'91 100q After Run Fan

[DK]

My 86 4000 has an after run fan, and yes it is operational. If the
fans turns on when you connect the two wires, sounds like the
electrical side is operational. My sensor is located on the rear of
the head (well, bolted down with the valve cover nuts). It goes on
when after I come of the high way, or after having driven in stop and
go traffic, or after some hill climbs. Do note, it will take a few
minutes for the fan to kick in, and if its really hot, it will cycle 2
or 3 times.
Sensor is from a other junkyard car, I believe its 85c aswell. Not
sure if there is a sensor with different specs or any mods.
