Timing Belt every 90k miles so within the next 5k miles at the absolute latest.Preferably yesterday. Get a full kit that includes belt, tensioner, water pump, and the 2 bearings. Change the coolant also (as you're draining most of the coolant out of the block anyway). Takes Toyota Pink/Aisin ACT002
Also the kit you'll want is: AISIN TKT026
