10. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.

Using a feeler gauge, measure the clearance be-
tween the valve lifter and the camshaft.

Record the out-of-specification valve clearance
measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake
0.15 - 0.25 mm (0.006 - 0.010 in.)
Exhaust
0.25 - 0.35 mm (0.010 - 0.014 in.)
(b) Turn the crankshaft 1 revolution (360°) and align the mark
as above (See procedure in step 9).
(c) Check only the valves indicated as shown. Measure the
valve clearance. (See procedure in step (a))
11. ADJUST VALVE CLEARANCE
(a) Remove the timing belt (See page EM-15).
(b) Remove the camshafts (See page EM-35).
(c) Remove the valve lifter and adjusting shim.
(d) Determine the replacement adjusting shim size according
to the following Formula and Charts:

Using a micrometer, measure the thickness of the
removed shim.

Calculate the thickness of a new shim so that the
valve clearance comes within the specified value.
T ........... Thickness of removed shim
A ........... Measured valve clearance
N ........... Thickness of new shim

Intake:
N = T + (A - 0.20 mm (0.008 in.))
Exhaust:
N = T + (A - 0.30 mm (0.012 in.))

Select a new shim with the closest thickness as
close as possible to the calculated value.
HINT:
Shims are available in 41 increments of 0.020 mm (0.0008 in.),
from 2.00 mm (0.0787 in.) to 2.80 mm (0.1102 in.).
(e) Place a new adjusting shim on the valve.
(f) Place the valve lifter.
(g) Reinstall the camshafts (See page EM-57).
(h) Reinstall the timing belt (See page EM-22).
(i) Recheck the valve clearance.
12. REINSTALL CYLINDER HEAD COVERS
13. REINSTALL IGNITION COILS
14. REINSTALL NO.3 TIMING BELT COVERS (See page
EM-22)
15. REINSTALL AIR CLEANER AND INTAKE AIR CON-
NECTOR ASSEMBLY
16. REFILL WITH ENGINE COOLANT
17. START ENGINE AND CHECK FOR LEAKS
18. RECHECK ENGINE COOLANT LEVEL
19. REINSTALL V-BANK COVER
20. REINSTALL BATTERY CLAMP COVER

3 HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles by
dividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the power
source is received from the battery as far as each ground point. (All circuit
diagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuit
where the problem was detected (see System Circuit section), the power source
supplying power to that circuit (see Power Source section), and the ground points
(see Ground Point section). See the System Outline to understand the circuit
operation.
When the circuit operation is understood, begin troubleshooting of the problem
circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing
sections to find each part, junction block and wiring harness connectors, wiring
harness and wiring harness connectors, splice points, and ground points of each
system circuit. Internal wiring for each junction block is also provided for better
understanding of connection within a junction block.
Wiring related to each system is indicated in each system circuit by arrows
(from__, to__). When overall connections are required, see the Overall Electrical
Wiring Diagram at the end of this manual.
