Gearbox — Checking the level and changing the oil (Opel Zafira A)

We check the oil level in the gearbox during vehicle maintenance in accordance with the maintenance regulations (see "Periodic maintenance"), and also if there is a suspicion of oil leakage from the gearbox (see "Manual gearbox - technical condition check"). We carry out the check with the engine off after parking for at least 15 minutes. The gearbox uses oil with a viscosity of SAE 80W (for operation at particularly low temperatures - 75W). The volume of oil in the gearbox is 1.8 l.

The manufacturer does not provide for changing the oil in the gearbox during operation. However, the need to drain the oil and then replace it may arise, for example, when removing the gearbox for repair (see "Manual gearbox - technical condition check").

To perform the work, you will need an inspection pit or overpass, a special syringe for pouring oil into the gearbox (see "Tools, accessories and operating materials").

Checking the level

1. Prepare the car for work (see "Preparing the car for maintenance and repair").

2. Using a 13 mm wrench, unscrew the inspection hole plug.



3. The oil should reach the bottom edge of the hole. If this is not the case, oil must be added.



4. To do this, unscrew the reversing light switch (see "Reverse Light Switch - Checking and Replacing").

5. Using an oil syringe, add oil to the gearbox until it overflows the edge of the inspection hole.



6. Screw in the inspection hole plug.

Recommendation: Do not apply excessive force to tighten the plug. To prevent oil leaks, it is better to apply sealant to the threaded part of the plug.

7. Install the reversing light switch.

Replacement

1. Place a container under the differential cover to drain the oil.

2. Loosen the ten bolts securing the differential cover.



3. Drain the oil from the gearbox without removing the cover.



4. Finally, unscrew the mounting bolts and remove the cover.



5. Drain the remaining oil from the lid.

Recommendation: Before filling with new oil (for example, after repairing a gearbox) replace the differential cover gasket. If necessary, cut off the old gasket with a sharp knife.

6. Install the cover and tighten the mounting bolts to a torque of 18 Nm.

7. Fill with oil (see above, "Checking the level").
