Temp will climb until it gets to the fan-on temp, which is typically 220-225 range from the factory. So don't be alarmed about temps up to that range.
Just a note - the later Quad 4's (94-95) and 96+ LD9 all have the t-stat located down at the pump/inlet, and for this reason is a 180F t-stat stock.
And yes, 190-195F is where they tend to cycle assuming good driving airflow. When sitting still it will continue to climb beyond until fan starts.
