Default cheen-cheen-cheen noise when pressing accelerator

A friend of mine has this problem, which I have noticed to be quite common among taxis in Delhi. This problem is in an 8 year old Zen.

When you start the car there's a cheen-cheen-cheen sound when you press the accelerator. The sound goes after a couple of minutes of driving. But it is very loud.

I know this is something very common so I hope someone here can tell me EXACTLY what it is, and whether it needs to be rectified soon, and how much it would cost to do so.

The belts have become hard or loose

Yes. The sound comes as soon as you start the car. And it makes that noise when you press the accelerator at neutral+standstill or ingear+moving. But the sound goes away after a few minutes of driving. Then even if you stop at a red light and press the accelerator in neutral it doesn't make the noise.

So the alternator belt requires changing or just greasing? Either way what's the cost? (Will get it done from local repairwallahs, not A.S.S.)

I agree with karan, its the belt, apply grease on the top part (not the inner layer).

Before applying grease, please check for belt slack and try adjusting slack if any.

Grease is a very makeshift and temporary solution.
Bees wax is what most belt conditioners are made up of.

The car is celebrating China's olympic success. It will calm down soon enough.

I think this calls for drive belt replacement. I think there was another thread which discussed the same a while back. Till you get them replaced I think grease should do the trick.

Ok, neither my friend nor I are very engine savvy. I don't think I would be able to locate the belt. So will just get it replaced.

Would a local repairwallah be safe, or is this an important part that only the A.S.S. guys should change? How much would it cost?

Veb, any local chap should be able to do it. It is not a critical job.
I don't know the cost, but it would be small (couple of hundred at most). Do buy a good, branded belt.
