To recover the reduction of engine performance, the intake valve timing and the amount of lift of the intake
and exhaust valves have been changed from those of the base 5S-FE engine.

Intake and Exhaust Valves
To improve their wear resistance, the intake valves have undergone special heat treatment, and the mate-
rial of the exhaust vavles has been changed.
The shape of the stem to which the keepers attach has been changed to accommodate the adoption of the
cam with a high lift and of the inner shim type valve adjusting shims.
Valve Lifter and Adjusting Shims
TiN (titanium nitride) coated valve lifter is used to reduce the friction.
To accommodate the high lift, inner shim type valve adjusting shims are used.
Valve Spring
The valve springs for both the intake and exhaust sides accommodate the adoption of the cam with a high
lift and of the inner shim type valve adjusting shims. In addition, their spring rate has been optimized to
reduce friction.

Drive belt tension:
w/ A/C
New belt
175 + 5 lbf
Used belt

w/o A/C
New belt
125 + 25 lbf
Used belt

HINT:
wªNew beltº refers to a belt which has been used
less than 5 minutes on a running engine.
wªUsed beltº refers to a belt which has been used
on a running engine for 5 minutes or more.
wAfter installing a belt, check that it fits properly in
the ribbed grooves.
wCheck with your hand to confirm that the belt has
not slipped out of the groove on the bottom of
the pulley.
wAfter installing a new belt, run the engine for
about 5 minutes and recheck the belt tension.
VALVE CLEARANCE INSPECTION AND
ADJUSTMENT
HINT: Inspect and adjust the valve clearance when
the engine is cold.
1. DISCONNECT HIGH ± TENSION CORDS FROM
SPARK PLUGS
Disconnect the high ± tension cords at the rubber
boot. DO NOT pull on the cords.
NOTICE: Pulling on or bending the cords may damage the
conductor inside.
2. REMOVE CYLINDER HEAD COVER
(a) Disconnect the PCV hoses.
(b) Loosen the 2 wire harness clamp bolts (No.2 timing
belt cover) mounting bolts.
(c) Remove the 4 nuts, grommets, head cover and gasket.
± 5S±FE ENGINEENGINE MECHANICALEG1±12

4. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
Using a thickness gauge, measure the clearance
between the valve lifter and camshaft.
Record the out± of ±specification valve clear±
ance measurements. They will be used later to
determine the required replacement adjusting
shim.
Valve clearance (Cold):
Intake
0.19 ± 0.29 mm (0.007 ± 0.011 in.)
Exhaust
0.28 ± 0.38 mm (0.011 ± 0.015 in.) 3. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley and align its groove with
timing mark ª0º of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 cylinder are
loose and valve lifters on the No.4 are tight.
If not, turn the crankshaft one revolution (360*) and
align the mark as above.
(b) Turn the crankshaft one revolution (360
) and align
the mark as above. (See procedure in step 3)
(c) Check only the valves indicated as shown. Measure
the valve clearance. (See procedure in step (a)) HINT: Arrange the grommets in correct order, so that
they can be reinstalled into their original positions.
This minimizes any possibility of oil leakage due to
reuse of grommets.

(c) Install the gasket to the head cover.
(d) Install the head cover with the 4 grommets and nuts.
Uniformly tighten the nuts in several passes.
Torque: 23 N±m (230 kgf±cm. 17 ft±lbf)
HINT: Install the grommets so that their markings are
as shown in the illustration.
(e) Tighten the 2 wire harness clamp (No.2 timing belt
cover) mounting bolts.
(f) Connect the PCV hoses.
7. RECONNECT HIGH±TENSION CORDS TO SPARK
PLUGS(c) Install a new adjusting shim.
wPlace a new adjusting shim on the valve lifter.
wUsing SST (A), press down the valve lifter and
remove SST (B).
SST 09248±50020 (09248±05011, 09248±05021)
(d) Recheck the valve clearance.
6. REINSTALL CYLINDER HEAD COVER
(a) Remove any old packing (FIPG) material.
(b) Apply seal packing to the cylinder head as shown in
the illustration.
