COOLING SYSTEM PROBLEM FIXED

Those are cheapo, low-flow fans, and you're expecting the air to make a 90 degree turn right at the back because the shroud has no depth. No idea what the fan setpoint is, but it will spike a few degrees above that point even if it has enough capacity to cool it forever. It won't run right on the setpoint unless it's been on for a few minutes.

OE fans from modern cars are the only way to go in electric fans. 11 years with a Contour Fan and a 26" 3 row champion. I don't even turn the low speed on until 195 and it doesn't get above 200. I think anyone panicking if their car never gets over 210 is also overreacting as well.

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.
