INSPECTION
1. INSPECT WATER PUMP
(a) Visually check the drain hole for coolant leakage.
If leakage is found, replace the water pump.
(b) Turn the pulley, and check that the water pump bearing
moves smoothly and quietly.
If necessary, replace the water pump.
2. INSPECT TIMING BELT COMPONENTS

VALVE CLEARANCE
INSPECTION
HINT:
Inspect and adjust the valve clearance when the engine is cold.
1. REMOVE CYLINDER HEAD COVER
(a) Disconnect the 4 high±tension cords from the clamps on
the cylinder head cover.
(b) Disconnect the 4 high±tension cords from the spark
plugs.
(c) Disconnect the PCV hose from the intake manifold.
(d) Disconnect the PCV hose from the cylinder head cover.
(e) Disconnect the engine wire clamp from the mounting bolt
of the No.2 timing belt cover.
(f) Remove the cylinder head cover. (See page EM±33)
2. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with timing
mark º0º 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.
3. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.
(2) Record the out±of±specification valve clearance
measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake0.19 ± 0.29 mm (0.007 ± 0.011 in.)
Exhaust0.28 ± 0.38 mm (0.011 ± 0.015 in.)
(b) Turn the crankshaft one revolution (360°) and align the
mark as above.

(3) Select a new shim with a thickness as close as pos-
sible to the calculated value.
HINT:
Shims are available in 17 sizes in increments of 0.05 mm
(0.0020 in.), from 2.50 mm (0.0984 in.) to 3.30 mm (0.1299 in.).
(c) Install a new adjusting shim.
(1) Place a new adjusting shim on the valve lifter.
(2) Using SST (A), press down the valve lifter and re-
move SST (B).
SST 09248±55040 (09248±05410, 09248±05420)
(d) Recheck the valve clearance.
5. REINSTALL CYLINDER HEAD COVER
(a) Install the cylinder head cover. (See page EM±53)
(b) Connect the PCV hose to the intake manifold.
(c) Connect the PCV hose to the cylinder head cover.
(d) Install the engine wire clamp to the mounting bolt of the
No.2 timing belt cover.
(e) Install the 4 high±tension cords to the clamps on the cylin-
der head cover.
(f) Connect the 4 high±tension cords to the spark plugs.
