Does anyone know what the normal operating temp of a '92 5.0 liter SEL
engine is? I replaced my faulty aux fan switch with a value of 85 Celsius
and both the engine and aircon runs cooler at 90 C. However, the aux fans
never shut off and are bound to break soon this way.
If I use a switch with a value a bit higher than the engine's normal
operating temp, then the aux fans won't have to be running all the time and
will only come on only when normal temp is slightly exceeded.
