Hi, I bought an OBD2 blue tooth scan, now i can monitor my gauge everytime i drive, the problem is, after i have drove the whole day until early 7 at night the high temp indicator flashes when temp reaches 96 degrees centrigate then fan starts to turn on, then authomatically turn off at 93 deg centigrade, i have replace a new engine coolant sensor and thermostat but the problem still goes on. but when the AC turns on the temperature become lower untill 88 deg. this car is a taxi. can you tell me what the cause is?
