Hopefully i can help..
The 2.0litre petrol engine (code 3s-fe) is known as an interference engine im afraid - this usually means that valve to piston contact would be likely if the timing belt broke or slipped teeth..The only way to know unless you just remove the head to inspect anyway - before which the engine needs timed back up,upper valave train check by removing the top cover to see if any damage is visable there then a compression test done across the four cylinders - and see what readings you get any low readings or loss of compression on a cylinder or cylinders compared to the rest with good and holding compression - will suggest damage on these low reading cylinders - but thats certainly something to do once you get it timed back up rather than remove the head first is to do a compression test or leakage test and confirm the damage so to speak and then take it from there.. Very rarely do you get away with it and just put another belt on - if valves are damaged then it its just case of new headgasket set when the head is being refitted and or a rebuild of the cylinder head you have or a second hand one from a breakers yard..but as above thats about the way forward on this one..I do hope this helps..If you need to ask anything else or include anything further then just continue before you rate
