The system does ask for that information. Click this link to pull up a picture.
Did you not see any of that?
If it has just 1 belt it will have a tensioner pulley on it.
EDIT - There is no clock running. And there are no time limits here. Tomorrow is fine if you would like to continue once you have more information.

Hello. Mt name is***** try something different to eliminate all the accessories on the front of the engine. Remove the water pump belt does the noise go away? If no remove the alternator belt does noise go away? The water pump belt is the first belt then alternator behind that one.
