Car getting real hot....

When I'm driving on the highway non stop the car will reach 160 and stay there but if I start to get stuck in traffic it goes up real fast, if I shut your car off (160) it will go to 180 and higher but when I start moving it will come down a little bit 10 mins bumper traffic it can reach closer 190

This feels very cut and dry. The temps go to 160 ( too cold in my opinion) while driving. In traffic, it climbs. Sounds like you need a better fan.
