Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. Information necessary to service the system safely is included in the SRS AIRBAG and SEAT BELTS article of this Service Information.
| WARNING | To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS AIRBAG . Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Information. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. |
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
| WARNING | When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery and wait at least three minutes before performing any service. |

CHECKING COOLING SYSTEM FOR LEAKS
- To check for leaks, apply pressure to the cooling system using suitable tools (A/B). Testing pressure: Refer to " «RADIATOR»(ref-616716-S36725234022014051900000) ".
| WARNING | Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down and turning it all the way. |
Scheme 23
| CAUTION | Perform this step when the engine is cold. Do not spill engine coolant on drivebelt. Higher test pressure than specified may cause radiator damage. |
Note. If engine coolant decreases, replenish radiator with engine coolant. Refer to " RECOMMENDED FLUIDS AND LUBRICANTS ". If anything is found, repair or replace damaged parts.
Radiator hose
Note. Once hose clamp has been placed into position, place a small amount of glue between the hose and the clamp (A). Insert the radiator hose (1) all the way to the stopper (2) or by 33 mm (1.30 in) (hose without a stopper). For the orientation of the hose clamp pawl, refer to the figure.
| Radiator hose | Hose end | Paint mark | Position of hose clamp (1) |
|---|---|---|---|
| Radiator hose (upper) | Radiator side | Upper | A |
| Engine side | Upper | D | |
| Radiator hose (lower) | Radiator side | Upper | C |
| Engine side | Side | B | |
| CVT fluid cooler hoses | Radiator side | Lower | C |

- The angle (b) created by the hose clamp pawl and the specified line (A) must be within ±30 as shown in the figure below.
- To install hose clamps (1), check that the dimension (A) from the end of the hose clamp on the radiator hose to the hose clamp is within the reference value. Dimension "A": (-3) - (+3) mm [(-0.12) - (+0.12) in]
Cooling Fan
Inspect cooling fan for cracks or unusual bends.
- If anything is found, replace cooling fan.
