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).

With engine running, visually observe grooves in pulleys (not pulley flanges) for excessive wobble. Replace
components as required. Check all accessories, mounting brackets and drive belt tensioner, for any interference
that would prevent component from mounting properly. Correct any interference conditions and recheck belt
tracking. Tighten all accessories, mounting brackets and drive belt tensioner retaining hardware to specification.
Replace drive belt is excessive cracking or wear, severe glazing or frayed cords are present. Minor cracks in
back of drive belt are considered acceptable.
