Try a 160 degree, my car was doing the same thing, overheating like crazy, I replaced literally everything in the cooling system, 3 core radiator etc. Ended up being because I didnt have a thermostat in there and there was a HUGE air pocket in there. Cooling system was being too efficient and circulating the air before it could cool it down. I know this is a stupid question but is the fan blade on maybe backwards on the fan clutch?
After I put the thermostat in mine and bled it, no more over heating. You can also grab a digital temp gun from harbor freight for about 30$.
