18. Remove the timing chain tensioner (primary) as follows:
a. Pull the lever (C) down to release the plunger stopper tab (B).
b. Insert the stopper pin A into the tensioner body hole to hold the lever (C) and keep the plunger stopper tab (B) released.
NOTE:
An allen wrench [(1.2 mm (0.047 in)] is used for a stopper pin A
as an example.
c. Compress the plunger (D) into the tensioner body (1) by press- ing the slack guide (2).
d. Keep the slack guide (2) pressed and lock the plunger (D) in by pushing the stopper pin A through the lever (C) and into the
chain tensioner body hole.
e. Remove timing chain tensioner bolts and then remove the timing chain tensioner. CAUTION:
Be careful not to drop timing chain te nsioner bolts inside timing chain case.
19. Remove the three water pump bolts (A). Make a gap between water pump sprocket (1) and timing chain, by carefully turning

4. Turn the crankshaft pulley approximately 20
° clockwise so that
the timing chain on the timing chain tensioner side is loose.
5. Apply engine oil to the oil feed hole and timing chain tensioner and install the timing chain tensioner.
6. Remove the stopper pin (A).
7. Install valve timing control cover (bank 1) and water pump cover.
a. Before installing, remove all traces of liquid gasket from mating surface of water pump cover and IVT cover using a scraper.
Also remove traces of liquid gasket from the mating surface of the front cover.
b. Apply a continuous bead of liquid gasket to mating surface of IVT cover and water pump cover. Use Gen-
uine RTV Silicone Sealant or equivalent. Refer to GI-21, "Recommended Chemical Products and
Sealants".
CAUTION:
• Installation should be done within 5 minutes afte r applying liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after the co mponents are installed to allow
the sealant to cure.
8. Install water drain plug (A) and copper sealing washer (B). CAUTION:
Do not reuse copper sealing washers.
9. Installation of remaining components is in the reverse order of removal. • After installation, refill coolant and check for leaks. Refer to CO-36, "Changing Engine Coolant"
and CO-
35, "System Inspection".
CAUTION:
Do not spill coolant in en gine compartment. Use a sh op cloth to absorb coolant.
• After starting engine, let idle for three minutes, then rev engine up to 3,000 rpm under no load to purge air from the high-pressure chamber of the chai n tensioner. The engine may produce a rattling noise.
This indicates that air still remains in the chamber and is not a matter of concern.
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"
.
