-- [ Picked text/plain from multipart/alternative ] I think my son's '93 90S V6 has a stuck thermostat. Can he replace it himself (he has never so much as changed a plug) or is it a significant job as on the 5 cyl? For future reference, could you give us the name(s) of a capable, inexpensive (Ha!)service tech in the Aurora-Joliet, IL area? Thanks H. Reed Doughty
