91 camaro rs v6 3.1 114000 miles.Im having a problem with overheating I think it might be because of the fan,it doesnt come on untill its almsot 240 degrees should come on at 200 or 220 I replaced the thermostat the engine coolant temp censor and the relays the fan looks good wondering if its the fan motor or the fan censor,also noticed that the pressure drops a little in the radiator and my voltage is running a little high when I first start driving and it helps if I have the air on to keep it cool but I would much rather fix this properly what do you suggest?

The gauges are not that accurate and when they have a little age they tend to read high.

I would invest in an infrared temp gun ( about $90) and you will be able to read the exact temp.
