The problem is your mechanic.
Nobody could really figure out where the noise is coming from without listening to it themselves though, so you're gonna hafta do a little homework and inspect it yourself before your quackanic makes u pay to change more random parts.
Is it a metal-on-metal scraping noise? Is it belt squeal? Do you hear it at standstill as well or only when the car is moving? Are your engine oil and transmission fluid at proper levels?
If you only hear it when the car is moving, have someone inspect your brakes and wheel bearings.
Look for a wobbly pulley or tensioner, or any shield that may have come loose and is touching any rotating parts. Look for scarring/scrapes/scuffs near any rotating parts.
You can also listen out for the noise. The old school guys used to use a stethoscope or piece of hose to listen to specific areas on the engine for noises.
Determine if the noise is coming from the inside or outside of the engine. Listen around near the alternator or a/c compressor (still re-check the tensioner for good measure) in case it's a worn bearing causing it.
Don't be afraid to go poking around the engine bay. Doing the groundwork yourself can prevent you from getting a 6 for a 9. You already paid for a new tensioner that didn't solve your problem.
