during warm-up, turn engine off and check drain plug and coolant hoses for leaks. Operate
engine at 2200-2800 RPM for 5 minutes. Stop engine and allow to cool.
3. Repeat steps 1) and 2). Check coolant level. If engine coolant is not level with filler neck, repeat entire
procedure. If engine coolant is level with filler neck, fill reservoir to "F" mark.
CAUTION: If engine overheats during procedure, system contains excessive air. Stop
engine and allow it to cool, then repeat step 1).

vehicle. Disconnect exhaust manifold down pipe and exhaust brackets from engine. On A/T models,
remove shift control cable.
6. On M/T models, remove shift control linkage and extension bar. Remove clutch release cylinder and fluid
line bracket from transaxle housing, leaving fluid line connected to cylinder. Secure cylinder away from
transaxle.
7. On all models, remove transmission wiring harness connectors and speedometer cable. Remove axle shaft
nuts from hubs. Disconnect stabilizer bar from lower control arms. Separate lower ball joints and steering
tie-rod ends from steering knuckles.
8. Pry axle shafts out of transaxle. Remove and discard circlip from axle shafts. For further information on
axle shafts, see appropriate article in DRIVE AXLES.
9. Remove transaxle mount nuts from crossmember and loosen crossmember bolts. See Fig. 6
. Lower
vehicle and attach engine hoist for engine removal. Remove engine front mount and transaxle top mount
from inner fender panels. Remove transaxle crossmember. Remove engine and transaxle assembly from
top of vehicle.
10. To install, reverse removal procedure. Tighten bolts and nuts to specifications. See TORQUE
