• When installation directions are specified, install parts according to the directions. Refer to EM-72, "Compo-
nent".
• Prior to installing the upper torque rod, apply a light coat of silicone
lubricant (A) to the washer facing side of the bushing inner tube as
shown.
NOTE:
• Apply silicone lubricant (A) by dabbing the outward facing tube
surface with a sponge or suitable tool.
• Do not apply excess lubricant.
• Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.
• Tighten engine mounting insulator (RH) bolts in the numerical
order shown.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-10
.
• 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.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

TOW TRUCK TOWING
TOW TRUCK TOWING
Tow Truck TowingINFOID:0000000001702452
CAUTION:
• All applicable local laws regarding the towing operation must be obeyed.
• It is necessary to use proper towing equipment to avoid possible damage to the vehicle during tow-
ing operation. Towing is in accordance with Towing Procedure Manual at dealer.
• Always attach safety chains before towing.
• When towing, make sure that the transmission, steering system and power train are in good order. If
any unit is damaged, dollies must be used.
NISSAN recommends that the vehicle be towed with the driving (front) wheels off the ground as illustrated.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH FOUR WHEELS ON GROUND
CAUTION:
Never tow an automatic transaxle model with four wheels on the ground as this may cause serious
and expensive damage to the transaxle.
Vehicle Recovery (Freeing a Stuck Vehicle)INFOID:0000000001702453
• Tow chains or cables must be attached only to the main structural members of the vehicle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or cooling
systems.
• Always pull the cable straight out from the front or rear of the vehicle. Never pull on the vehicle at an angle.
• Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or recovery.
WARNING:
• Do not spin the tires at high speed. This could cause them to explode and result in serious injury.
Parts of the vehicle could also overheat and be damaged.
• Install removable recovery hook securely using wheel nut wrench.

SAE Viscosity NumberINFOID:0000000001704726
NISSAN recommends the use of an energy conserving oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubrica-
tion Standardization and Approval Committee (ILSAC) certification 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.

Anti-freeze Coolant Mixture RatioINFOID:0000000001704727
The engine cooling system is filled at the factory with a high-quality, long life, year-round, anti-freeze coolant
solution. The anti-freeze solution contains rust and corrosion inhibitors. Therefore, additional cooling system
additives are not necessary.
CAUTION:
• When adding or replacing coolant, be sure to use only a Genuine NISSAN Long Life Anti-Freeze
coolant or equivalent with the proper mixture ratio.
• The use of other types of coolant solutions may damage the engine cooling system.
