Hey, when i turn on my car and when i have my foot on the accelerator something in my engine makes a cricket sound. (and no it is not a real cricket). I just changed all my belts solving the squeaking from them but the sound still remains. I am hoping someone can help me.

It's probably the alternator, power steering pump, or the water pump.

To find the location, stick a length of rubber hose in your ear, and probe around with the other end. You should at least be able to hear where it's coming from.

another thing that makes that sound is the timing belt tensioner pulley. The bearing in that pulley wears out at 70,000+ miles. if you have not replaced the timing belt and tension pulley, and the car has more than 70,000 miles, do it.

I have 75000km. You should replace it around 100,000km. 70000 miles is probably somewhere near 100,000km but maybe i should go take a look at it anyway

I think that 100,000 is pushing it too far. The engine will still run, but the pulley starts to get noisy around 70,000, the bearing starts to wear out at that point. I think it's a really good idea to change it early, and avoid the risks that go along with a worn timing belt and tensioner, even if it's not really "worn out." Perhaps I'm just paranoid, or I love quiet engines. (probably both)...My timing pulley broke when I was pulling out of my driveway, at about 94,000 miles, and I just pushed it back in the garage and tore it down. No valve damage thankfully...but if I was going 65 MPH on the freeway!!! And at 94,000 the tensioner pulley bearing was practically destroyed, I mean wiped out. That my friend was a lucky save, in the right place at the right time.
And you know, I never drive the car hard, just take it really easy at low RPM.

OK so take the alternator belt off, power steering belt off, etc...and run it parked, see if the noise goes away. You can find out if it's an outside problem or an "under the timing cover" problem.

But overall, Hyundai is still the most trouble free car I ever owned, and I can't fault the design, it's really pretty good for the price you pay. You know, even the most expensive cars have problems...

Il give it a try later today. 100,000km is about 62,000 miles but i will still check it out.

I also have another little problem that maybe you can help me with (i made a post for it also). When i release the brake pedal i can hear my drums squeak. Same thing happens when i release the handbrake. Any ideas as to what it is?

At 62,000 the odds are that the pulley is OK. But if you take the outside belts off and still hear the noise...there may be something amiss under the timing cover for sure.
I think I replied to that post. There are really a couple things, one is that where the shoe metal contacts the brake mounting back plate, there are actually a few lubrication points, where the metal part of the brake shoe is moving against the plate, and that is supposed to be cleaned and lubed with a very small amount of grease. There are also a few moving parts like the brake cable that are supposed to be cleaned and lubricated.
Then there is just the dust from the shoe contacting the drum which sometimes causes a noise. Depends on how the drum surface condition is, and the material the shoe is made out of...there are better materials now days...metal ceramic shoes instead of asbestos, which cost a lot more but are quieter and last longer, more temperature resistant. And there is actually a drum surface cleaner product which is supposed to cut down the noise.
I did install some ceramic parts about 20,000 miles ago, and so far I don't get that noise. But let's face it, the drum brakes are primitive, like the rear of a VW bug. It's not difficult to take the drum off and clean it, and have a look at the wear. And here in Grover Beach, there's a guy who turns them for $7 each, a bargain for this side of the pond.
