14.The wire inserted at the auto-tensioner installation is pulled
out and then the special tool MD998738 is removed by
hand.
15.Give two clockwise turns to the crankshaft. Wait for 15
minutes, then proceed with the following inspection steps.
16.Check to see whether the metal wire (inserted when the
auto-tensioner was installed) can be removed without any
resistance.
If the metal wire can be removed without any resistance, it
means that the belt has a proper tension. Therefore, remove
the metal wire. In this condition, check that the rod
protrusion of the auto-tensioner is within the standard value.
Standard value: 3.8
− 4.5 mm (0.15 − 0.17 inch)
17.If the metal wire offers resistance when removed, repeat the
previous steps 10 through 15 until the standard value is
obtained as measured by the rod projection of the
auto-tensioner rod.

TIMING BELT
Replace the belt if any of the following conditions exist:
1. Hardening of rubber backing.
Back side should be glossy without resilience and leave no

6. Abnormal wear of belt sides. Normal wear is indicated if the
sides are sharp as if cut by a knife. Abnormal wear is
indicated if the sides are ragged.
7. Abnormal wear on teeth.
Initial stage:
Canvas worn (fluffy canvas fibers, rubbery texture
gone, white discoloration, canvas texture indistinct)
Final stage:
Canvas worn, exposing rubber (tooth width reduced)
8. Missing tooth.

AUTO-TENSIONER
1. Check for oil leaks. If oil leaks are evident, replace the
auto-tensioner.
2. Check the rod end for wear or damage and replace the
auto-tensioner if necessary.
3. Measure the rod protrusion. If it is out of specification,
replace the auto tensioner.
Standard value: 12 mm (0.5 inch)
4. Press the rod with a force of 98 to 196 N (22 to 44 pound)
and measure the movement of the rod.
If the measured value is out of the standard value, replace
the auto-tensioner.
Standard value: 1.0 mm (0.03 inch) or less

VALVE CLEARANCE ADJUSTMENT
Adjust the valve clearance as follows:
CAUTION
Rotate the crankshaft clockwise at any time.
1. Rotate crankshaft clockwise and then align the timing mark
on the camshaft sprocket with the timing mark on the rocker
cover. (Place No.1 cylinder on the top dead center of
compression stroke.)
2. Remove the rocker cover.
3. Measure the valve clearances marked with arrows shown in
the figure.
A: When No.1 cylinder is on the top dead center of
compression stroke.
B: When No.4 cylinder is on the top dead center of
compression stroke.
4. Using a thickness gauge, adjust the clearance between the
valve shaft end and the adjusting screw.
Standard value (in cold state):
<Vehicles for CALIFORNIA emission>
Intake side: 0.11 mm (0.004 inch)
Exhaust side: 0.21 mm (0.008 inch)
<Vehicles for except CALIFORNIA emission>
Intake side: 0.11 mm (0.004 inch)
Exhaust side: 0.22 mm (0.009 inch)
NOTE: After the engine assembly is installed on the vehicle,
check the valve clearance again with the engine warmed up.
Adjust if necessary.
5. Hold the adjusting screw with a screw driver so it does not
rotate then tighten the lock nut.
6. Rotate the crankshaft one time clockwise and then align the
timing mark with the timing mark on the crankshaft sprocket.
(Place No.4 cylinder on the top dead center of compression
stroke.)
7. Adjust the valve clearance for the rest of the valves.
8. Install the rocker cover.
