Watch this video to learn how to remove and replace the alternator belt on a Smart Fortwo. Lift the car on a column lift and remove the wheel, then use a socket spanner to remove the engine cover (if available).

Use a spanner to loosen the tensioner bolt and slide the belt off the alternator. Use a socket spanner to unscrew the bolt until it is removed from the tensioner.

Fit the new belt with the bolt, tightening everything with the spanner. Finally, fit the securing bolts of the splash guard and refit the wheel with the tyre onto the vehicle.

How to Reset the Tire Pressure Light on a MG ZS?

On the instrument cluster of the MG ZS, the tire pressure light that appears can be reset by inflating the tires to the correct pressure: this value will be indicated on the sticker attached to the driver's door pillar. Once the tires have been properly inflated, you can turn on the instrument cluster and navigate through the menu until you find the option that indicates tire pressure: if this screen shows the new values, the light will turn off; otherwise, you will need to drive for a few miles so that the sensors can read the new values and turn off the light afterward.
