A/C ENGINE SYSTEM NOISE, SUGGESTIONS?? Options

[charming6gmoz]

I wanted to ask if anyone had an idea or can guide me of how to find out
the problem in my car with a rattleling noise in the engine whenever I turn the A/C.

And it only happens whenever I turn the AC on.

If I turn off the A/C the noise goes away.

But if I turn it back on the noise comes back,
it sounds like the engine is working double or something.

Please if any ideas or suggestions. Please let me know.
I would appreciate.

Thank you.

My Celica has 330,000 and it still runs like a charm.

Never had problems with noises like the one is doing now.

You're so right. It has to be the A/C pulley belt, because that's
what it souns like, like if there is a belt loose, I just didin't know the
A/C has one.
Is it easy to replace?
