Hello world, the car is not overheating, 240 would be over heating
200 is not hot...today's fuel dictates a 195 degree min operating temp, 60% water 40% antifreeze, a bottle of coolant conditioner, a high flow 195 degree t stat and a blocked manifold heat control crossover. Running colder than 195 causes excessive wear and the oil never gets a chance to keep clean. However please follow the old school thinking as nothing we have learned in 50 years of going very fast counts.
PS
Car came from ma mopar with a 192 degree t stat
