Why does my Vauxhall Astra make a screeching noise when I start the engine?

Whenever I start my Vauxhall Astra, there is a loud screeching noise that lasts for a few seconds. It doesn't happen all the time, but it's starting to worry me. Is this a common issue and what can I do to fix it?

The screeching noise could be caused by a loose or worn out belt. I recommend taking your car to a mechanic to have the belt checked and replaced if necessary.

It could also be a problem with the starter or alternator. I suggest getting it checked by a professional to avoid any further damage.

Make sure to check your oil levels, as low oil can also cause a screeching noise. If the oil levels are fine, I suggest having a mechanic inspect the engine for any other potential issues.
