doridoridori

so recently got my car up and running, bled the coolant and everything and sitting in the car at idle it will hang around 180-185F. I have an aftermarket water temp sensor in the upper radiator hose. Finally decided to drive it home from my buddys shop and about halfway home (from the shop home about 20-25mins). I kept my eye on the temp gauge and it would slowly creep up to 190F then slowly to 200F. It was also around rush hour time so there was a bit of traffic. Eventually it started to hit 210-215F so I pulled into a parking lot and let the car sit for about 20mins or so with the E fan on to cool it down. Once it got around 170F I got back on the road and right before i got home it was close to 215-217F and as soon as i got home i turned it off and let the fan run again for a good while to cool it down. I am in TX and it does get real hot here but im debating on either upgrading my E fan to something real high CFM, also might consider running water wetter and distilled water to help with the temps. Anyone know how hot is too hot? I definitely don't want to do any damage to the engine, it does have a metal HG but im not trying to run it higher than 190F. I did check the oil and coolant and didn't see anything to worry about.
