We are having an overheating issue on my buddy's Cutlass. He was driving it last week and the temp light came on. The motor felt hotter than usual too. We changed out the thermostat and it didn't fix it. He changed out the temp sensor and the light was still on. We decided to try the water pump, that seemed to cool the motor slightly but the light stayed on. Last thing we changed was the fan clutch which didn't fix the issue either. Only part we can think of next would be the radiator. He did mention that he hit a bird earlier in the day hours before the light came on but we didn't see anything when we removed stuff for the water pump. Any ideas on what could possibly be causing the issue? The crate motor doesn't have but around 60K on in the last 20 years.
