Uh, I beleive the fan is controlled by the sensor in the bottom of the rad.
Not any sensor physically connected to the engine. The fan comes on only
when the rad is not radiating enough heat without assistance from some fast
moving air, or when the A/C is on. But that's just my observations from many
a make and models. Never wreched on the cooling system of the 90s. Perhaps
the 90's engine temp sensor is smart enough to know what temp the radiator
is currently at, and completely ignores the rad. sensor/switch.....
