ReliGving
Before disconnecting tuel pipes or hoses, release pres-
sure from the system by loosening the 12 mm banjo
bolt on top of the fuel filter.
@o Do not smoke whilo working on the fuel sy3lom.
Ksgp op€n flames or sparks away tlom Your work
arga.
. Be sure to relieve fuel pressule while the ignition
swhch is off.
1. Write down the frequencies for the radio's preset
buttons,
2. Disconnect the battery negative cable from the bat-
tery negative terminal.
3. Remove the fuel fill cap.
Use a box end wrench on the 12 mm banjo bolt at
the fuel filter while holding the fuel filter with anoth-
er wrench.
Place a rag or shop towel over the 12 mm banio bolt.
Slowly loosen the 12 mm banjo bolt one complete
turn.

NOTE: Replace all the washers whenever the 12
mm banio bolt is loosened or removed.
Inspaqtion
1. Relieve fuel pressure.
2. Remove the 12 mm banjo bolt from the fuel filter
while holding the fuel Jilter with another wrench
Attach the special tools.
3. Start the enginethe fuel Pressure with the
engine idling and the vacuum hose of the fuel pres-
sure regulator disconnected from the fuel pressure
regulator and pinched lfthe engine will not start, turn
the ignition switch ON {ll), wait for two seconds, turn
it off, then back on again and read the fuel pressure'

lf the fuel pressure is not as specified, first check the
fuel pump (see page 11-236) lfthetuel pumpisoK,
check tho following:
. lf the fuel pressure is higher than specified,
inspect for:- Pinched or clogged fuel return hose or line.
- Faulty fuel pressure regulator (see page 11-
2341.
. lf the fuel pressure is lower than specified, inspect
for:- Clogged fuel filter.
- Faulty fuel pressure regulator (see page l1-
2341.- Fuel line leakage.

Adjustment
Detlection Method
'1. Apply a force of 98 N (10 kgf, 22 lbf), and measure
the deflection between the A,/C compressor and the
crankshaft PulleY
A/C ComPressor Belt
Used Belt: 816A2 engine
6.0 - 9.5 mm 10 2'l - 0.37 inl
Except 816A2 engine
7.5 - 9.5 mm (0.30 - 0.37 in)

Except 815A2 engine
5.0-5 5 mm (0.20-0.26 inl
Note these items when adjusting belt tens'on:
. lf there are cracks or any damage evident on the
belt, replace it with a new one.
. "Used belt" means a belt which has been used
for five minutes or more.
. "New belt" means a belt which has been used
tor less than five minutes.
2. Loosen, the center nut ofthe idler pulley (SANDEN), or
the pivot bolt of the idler pulley bracket and the lock
nut ofthe adjusting bolt (DENSO).
3. Turn the adjusting bolt to get proper belt tension'
4. Retighten the center nut of the idler pulley (SANDEN),
or the pivot bolt of the idler pulley bracket and the lock
nut of the adjusting bolt (DENSO).
5. Recheck the deflection of the A,/C compressor belt'
Tension Gauge Method
1. Attach the special tool to the IVC compressor belt as
shown below, and measure the tension of the belt
