• Do not allow the coolant to
contact the drive belts.
• Perform this step when engine is cold.
5. When draining all of the coolant in the system for engine removal or repair, open all of the drain plugs (A-D) on the cylin-
der block.
6. Check the drained coolant for contaminants such as rust, corro- sion or discoloration.
If the coolant is contaminated, flush the engine cooling system.
REFILLING ENGINE COOLANT
1. Install the radiator drain plug. If the cooling syst em was drained completely, install the reservoir tank and
the cylinder block drain plugs.
• The radiator must be complete ly empty of coolant and water.
• Apply sealant to the threads of the cylinder block drain plug. Use Genuine High Performance
Thread Sealant or equivalent. Refer to GI-21, "Recommended Chemical Products and Sealants"
.
CAUTION:
Do not reuse copper sealing washers.
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.

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"
.

The ECM receives information such as the injecti
on pulse width and camshaft position sensor (PHASE) sig-
nal. Computing this information, ignition si gnals are transmitted to the power transistor.
During the following conditions, the ignition timing is revi sed by the ECM according to the other data stored in
the ECM.
• At starting
• During warm-up
•At idle
• At low battery voltage
• During acceleration
The knock sensor retard system is designed only for emergencies. The basic ignition timing is programmed
within the anti-knocking zone, if recommended fuel is used under dry conditions. The retard system does not
operate under normal driving conditions. If engine knocking occurs, the knock sensor monitors the condition.
The signal is transmitted to the ECM. The ECM retards the ignition timing to eliminate the knocking condition.

• After removing the bolts and nuts, separate the mating surface and
remove the liquid gasket using Tool (A).
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use a
plastic hammer to slide (2) the cutter by tapping on the side.
CAUTION:
Do not damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the liquid gasket tube to the tube presser. Use Genuine Silicone RTV Seal ant or equivalent. Refer to
GI-21, "Recommended Chemical Products and Sealants"
.
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
