3. Attach liquid gasket tube to tube presser (SST).
Use Genuine Liquid Gasket or equivalent.
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.

If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.

As for the bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of this manual.

Within 5 minutes of liquid gasket application, install the mating
component.

If liquid gasket protrudes, wipe it off immediately.

Do not retighten mounting bolts or nuts after the installation.

After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe
them.

90 degrees (one marks).
e. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns
smoothly.
13. For the following operations, perform steps in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluid 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-14, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

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 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.
