My vette started to overhead while going through a drive-thru. I checked the fluid, OK. So, I changed the thermostat. Still overheating. I changed the water pump and It's still overheating. What's the deal? I have a c5 2003 covette. 5.7L

Do you

Yes! I have gotten it to 253. The car was running great! I already checked out all of the other fluids.
