Pull the clutch. It may be easier to pull the motor and do this on the bench. Or jack the motor up to get frame clearance to operate the puller. You will see once you get the puller in hand. Most likely you need to get an impact on the puller.
Once the clutch is off, remove timing belt cover & replace belt while timing marks are lined up as shown in the service manual. (this info in the stickies)
Adjust the belt tension & replace the cover. Re install the clutch & adjust the valves .
