225 running a bit warm!!!

High-speed overheating = insufficient water flow. Low speed/stuck-in-traffic overheating = insufficient airflow. Both kinds of overheating at the same time = both problems together with probable buildup of rust and crud in the engine's coolant passages and/or a radiator, no matter how clean, that has too much solder junction corrosion to do its job effectively. Don't try masking the problem with a lower-temperature thermostat...find the problem and fix it.
