The 4AFE is a non-interference engine. Whenever you do the belt there are several things you should do at the same time(if you want to do it right and avoid having to go back into it). If you want to patch it disregard my advice.
1. You will need a valve-cover gasket and the three hold-down grommets. Make sure you remove the aluminum half-moon seal at the front of the engine and re-seal with rtv.
2.You will need a camshaft seal and a front crank seal. They are easy to replace and no doubt will be hard & seeping oil.
3. If the tensioner for the t-belt is noisey at all replace it while you are in there.
4. The w-pumps on the 4AFE engines would last many miles. If there is any weeping from the weep hole on the pump I would go ahead and change it while you are there. They are not that expensive. The undisputed best quality pump is the Aisin pump . It was OE equipment on these cars. It came with the front & rear housing and the o-rings you will need.
5. Buy a top-quality t-belt from someone like NAPA or Carquest. There are low-ball junk belts out there that are not made from HSN rubber. They won't last 50K miles.
6. Go ahead and replace the accessory drive belts while you are there. There are three:1. P/S belt,2.Alt. belt,3. A/C belt
Latly, the t-belts on the 4AFE will not jast as long as the Honda belts. The 4AFE used a flat-cogged belt that was thinner and less durable. Honda made theirs much stouter because they had longer reccommended service intervals and they were valve-benders. The older Corollas were the best econobox ever made. Well serviced ones will run 400,000 miles with little more than fluids,filters,belts. If I had to make my living just waiting on them to die I would starve to death.

Old style square toothed timing belts do not last as long as the modern rounded toothed versions.
80k is a good long life for an old style one. Plus, it is almost 20 years old!
Gather parts and do this before it bites you at an inopportune time.

This current belt has been in since 54k miles so it's 60k miles and 4-5 years time wise. I'll change it next year when I do the shock/strut, which will be performance part. That's 3 months from now.
