221 degrees Celsius is 430 degrees Fahrenheit.

So what is the engine temp. when driving? Did you burp all the air out of the coolant system? Are you running 50/50 mix coolant? Has any type of leak fix been added to coolant? Has the coolant added always been dex-cool? Some coolants mixed with dex-cool turn into gel! Do you have headers? could be heat soak. Also if temps rise when engine running and car parked it is probably your water pump (impeller) issue. Stock thermostats start to open @ 195 degrees. @ 221 degrees f. car should start and run fine, it maybe a different issue. Have any of your ground wires been loosened if yes, check them.

Check for air in your coolant system. Coolant has to be replaced under pressure to assure that air won't get into the system. Air in the system is a common cause for overheating.

Stock setting doesn’t have fans cut on until much higher than you expect, low is something like the 221 you are seeing and high is about 227. I started troubleshooting mine the first time mine got into that range, but it’s how it’s designed.

I'm with you on this one. Get the battery tested before doing anything else. And sometimes when they check the battery and say it's good it still can be bad. If it's more than like three years old, you might just want to replace it. Also, one more thing to do is add the extra grounds in the trunk and the chassis.
