with the heater valve open (see page 10-5).
a Adjust the th.ottle cable (see section 1 1).
a Check the clutch pedal tree play lsee section 12).
a Check that the transmission shifts into gear
smoothlv,
a Adiust the tension of the following drive belts.
Alternator belt {s€e section 23).
P/S pump belt {see section 17).
A/C comoressor belt (see section 22).
a Inspect tor fuel leakage (see section 1 1).
. After assembling fuel line parts, turn on the ig-
nition switch (do not operate th€ starter) so
that the Juel pump operates for approximat€-
lV two seconds and the tuel line pressurizes.
Repeat this operation two or three times and
check for fuel leakage at any point in the fuel
line.
