Checking Drive BeltsNBS0000D
WARNING:
Be sure to perform this step when engine is stopped.

Make sure that the indicator (C) (notch on fixed side) of drive belt auto-tensioner is within the possible use
range (A).
NOTE:
Check the drive belt auto-tensioner indication when the engine is cold.

When new drive belt is installed, the indicator (C) (notch on fixed side) should be within the range (B) in
the figure.

Visually check entire drive belt for wear, damage or cracks.

If the indicator (C) (notch on fixed side) is out of the possible use range or belts is damaged, replace drive
belt.
Tension AdjustmentNBS0000E
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.

WARNING:

Put a “CAUTION: FLAMMABLE” sign in the workshop.

Be sure to work in a well ventilated area and furnish workshop with a CO2 fire extinguisher.

Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.

To avoid the danger of being scalded, do not drain engine coolant when engine is hot.
1. Remove engine cover with power tool. Refer to EM-17, "
INTAKE MANIFOLD COLLECTOR" .

4. Crank the engine, and then make sure that engine oil comes out
from valve timing control solenoid valve 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 intake 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 valve timing control solenoid valve hole. Refer to LU-4, "
LUBRICATION SYSTEM" .
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 SYSTEM" .
6. After inspection, install removed parts.
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

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
leakage at connection points.
–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 drops after removal/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 leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.

Bleed air from lines and hoses of applicable 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.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
Valve ClearanceNBS0000U
INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.

VALVE GUIDE CLEARANCE
Valve Stem Diameter
Measure diameter of valve stem with micrometer.
Valve Guide Inner Diameter
Measure inner diameter of valve guide with inside micrometer.
Valve Guide Clearance
(Valve guide clearance) = (Valve guide inner diameter) – (Valve stem diameter)

If it exceeds the limit, replace valve and/or valve guide. When valve guide must be replaced, refer to EM-
97, "VALVE GUIDE REPLACEMENT" .
VALVE GUIDE REPLACEMENT
When valve guide is removed, replace with Oversize (Service) [0.2 mm (0.008 in)] valve guide.
1. To remove valve guide, heat cylinder head to 110 to 130°C (230
to 266°F) by soaking in heated oil.
2. Drive out valve guide with a press [under a 20 kN (2 ton, 2.2 US
ton, 2.0 lmp ton) pressure] or hammer and suitable tool.
WARNING:
Cylinder head contains heat. When working, wear protec-
tive equipment to avoid getting burned.Standard
