Engine Whines when Cold

[Diagro]

hey

Each time i start my engine there is a loud whine from the engine that increases when i rev it.

After a few mins (when engine is up to temp) the sound is gone and its fine.

I had the Belts, Dephaser and waterpump replaced 3 weeks ago.

Any idea? As if its something in that area then the garage will have to sort it. I don't want anything going wrong tbh.

Normal they all do it

Mine did until the belts, adjuster pulleys and dephaser were done, pretty quiet now

Hmm ok.
Didn't notice it till today tbh haha

Mine does this also, was more noticeable before I got belts etc changed but it's still there.
