I recently had my timing belt replaced. On cold starts, the belt seems to be making a chirping/sqeaky sound. It goes away when the car is warmed up though. Is this anything I should be concerned about? Its been 3 months since I had the belt changed and the belt and it still making the chirping sound. It's not loud but you can clearly hear it on cold starts.

Thanks in advance for any input.

Did they just change the belt or use the full kit with new tensioner, wheels etc. Also its recommended that the water pump is changed at the same time. Could be that the belt is a bit too tight which will cause bearings to fail on either the tensioner, pulleys or waterpump. I would get it looked at as it isnt normal for it to be making a noise.
