What tools are needed to change the timing belt on a 1991 Toyota Celica?

i would invest in a set of metric sockets and wrenches im thinking 10mm soc. for valve cover,fan 12mm for radiator removel 12mm and 15 i think for timing cover 12mm for water pump 19mm or 22mm for crank shaft pully and a pully a three figer claw type will work if you take your time and use bolt in thread hole so not to ding them up a posy lock is best pull off cover make sure to line up timing marks read at least one if not two sections ahead in a haynes or chiltons gasket scraper i hope i answered your question it has been a couple years since i have done one but pationts and think use common sence and it is a piece of cake
