My ss sc has been overheating in the desert! I can not figure out what is wrong. I don’t have air In the cooling systems, I’ve already bled them 3 times to make sure. I have a zzp front mount heat exchanger and zzp high flow air to water pump, along with a new radiator, temp sensor, and thermostat. Also this morning when I checked my coolant tank I had pressure still in the system after 10 hours of the car resting. It’s overheating at idle and when I get over 3k rpm.
