TIMING CHAIN

Do not overtighten slack guide bolts. It is normal for a gap
to exist under the bolt seats when bolts are tightened to
specification.

• When installing timing chain tensioner (primary), push in plunger and keep it pressed in with stopper pin.
• Remove any dirt and foreign materials completely from the back and the mounting surfaces of timing

chain tensioner (primary).

• After installation, pull out stopper pin.

7.

Make sure again that the mating marks on camshaft sprockets and timing chain have not slipped out of
alignment.

8.

Install front timing chain case. Refer to 

EM-164, "Removal and Installation"

.

INSPECTION AFTER INSTALLATION

• Before starting the engine, check oil/fluid levels including engine coolant and engine oil. If the levels are

lower than required quantity, fill to the specified level. Refer to 

MA-16, "For North America: Fluids and Lubri-

cants"

.

• Run engine to check for unusual noise and vibration.

NOTE:
If hydraulic pressure inside timing chain tensioner drops 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 leakage of fuel, exhaust gas, or any oil/fluids including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down the engine, again check oil/fluid levels including engine oil and engine coolant. Refill to

specified level if necessary.

• Summary of the inspection items:

* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
