I have heard mixed comments so I really would like to know and I don't overheat my car while driving on the City. It has never reached the red but it has gotten very closed. My car has 80k miles and everything is original on it. Does anybody know where i can get a maintenance book so I know what parts I need to replace or what preventive maintenance I can do to my car at 80K?
Thanks in advance.

Sounds like the oil cooling fan isn't working at all or maybe only works on low speed.
There are several possible causes, most likely the fan itself but also the fan resister is a known weak link.
It's fairly easy to change these parts out if you are mechanically inclined, otherwise take it to a reputable shop.
