Warning :
Be careful when replacing a punctured wheel. Perhaps it was pierced by intruders to steal valuables from the car while you were busy replacing it.
1. Open the trunk (it contains everything you need to change the wheel) and remove the trunk floor mat (or lift it up at the rear).
2. Unscrew the latch.
3. Remove the spare wheel holder.
4. Remove the spare wheel from the trunk and place it next to the wheel to be changed.
5. Remove the decorative cap, overcoming the force of its fixing spring.
6. Engage first gear and parking brake. Place a jack under the Astra next to the wheel to be replaced.
Useful advice:
To avoid getting dirty when changing a wheel, wear gloves and overalls, if your car has them.
7. On the opposite side, the car must be fixed by placing wheel chocks under the front and rear wheels so that the raised car cannot move forward or backward.
8. Using a jack, slightly raise the car, but so that the wheel requiring replacement does not come off the road. Use a wheelbrace to loosen the five wheel bolts.
Helpful Hints:
In order to make it easier to unscrew the wheel bolts, you can use your foot instead of your hands, stepping on the handle of the balloon wrench from above. To facilitate the removal of the bolts, we recommend purchasing a special wheel wrench with a telescopic handle. It is convenient to work with a cross-shaped balloon wrench.
9. Jack up the Opel so that the wheel is off the road, then completely unscrew the bolts and remove the wheel.
Warnings:
Try to keep the car as little time as possible in a suspended state with the wheel removed.
Raise the vehicle with a jack only to the height necessary to remove and install the wheel. If working on soft ground, place a thick board under the base of the jack. Do not use bricks for this purpose - they break easily, and the car can fall off the jack, seriously injuring you.
10. Install the spare wheel in place of the removed one, screw in the fixing bolts until they stop, but do not tighten them.
Warning:
When screwing the bolts, make sure that their conical parts are aligned with the conical surfaces of the holes in the wheel disk, otherwise the bolts will loosen during movement, resulting in the loss of the wheel.
11. Lower Opel Astra and finally tighten bolts. Tighten the wheel bolts through one circle. To avoid damage to the wheel disc, do not try to "hold out" the wheel bolts by pressing the wrench handle with your foot.
Helpful Hints:
In order to feel the necessary tightening force for the wheel bolts, use a torque wrench for the first time (tightening torque 110 Nm).
Do not lubricate the threaded part of the mounting bolts - this can lead to self-loosening of the bolts while the vehicle is moving. It is allowed to lubricate the conical part of the bolts with a thin layer of grease.
12. Install the decorative cap.
13. Before you continue driving, be sure to check the air pressure in the tire of the installed wheel and, if necessary, bring it to normal.
Helpful Hints:
The car has tubeless tires. If you do not have enough tire mounting skills, we advise you not to try to do this work yourself. One damage to the sidewall - and you have to buy a new tire or insert a tube. In a hopeless situation, you can use a special first aid kit for repairing tubeless tires without stripping or a tire sealant. They must be used in accordance with the attached instructions. Why is a tubeless tire better than a tubed one? Firstly, a tubeless one “lowers” very slowly during a puncture: you can drive with a nail in the wheel for weeks, pumping up, until it becomes possible to repair it. Secondly, when, with a very significant mileage, steel cord wires begin to protrude from a tubeless tire, it can still be used as a spare wheel.
