What was the code the dealership pulled?

Check coolant level. If they did not completely get all the air out of the cooling system it will cause the issue you are having.

You may be getting a false reading from the gauge due to the new sensor. Make sure they installed a Delco sensor. Aftermarket sensors are troublesome. HTH. -Jim

Thanks for the input .Took it to another mechanic changed the sensor light again ,temp gauge returned to normal..However check engine light still on ..He told me it's either the computer chip or the cluster..Good thing is car is not overheating .. It's an old car don't know if it's worth the cost of replacing these items as they are just faulty lights..Other wise car is in excellent shape interior and exterior.

You're welcome. Glad to help. Since your Olds is a '95 model it's OBD I. If your mechanic doesn't have a scan tool that will pull the trouble code(s) you can do it with a large paperclip. You'll need to get the two digit trouble code(s) in order to fix the check engine light issue. Glad the temperature gauge is fixed. Thanks for letting us know. If you need help getting those codes using a large paperclip let us know. I'll be glad to walk you through it. Your mechanic may know how to do it as well if he's an older person. HTH. -Jim
