7.
Disconnect ground from the No. 3 terminal. The actu-
ator rod should return. lf it does not return, but the
vent hose and filter are not plugged, the solenoid
valve assembly is defective.
Repeat steps 2 through 5. and disconnect ground
from the No. l terminal. The actuator rod should
return. lf it does not return, but the vent hose and
filter are not plugged, the solenoid valve assembly
is defective.
lf you replace the solenoid valve assembly, be sure
to use new O-rings on each solenoid.
Disconnect power and ground from the 4P connector.
Disconnect the vent hose from the actuator. Connect
a vacuum pump to the actuator vent hose port, and
apply vacuum. The actuator rod should pull in com-pletely. lf not, the vacuum valve is stuck open.
Replace the actuator,

lf necessary, disconnect the cable end from the link-

Actuator Cable Adiustment
'1.Check that the actuator cable operates smoothly
with no binding or sticking.
Start the engine. Hold the engine at 3,000 rpm with
no load (A,/T in E or E position, M/T in neutral)
until the radiator fan comes on, then let it idle.
Measure the amount of movement of the actuator
rod until ths cable pulls on the accelerator lever
(engine speed starts to increase). Free play should
be 11 t 1.0 mm (0.43 i 0.04 in).
LOCKNUT FREE PLAY: 11 t 1.0 mm
10.43 r 0.04 in)
lf free play is not within specs, loosen the locknut,
and turn the adjusting nut as requirsd,
NOTE: lf necessary, check the throttl€ cable frso
play (s€e section 11), then recheck the actuator rod
free play.
Retighten the locknut, and recheck the free play.

Adjust the shift cable (see section l4).. Adjust the throttle cable (see section 11).. Refill the engine with engine oil (see page g-4).
. Refill the transmission with oil or fluid (see sec-tion 13 or 14).
. Refill the radiator with engine coolant (see page
10_5).
. Bleed air from the cooling system with theheater valve open (see page l0-5).. Clean the battery posts and cable terminals withsandpaper, assemble them, then apply grease toDrevent corrosron.. Inspect for fuel leakage (see section 1l).After assembling fuel line pans, turn on the igni-tion switch (do not operate the starter) so thatthe fuel pump operates for approximately twoseconds and the fuel Iine pressurizes.
Repeat this operation two or three times, andcheck for fuel leakage at any point in the fuel line.
