OIL PRESSURE CHECK
1. CHECK ENGINE OIL QUALITYCheck the oil for deterioration, presence of water, discoloring
or thinning.
If the quality is poor, replace the oil.
Oil grade: API grade SG, Energy±Conserving II multigrade.
Recommended viscosity is as shown, with SAE 5W±30 being
the preferred engine oil.
2. CHECK ENGINE OIL LEVELThe oil level should be between the ºLº and ºFº marks on the
dipstick.
If low, check for the leakage and add oil up to ºFº mark.
3. REMOVE ENGINE UNDER COVER
4. REMOVE DRIVE BELT Loosen the drive belt tension by turning the drive belt tension-
er clockwise, and remove the drive belt.
5. DISCONNECT A/C COMPRESSOR WITHOUT DISCONNECTING HOSES
(a) Disconnect the compressor connector.
(b) Remove the four mounting bolts and nut.
(c) R e m o v e t h e t h r ought bolt, and disconnect the
compressor from the engine.
HINT: Put aside the compressor, and suspend it.
6. REMOVE OIL PRESSURE SWITCH, AND INSTALL OIL PRESSURE GAUGE
(a) Disconnect the oil pressure switch connector.
(b) Using SST, remove the oil pressure switch.SST 09816±30010
(c) Install an oil pressure gauge.

1. REPLACE TIMING BELT
(a) Remove the timing belt.(See page EG±46)
(b) Install the timing belt. (See page EG±59)
2. INSPECT DRIVE BELT HINT: A belt tensioner is used, so checking the belt tension
is not necessary.
(a) Visually check the drive belt for excessive wear, frayed cords,
etc.
If necessary, replace the drive belt.
HINT:
w Cracks on the rib side of a drive belt are considered
acceptable. If the drive belt has chunks missing from the
ribs, it should be replaced.
w The drive belt tension can be released by turning the
belt tensioner counterclockwise. The pulley bolt for the
belt tensioner has a left±hand thread.
(b) Check the belt tensioner operation. wCheck that the belt tensioner moves downward when
the drive belt is pressed down at the points indicated in
the illustration with approx. 98 N (10 kgf, 22.0 lbf) of
force.
w Check the ali gnment of the belt tensioner pulley to make
sure the drive belt will not slip off the pulley.
If necessary, replace the belt tensioner.
w Check that the arrow mark on the belt tensioner falls
within area A of the scale.
If it is outside area A, replace the drive belt.
HINT:
w When a new belt is installed, it should lie within area B.
If not, the drive belt is not correct.
