1.CHECK FRONT AND REAR AXLE
Make sure there is no excessive looseness in the front and rear axles.
OK or NG
OK >> GO TO 2.
NG >> Check front or rear axle system.
2.CHECK WHEEL SENSOR
Perform following inspection for wheel sensor:
 Sensor mount and damage inspection

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak. Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to GI-44, "
Recommended Chemical Product and Sealant".
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside chain tensioner drops af ter removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.
 Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil and engine coolant.
 Bleed air from lines and hoses of applic able lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.

4. Crank the engine, and then make sure that engine oil comes out
from camshaft bracket (No. 1) oil hole. End crank after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
Engine oil may squirt from in take valve timing control sole-
noid valve installation hole during cranking. Use a shop
cloth to prevent the engine components and the vehicle. Do
not allow engine oil to get on rubber components such as
drive belt or engine mount insulators. Immediately wipe off
any splashed engine oil.
 Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from camshaft bracket (No. 1) oil hole. Refer to LU-4, "
Lubrication Circuit".
5. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT), and then check each oil groove for clogging.
 Clean oil groove if necessary. Refer to LU-4, "
Lubrication Circuit".
6. After inspection, install removed parts.
Inspection for Leaks
The following are procedures for chec king fluids leak, lubricates leak.
 Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-9, "
Fluids and Lubricants".
 Use procedure below to check for fuel leakage.

CAUTION:
Check the tightening angle by using the angle wrench
(SST). Avoid judgment by vi sual inspection without SST.
 Check tightening angle indicated on the angle wrench indica-
tor plate.
f. Turn all cylinder head bolts 90 degrees clockwise again (angle tightening).
4. After installing cylinder head, measure distance between front end faces of cylinder block and cylinder head (left and right
banks).
 If measured value is out of the standard, re-install cylinderhead.
5. Install in the reverse order of removal after this step.
