1. To remove valve guide, heat cylinder head to 110
° to 130 °C
(230 ° to 266 °F) by soaking in heated oil.
WARNING:
Cylinder head contains heat. When working, wear protective
equipment to avoid getting burned.
2. Drive out the valve guide with a press [under a 20 kN (2.2 US ton) pressure] or hammer and suitable tool.
3. Ream cylinder head valve guide hole.
4. Heat cylinder head to 110 ° to 130 °C (230 ° to 266 °F) by soaking
in heated oil and press new valve guide from camshaft side into
the cylinder head to the dimensions as shown.
WARNING:
Cylinder head contains heat . When working, wear protec-
tive equipment to avo id getting burned.

8. Use a depth gauge to measure the distance between the mount-
ing surface of the cylinder head spring seat and the valve stem
end. If the distance is shorter than specified, repeat step 5 to
adjust it. If it is longer, replace the valve seat with a new one.
VALVE SPRING SQUARENESS
Set try square along the side of valve spring and rotate the spring.
Measure the maximum clearance between the top face of spring and
try square.
VALVE SPRING DIMENSIONS AND VALVE SPRING PRESSURE LOAD
Check valve spring pressure at specified spring height.
If it is not within specif ications, replace the spring.

• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner dr ops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.

Aiming AdjustmentINFOID:0000000009463617
PREPARATION BEFORE ADJUSTING
Before performing aiming adjustment, check the following:
• Ensure all tires are inflated to correct pressure.
• Place vehicle and screen on level surface.
• Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
• Coolant and engine oil filled to correct level, and fuel tank full.
• Remove cargo and/or luggage to maintain an unloaded vehicle condition.
• Confirm spare tire, jack and tools are properly stowed.
• Carefully wipe off any dirt from headlamp lens. CAUTION:
Do not use organic solvent (thinner, gasoline etc.)
• Place a driver or equivalent weight of 68.5 kg (150 lb) on the driver seat.
• By hand, bounce the front and rear of the vehicle to settle the suspension and eliminate any static load.
• Place the front tires in the straight ahead position.
• Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
NOTE:
• For headlamp aiming details, refer to regulations in your area.
• By regulation, no means for horizontal aim adjustment is provided from the factory; only vertical aim is
adjustable.
• Use adjusting screw to perform aiming adjustment.
• Perform headlamp aiming if:
- The vehicle front body has been repaired.
- The front combination lamp has been removed or replaced.
- Any outfitting has been installed.
- The vehicle’s standard load condition has been substantially increased.
Aiming Adjustment procedure
1. Position the screen.
NOTE:
• Stop the vehicle facing the screen.
• Place the screen on a plain road vertically.
2. Face the screen with the vehicle. Maintain 10 m (33 ft) between the headlamp bulb center and the screen.
3. Start the engine. Turn the headlamp (LO) ON.
