I repeat what I said earlier, 200- 210 degrees in stop & go traffic is acceptable, as long as the temperature drops when cruising. If you want better results get rid of the flex-fan & do something about that restrictive shroud.
That’s only acceptable (at best) of you have at the coolest a 195 degree thermostat. If you get those numbers with a 180 thermostat the cooling system is highly deficient.
