ENGINE COOLANT
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 recommended coolant or equivalent.
Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubri-
cants".
CAUTION:
Do not use any cooling system additives such as radiator
sealer. Additives may clog th e cooling system and cause
damage to the engine, transm ission and/or cooling system.
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, use the vacuum specifications based on the altitude
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.
12. Fill the cooling system reservoir tank to the specif ied level and install the radiator cap. Run the engine to
warm up the cooling system and t op up the system as necessary.
13. Install the engine under cover. Refer to EXT-17, "Removal and Installation"

NOTE:
The following procedures explain how to disassem ble the engine with the engine stand fastened to the bell
housing. Some steps may be different if using a different type of engine stand.
DISASSEMBLY
1. Remove the engine and transaxle as an assembly from the vehicle, and separate the transaxle from the
engine. Refer to EM-84, "Removal and Installation"
.
2. Remove the drive plate. Hold the crankshaft using Tool (A) and use a suitable tool to remove the bolts.
3. Remove pilot converter using Tool.
4. Remove the rear oil seal. Refer to EM-72, "Removal and Installation of Rear Oil Seal"
.
5. Mount the engine on a suitable engine stand (A). CAUTION:
• Use an engine stand that has a load capacity large
enough for supporting the engine weight [approximately
135 kg (298 lb) or more].
• Before removing the hanging chains, check the engine
stand is stable and there is no risk of overturning.
NOTE:
The figure shows an example of widely used engine stand (A)
that can support mating surface of transaxle with drive plate
removed.
• Remove the following parts if the engine stand load capacity is not adequate, to reduce the potential risk of overturning stand:
- Intake manifold. Refer to EM-30, "Removal and Installation"
.
- Exhaust manifold. Refer to EM-33, "Removal and Installation"
.
- Rocker cover. Refer to EM-45, "Removal and Installation"
.
6. Drain any remaining engine oil and coolant from the engine.
7. Remove the exhaust manifold and three way catalyst assembly. Refer to EM-33, "Removal and Installa-
tion".
8. Remove the intake manifold and fuel tube assembly. Refer to EM-30, "Removal and Installation"
.

*1: For additional information, see “Engine Oil Recommendation”.
*2: As an alternative to this recommended oil, SAE 5W-30 conventional petroleum based oil may be used and meet all specificatio ns
and requirements necessary to maintain the New Vehicle Limited Warranty.
*3: NISSAN recommen ds Genuine NISSAN Ester Oil av ailable at a NISSAN dealer.
*4: Use only Genuine NISSAN CVT Fluid NS -3, using automatic transmission fluid other than Genuine NISSAN CVT Fluid NS-3
will damage the CVT, which is not covered by the NISSAN new vehicle limited warranty.
*5: Use of a power steering fluid other than Genuine NISSAN E-PSF will prevent the power steering system from operating properly.
*6: Available in mainland U. S.A. through a NISSAN dealer.
*7: For additional information, see "Air conditioner specification label".
FOR USA AND CANADA : En gine Oil RecommendationINFOID:0000000009464537
NISSAN recommends the use of an energy conserving o il in order to improve fuel economy. Select only
engine oils that meet the American Petroleum Institut e (API) certification and International Lubricant Standard-
ization and Approval Committee (ILSAC) certificati on and SAE viscosity standard. These oils have the API
certification mark on the front of the container. Oils which do not have the specified quality label should not be
used as they could cause engine damage.
