Have some squeling coming from front of engine.

2005 SRT6 46k miles.

I suppose it could be a belt or bearing?

Noticed it right after I had to gun it.

Can hear it when in idle as well and changes when reving.

Made me think as well, should I be doing some proactive maintenance with this many years on the vehicle?

I suppose do the items in the owners manual such as spark plugs, coolant, fuel filter, etc. which I guess should have been done every 4 to 5 years according to the manual?
