Overheating 94 saturn sc

I have a 94sc with the vac routing sticker in the engine comp. It's a Massachusettes car that I brought into CA and it passed smog!
I could take a pic of it and send it. I also have the 94sc electrical and vacuum troubleshooting manual.

bad news about those little engines is that the heads are not serviceable if overheated

you may have seized the engine

start by pulling the spark plugs and see if you can turn the engine over

how about the coolant temp sensor, they had alot of problems with that sensor and also the plug for it,some have two of these sensors side by side, one for the gauge and the other for the fan, i would replace these first and go from ther good luck,

There is an air pocket in your cooling system.

Please look up my FIX HERE.

Be very careful as overheating can cause permanent damage to the head gasket.Now whenever an engine temp reaches half then the fan should start,so watch if this is working.Allow engine to run and watch the temp gauge goes up..Once it is half then the fan should start, if it does not replace thermostat..Else watch the radiator as it may be blocked.

yes the choke is not working right,,,
just do as your doing,, hold down the pedal,, its cheeper that getting it fixed,,,and you try and nick it?

best to find out why the check engine light came on first could be you need to find out how that fan runs factory and check every thing out. could have a clogged radiator or a bad t-stat

did u use oem thermostat or at local auto parts? if oem u ok,did put back the plug on temp sensor?did u burp the water line after you change thermostat?

sound like your theromstat if bad of your fan relay may be on there way out

Hello donezero,

Thank you for choosing fixya.com.

Try replacing the thermostat first. I see you mentioned that it overheats with the A/C on, while in neiborhood streets (or lower speeds). Also, with the vehicle parked, and the car running, raise the hood, and watch to see if the fans are coming on. If not, check the fuses in the fuse box. You may have a blown fuse. Examine both top and bottom radiator hoses to make sure there are no cracks, holes, or bubbles. If they look like they need replaced, replace them. Also, check the fuse and any relays that may be associated to the A/C pump - there should be one of each. By changing the thermostat, you eliminating it right away for being the reason of overheating. After diong all this, and the car still overheats under these circumstances, replace the temperature sensor, which is located on the intake manifol (usually close by the thermostat ) driver side of engine, toward front or center. (may be on passenger side, depending on engine). If this does not take care of the problem, consider a certified mechanic for further assistance.

I sincerely hope this information is helpful in getting your car (A/C) running properly. Let me know if I can be of further assistance in this matter. Thank you again for choosing fixya.com.
