my fan doesn't come on when temp reaches 226 is that normal for 08 chevy cobalt sport?
Nope is should come on at a lower temp I think it should be about 180 degrees.
If fan is not coming on when it should check for power going to fan , check fan fuse and relay , check connection going to fan and also check coolent temperature sensor
A Cobalt of that year the fan usually turns on at around 220 degrees, check the coolant level cold, if at specs and your still concerned you can have the vehicle 'live data" scanned, that will show you the exact temp the cooling fans kicks in and what the EM is reading for engine temp, there could be an error between the temp sender and the ECT sensor, or it possible that the gauge is out of calibration.
