Why is my Ford Transit Custom making a weird sound when I turn on the engine?

I recently purchased a Ford Transit Custom and noticed that whenever I turn on the engine, there's a strange noise coming from the engine bay. It's not too loud, but it's definitely noticeable. I'm not sure what could be causing this and I'm worried it might be a bigger issue.

It's possible that there could be an issue with your exhaust system. I'd recommend taking your Transit Custom to a trusted mechanic to get it checked out.

In my experience, this could be caused by a loose belt in the engine. It's best to get it checked out sooner rather than later to avoid any potential damage to your vehicle.

It might just be a normal sound for the Transit Custom. I'd suggest talking to other Transit Custom owners or bringing it to a Ford dealership to compare the noise with other vehicles.
