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.

WARNINGTo 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

WARNINGWhen 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.

  1. After removing the bolts and nuts, separate the mating surface and remove the liquid gasket using Tool (A). Tool Number: KV10111100 (J-37228) CAUTION: Be careful not to damage the mating surfaces.
  2. In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use a plastic hammer to slide (2) the cutter by tapping on the side. CAUTION: Do not damage the mating surfaces.

  1. Using suitable tool (A), remove old liquid gasket from liquid gasket application surface and the mating surface. Remove liquid gasket completely from the groove of the liquid gasket application surface, mounting bolts, and bolt holes.
  2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating use) to remove moisture, grease and foreign materials.
  3. Attach liquid gasket tube to the suitable tool. Use Genuine Silicone RTV Sealant, or equivalent. Refer to " «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-675571-S19021012742014120500000) ".
  4. Apply liquid gasket without gaps to the specified location according to the specified dimensions. If there is a groove for liquid gasket application, apply liquid gasket to the groove. As for bolt holes (B), normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes. Check to read the text of this Information. Within five minutes of liquid gasket application, install the mating component. If liquid gasket protrudes, wipe it off immediately. Do not retighten mounting bolts or nuts after the installation. After 30 minutes or more have passed from the installation, fill engine oil and engine coolant. CAUTION: If there are specific instructions in the procedures contained in this information concerning liquid gasket application, observe them.

ENGINE OIL LEVEL

Note. Before starting engine, position the vehicle so that it is level and check the engine oil level. If engine is already started, stop it and allow 10 minutes before checking.

  1. Pull out oil level gauge and wipe it clean.
  2. Insert oil level gauge and check that the engine oil level is within the range (A) as shown below.
  3. If it is out of range, adjust it.

ENGINE OIL APPEARANCE

  1. Check engine oil for white milky appearance or excessive contamination.
  2. If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant. Repair or replace damaged parts.

ENGINE OIL LEAKS

Check for engine oil leaks around the following areas

  1. Oil pan (upper and lower)
  2. Oil pan drain plug
  3. Oil pressure sensor
  4. Oil filter
  5. Oil cooler
  6. Oil level sensor
  7. Engine oil temperature sensor
  8. Intake valve timing control solenoid valve
  9. Exhaust valve timing control solenoid valve
  10. Mating surface between front cover and rocker cover
  11. Mating surface between cylinder block and cylinder head
  12. Mating surface between cylinder head and rocker cover
  13. Crankshaft oil seals (front and rear)
  14. Front cover

ENGINE OIL PRESSURE CHECK

WARNINGBe careful not to burn yourself, as engine oil may be hot. When checking engine oil pressure, shift selector should be in the "P" (Park) or "N" (Neutral) position, and apply parking brake securely.

  1. Check engine oil level.
  2. Disconnect harness connector at oil pressure switch. Remove oil pressure switch using suitable tool and install suitable tools (A/B). CAUTION: Do not drop or shock oil pressure switch.
  3. Start engine and warm it up to normal operating temperature.
  4. Check engine oil pressure with engine running under no-load. NOTE: When engine oil temperature is low, engine oil pressure becomes high. If difference is extreme, check oil passage and oil pump for engine oil leaks. Engine oil pressure: Refer to " «ENGINE OIL PRESSURE»(ref-675583-S01097347742014120500000) ".
  5. After the inspections, install oil pressure switch as follows: Remove old liquid gasket from oil pressure switch and engine. Apply liquid gasket and tighten oil pressure switch to specification. Use Genuine Liquid Gasket or equivalent. Refer to " «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-675571-S19021012742014120500000) ". Tightening torque: Refer to " «EXPLODED VIEW»(ref-675577-S27892382432014120500000) ".
  6. Check engine oil level.
  7. After warming up engine, check that there is no engine oil leaks with the running engine.
