oil pump water pump thermosta, blown head gasket ,leak in hoses

Usually near the thermostat.
By the way, remove the thermostat and drive around with the car. If it still overheats, might have some other problem, like you said, temp sensor, or some kind of electrical problem.

heater core is shot most of them are located under the dash board, look to make sure or call a garage they can tell u were its at

• This heater core is one of the easier ones to service. It is still on the passenger side but is removed from under the glove box. See diagram for a visual. If they were only all so easy....

• You still have to lower the coolant and pull the heater hoses off the tips of the heater core from the engine bay side of the firewall.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

For a number of reasons, I'd stay away from it-it is not going to be great on gas, if it currently has no cam sensor, how can you determine if it runs properly? Although 136,000 miles is not a lot for a 93, if it has not been taken care of (oil changes, tuneups, trans maintanence, etc.) it wil just be a money pit. At the very least, the car should be running, and inspected (which would necessitate replacing the missing muffler). Ask that the car be inspected after the muffler and cam sensor are repaired by a mechanic of your choice, that should probably open your son's eyes to the condition of the vehicle, good or bad. I have a lot of experience with cars, and buying a 'beater' or project car is always a gamble, especially if it does not run. A car that does not run is generally worth scrap only, so $550 it too high.

I dont know what a TIGHT brake pedal is, but if its hard to push and hard, then the brake booster is bad, OR the hose to the booster is bad OR the engine has a bad vacuum leak.

sounds like it jumped time, the timing belt probably lost a tooth off the belt

I dont have an answer for you but i do have this story. i had a similar car same make and model i was always having problems with the ignition system, then i started to have problems with the electrical system. i spent thousands of dollars over 9 months and the problem was never fixed and no one could find or tell me what the problem was for sure. everything was a guess and it still caust me.

you have a mass airflow that prob. neews to be cleaned you can do this in sec. where you airfilter is you will see a according hose going over with a clamp at the end of it, undo the clamp pull the hose back and us mass air flow sensor cleaner( but any parts store for aboutr 10.00) and spray the screan in their and wait for about 3 mins for it to dry befor you reclamp the hose on. see if this works

Remove turn signal assembly (uses a torx 15 driver). This will expose the two 10mm bolts on the one side of the headlight assembly. Remove the plastic front grill (uses a torx 15 driver - there are about 6 screws). This will expose the other two 10mm bolts on the headlight assembly. Remove the four 10mm bolts to remove the headlight assembly and this will allow you access to the headlight you need to replace.
