COOLING SYSTEM PROBLEM FIXED

My daily driver has a switchable thermostat and runs 221 most of the time and 210 if the A/C is on. I also had a car that was made 30 years ago that ran at 203 all the time and up to 230 in traffic being normal and those cars lasted too. No reason you can't run 210 on an excursion when these cars had a 195 thermostat stock.
Just an FYI. Back when OEM electric fans first came out. There were several car models, that had a fan on temp setpoint of 230-240 degrees, and would turn off about 210
