2001 SUZUKI GRAND VITARA engine oil

7F-4 DIFFERENTIAL (REAR)
Precaution for Maintenance Service
•When having driven through water, check immediately if
water has entered (if so, oil is cloudy). Water mixed oil must
be changed at once.
•Whenever vehicle is hoisted for any other service work than
oil change, also be sure to check for oil leakage and status of
breather hoses.
Differential Gear Oil Change
1) Before oil change or inspection, be sure to stop engine and
lift up vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found,
correct its cause.
3) Drain old oil and pour proper amount of gear oil as specified
(roughly up to level hole).
4) Torque drain plug (3) and level/filler plugs (2) to specification.
“A” : Sealant 99000-31110
Tightening torque
Differential oil level/filler plug (a) :
50 N·m (5.0 kg-m, 36.5 lb-ft)
Differential oil drain plug (b) :
28 N·m (2.8 kg-m, 20.5 lb-ft)
Hypoid gear oil :
API GL-5, SAE 75W-85, 80W-90 or 90
Oil capacity :
2.5 liters (5.3/4.4 US/Imp. pt.) NOTE:
Hypoid gear oil must be used for differential.
It is highly recommended to use SAE 80W-90 viscosity.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual
mentioned in the FOREWORD of this manual.
