1.) if the car is second hand, the temp switch could have previously failed and the electrician of the previous owner simply bypassed the temp switch and connected it directly sa ignition, hence palagi siyang naka-on. imo, there are at least two reasons why this is not recommended: a.) the engine may have a hard time reaching the optimal operating temperature kung even before magstart siya is may fan na agad, b.) the engine/aux fans were not designed to operate continuously, baka umiksi ang lifespan ng motor niyan. replaced one on a previous car ('89 galant) and it cost around 3K.
2.) check your radiator, baka kulang sa water/coolant or may leak. same thing happened with our accord vti-s, and kahit patay na yung engine the fan was still running. kulang pala sa tubig ang radiator (maybe it's the car's way of crying out "uhaw na ko!" hehehe).
update ka lang po ng developments para maka-input pa ibang tsikoteers.
