Gear Oil Level Check

The manual transmission, transfer gears, extension case and differentials (front and rear) are lubricated with gear oil. To check the gear oil level in any of the above locations, use the following procedure: 1) Park the vehicle on a level surface. Set parking brake and stop the engine.

2) Remove the oil filler plug (1).

3) Check the inside of the hole with your finger. If the oil level comes up to the bottom of the plug hole, the oil level is correct. If so, reinstall the plug.

4) If the oil level is low, add gear oil through the filler plug hole (1) until the oil level reaches the bottom of the filler hole, then reinstall the plug.

Gear Oil Replacement

To change the gear oil in the manual transmission, transfer case, extension case or differential(s), use the following procedure: 1) Remove the oil filler plug (1).

2) Remove the drain plug (2), drain the oil and reinstall the drain plug.

3) Pour new gear oil of the specified type through the filler hole until the oil level reaches the bottom of the filler hole.

4) Reinstall the filler plug.

After driving the vehicle, gear oil temperature WARNING:
After driving the vehicle, gear oil temperature may be high enough to burn you. Wait until the oil filler plug is cool enough to touch with your bare hands before inspecting or replacing gear oil.

CAUTION:
When tightening these plugs, apply sealing compound “SUZUKI Bond No. 1215” or equivalent to the plug threads to prevent oil leakage and tighten them to the specified torque shown below.
