Hi,
I am new to here.
I have a disoc I 97 mpi.
Can anyone tell me,
what temperature will activate cooling fan start and stop?
There are two fans in front of engine room.
Do they activate at same condition?
two monthes ago, i hear something like relay quickly switching.
After that, the cooling fan seem not work well,
and cooling water go overheat.
But if car speed go fast, for example 60kmh,
the relay sound will disappear.
technique man say rely and thermostat is ok.
what's problem? bettery? wire? ECU?
right now technique man shorten relay control line to let fan always on.

thanks
bryan
