Reliable Alternator for Vauxhall Vivaro?

I have noticed that my Vauxhall Vivaro's alternator is not functioning as well as it used to. Can anyone suggest a reliable and high-quality alternator replacement for my vehicle?

I have had a similar issue with my Vivaro and I have found that the alternator from Bosch is a good option.

I have always used the alternator from Valeo for my Vivaro and it has never let me down.

Make sure to check the voltage rating of the alternator you choose, as it needs to match the requirements of your vehicle.
