Question about 1993 Oldsmobile Cutlass Supreme

My son's 93 supreme is overheating within a few mins of driving. I think we should first change the thermostat, then is there a sensor that we should look at as well?

A thermostat is always a good thing to replace as it is relatively in-expensive, however, I would be checking to see if the cooling fan is coming on. Typically, you should have the cooling fan coming on between 100 - 108 degrees celsius. If you don't have cooling fan operation, I would check for power to it (12 volts at cooling fan motor harness). Let me know what you find!

GOOD MORNING! SINCERELY I VERY MUCH APPRECIATE YOUR AUTOMOBILE KNOWLEDGE YOU ARE ABLE TO OFFER US! MY 20 y-o Son, ANDREW HAS A YOUNG MAN HE WORKS AT SONIC WITH WHO IS COAXING HIM TO BUY THIS 1993...


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.

Ran a 300 mile trip up to Pennsylvania mountains this weekend. 2001 Jeep Grand Cherokee ran fine. I did notice though that while driving with ac on I got a blast of hot air. Temp gauge was at 200 to 210 no...


Doesn't sound as though you have overheating issues.
With a 196 thermostat, a vehicle is designed to run at 200 to 210,and you were putting it under a load on your trip.
I don't know why you would think about changing anything,unless you were doing some trouble shooting, and a test you were performing, indicated a failed component.
I would change the thermostat, as preventative maintainance every five years, and watch for the fans to be working after a trip of five miles or so.
Your A/C may have been switched off, by the various computer systems, to prevent overheating, or it may be starting to have it's own issues.

Overheated I think it's the thermostat


If it was me, I would flush the radiator, and change out the thermostat. Those are the first things I would look at.

Start with the cheapest part and that would be the thermostat. They are easy to replace and that appears to be the issue. They do wear out or stick.

93 olds cutlas supreme overheating but there is no steam. Where is the fan temperature sensor located?


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.

Overheating and Heat doesn't work


Sounds to me like air trapped somewhere in the coolant's path. You said there's a warm spot on top of the engine. This makes me think of possibly a cracked intake manifold or cylinder head. Did it overheat right before this started? I would have the coolant system 'back flushed' and if the problem is still there, I'd next do a compression test (with the radiator cap off).and check to see if there are air bubbles in the radiator while testing. Good luck, please let me know what you find.
