SOURCE: 95 CHEVY IMPALA SS RUNNIN HOT
You may want to try checking the fans. I have a 95 ss with the same problem. If you disconnect the MAF and then start the vehicle the electric fans will come on. Try driving it like that. That will atleast narrow down your search. If that makes it run cooler then its most likely a problem with the fans. Either a relay or fan switch. Blown head gaskets will usually result in the coolant and oil mixing. Check your fluids for signs of that. I have also read that the radiator cap not sealing properly can cause the coolant system to lose pressure. This reduces the systems ability to circulate the coolant causing it to run hotter. Thats an easy fix. I have not fixed mine yet. I just havent had time. That should be a good place to start. As far as getting a new engine or head gasket they are both really expensive fixes so try any other way u can to fix it first. Hope this helps.

You should probably replace the temperature sensor first, make sure the car is indeed overheating.
If after replacing the temp sensor, and the problem does exist, then buy a flush kit, and back flush the system, it may be clogged.
