< REMOVAL AND INSTALLATION >
ENGINE ASSEMBLY
a. Before removing the drive plate, put a match mark (A) on thecrankshaft and drive plate for alignment during installation.
b. Remove the drive plate. • Holding the crankshaft pulley bolt, lock the crankshaft to remove the drive plate bolts.
• Loosen the bolts diagonally.
CAUTION:
• Be careful not to damage the drive plate. Especiallyavoid deforming and damaging of the signal plate teeth
(circumference position).
• Place the drive plate with th e signal plate surface facing
other than downward.
• Keep magnetic materials away from the signal plate.
CAUTION:
Use an engine stand that has a load capacity [a pproximately 240kg (529 lb) or more] large enough
for supporting the engine weight.
• If the load capacity of the stand is not adeq uate, remove the following parts beforehand to
reduce the potential risk of overturning the stand.
- Remove the fuel tube and fuel injector assembly. Refer to EM-40, "
Removal and Installation".
- Remove the intake manifold. Refer to EM-26, "
Removal and Installation".
- Remove the ignition coil. Refer to EM-37, "
Removal and Installation".
- Remove the rocker cover. Refer to EM-38, "
Removal and Installation".
- Other removable brackets.
CAUTION:
Before removing the hanging chains, make sure th e engine stand is stable and there is no risk of
overturning.
31. Remove the generator. Refer to CHG-22, "
Removal and Installation".
32. Remove the engine mounting insulator and bracket using power tool.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• When replacing an engine or transmission you mu st make sure the dowels are installed correctly
during re-assembly.
• Improper alignment caused by mi ssing dowels may cause vibration, oil leaks or breakage of driv-
etrain components.
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-12, "
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.

4. Install the Tool by installing the radiator cap adapter onto theradiator neck opening. Then attach the gauge body assembly
with the refill tube and the venturi assembly to the radiator cap
adapter.
5. Insert the refill hose into the coolant mixture container that is placed at floor level. Make sure the ball valve is in the closed
position.
• Use Genuine NISSAN Long Life Anti-freeze coolant or equiva-
lent, mixed 50/50 with distilled water or demineralized water.
Refer to MA-12, "
Engine Oil Recommendation" .
6. Install an air hose to the venturi assembly, the air pressure must be within specification.
CAUTION:
The compressed air supply must be equipped with an air
dryer.
7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open the ball valve on the refill hose slightly. Coolant will be vi sible rising in the refill hose. Once the refill hose is
full of coolant, close the ball valve. This will purge any air trapped in the refill hose.
8. Continue to draw the vacuum until the gauge reaches 28 inches of vacuum. The gauge may not reach 28 inches in high altitude
locations, refer to the vacuum specifications based on the alti-
tude above sea level.
9. When the vacuum gauge has reached the specifi ed amount, disconnect the air hose and wait 20 seconds
to see if the system loses any vacuum. If the vacuum level drops, perform any necessary repairs to the
system and repeat steps 6 - 8 to bring the vacuum to the specified amount. Recheck for any leaks.
10. Place the coolant container (with the refill hose insert ed) at the same level as the top of the radiator. Then
open the ball valve on the refill hose so the coolant will be drawn up to fill the cooling system. The cooling
system is full when the vacuum gauge reads zero.
CAUTION:
Do not allow the coolant container to get too low when filling, to avoid air from being drawn into
the cooling system.
11. Remove the Tool from the radiator neck opening and install the radiator cap.
12. Remove the non-vented reservoir cap.
13. Fill the cooling system reservoir tank to the specif ied level. Run the engine to warm up the cooling system
and top up the system as necessary before installing the vented reservoir cap.

WARNING:
• Be careful not to burn yourself, as the engine and engine oil are hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct skin
contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as
possible.
1. Warm up the engine, and check for any oil leaks.
2. Stop the engine and wait for at least 10 minutes.
3. Remove the oil drain plug and oil filler cap to drain the old oil.
4. Install a new washer on the oil drain plug, then install the oil drain plug in the oil pan.
CAUTION:
Clean the drain plug and install with a new washer.
5. Refill the engine with new specified engine oil.
CAUTION:
The refill capacity depends on th e oil temperature and drain time. Use the “Refill oil capacity” val-
ues as a reference and check the oil level using th e dipstick when filling the engine with oil.
6. Warm up the engine and check the area around the dr ain plug and oil filter for any oil leaks.
7. Stop the engine and wait for more than 10 minutes.
8. Check the oil level using the dipstick as shown. Add oil as nec- essary and install the oil filler cap.
CAUTION:
Do not overfill the engine with oil.
