Good morning fellow Tsikoteers!

I just want to ask what are the symptoms if you should already change your timing belt? Others said that it's based on the mileage of the car (70T to 80T kms) but the thing is, I'm not sure whether my odometer is tampered or not.

So far I don't hear any noises and the acceleration is still smooth. I just want to make sure that everything's ok to prevent future damages.

Hope you can help me with this..
