ENGINE COOLANT
5. Remove the reservoir tank to drain the engine coolant, then clean the reservoir tank before installing it.
6. Check the drained coolant for contaminants such as rust, corrosion or discoloration.
If the coolant is contaminated, flus h the engine cooling system. Refer to CO-11, "
Changing Engine Cool-
ant".
REFILLING ENGINE COOLANT
1. Close the radiator drain plug. Install the reservoir t ank, cylinder block drain plug, and the oil cooler hose, if
removed for a total system drain or for engine removal or repair.
• The radiator must be completely empty of coolant and water.
• Apply sealant to the threads of the cylinder bl ock drain plug. Use Genuine High Performance Thread
Sealant or equivalent. Refer to GI-15, "
Recommended Chemical Products and Sealants".
2. 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.
3. Remove the vented reservoir cap and replace it with a non-vented reservoir cap before filling the cooling
system.
4. Install the Tool by installing the radiator cap adapter onto the radiator 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-13, "
Fluids and Lubricants".
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.

< REMOVAL AND INSTALLATION >
ENGINE ASSEMBLY
• Before and during lifting, always check if any harnesses are left connected.
33. Remove the parts that may restrict installation of the engine to the engine stand. NOTE:
This procedure is described assuming that you use an engine stand mounting to the surface to which the
transmission mounts.
a. Before removing the drive plate, put a match mark (A) on the crankshaft 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.
34. Remove the generator, if necessary. Refer to CHG-21, "
Removal and Installation".
35. Remove the engine mounting insulator and bracket using power tool, if necessary.
INSTALLATION
Installation is in the reverse order of removal.
