In hot traffic my temps get up to 100C and sometimes 105, never any higher. The aux is on but it doesn't cool it down any, it still continues to heat up. It has a 79C t-stat so it is fully open by 82C or so. If I turn the car off at 100C, heat soak will make the temps rise close to 120. Is this normal or is something not right. Thanks
