4. Apply the liquid gasket using suitable tool without breaks to the
specified location.
• If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
• As for the bolt holes, normally apply the liquid gasket inside the holes. If specified, it should be applied outside the holes.
Make sure to read the text of this manual.
• Within five minutes of the liquid gasket application, install the
mating component.
• If the liquid gasket protrudes, wipe it off immediately.
• Do not retighten after the installation.
• After 30 minutes or more have passed from the installation, fill the engine with the specified oil and coolant. Refer to MA-11,
"FOR USA AND CANADA : Fluids and Lubricants".
CAUTION:
If there are more specific instruct ions in the procedures contained in this manual concerning liquid
gasket application, observe them.

INSPECTION AFTER INSTALLATION
• 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-11, "FOR USA AND CANADA : 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 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 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.
