we your thermostat needs changing for sure. and the temp sensor if its saying that should be at between 80-90 fan kicks in at 93. if pipe is popping off would also change the expansion tank cap as well as this is supposed to release pressure on the system.

If I remember right it is on the rear of the 4 cyl. engine. pass side in valve cover completely covered by a black rubber hose.

Do the high beams work? How about he signal lights? seems to me a light relay (fuse) is gonzo. Basically, there is a light switch that is wired to a fuse/relay. From this fuse relay there is another wire that goes towards the headlights. Seeing both lights are not working chances are the fuse /relay is done for. Cheap and easy fix.

check all of your grounds a bad ground or a shorted ground can trigger stuff to go off at random plus if it started right up when you got the car jumped then yea it has to be a bad ground like i said check all of your ground wires and update me with the situation

As I mentioned on another Post. Swap out your Relay and see if the problem moves to another system. If not, sounds like your Fan Motor is not working and needs to be replaced.You said that if you TAP on it, then it will go SLOW....

If the Fan is working after you tap on it, that is telling me that the Motor is shot. If the RELAY is not working, that will cause it also.Most of these Fans have a 2 Speed Motor, This is controlled by the RELAY, If it was my car, I would sway out a relay (there are multiple in the Fuse Box and see if it makes a difference.Pay attention where you swap it out. If it is the RElay, you are going to have the problem moved to another System

Go to e-bay and type in either or both of the alternators, and after searching a few of those offered for sale, you will see a list of all the different cars and models they fit. At accordingly.Be blessed.
