What I need to do the services for the 80000 miles TOYOTA van?

Answer 1

you may be able to find this in your service manual, some new vehicles come with a service manual that tells you what is needed at every 10,000 mile intervals. If your car didnt come with one, consult with the dealer's service department. That would be the best place for your answer.

Answer 2

everything you can think of from a to z perferably a certified shop but if you are doing it at home get a manual from the library or parts store and do it all from front to back but dont drop gas tank without experianced person around to help very dangerous in fact if in tank pump is working fine leave it alone
