radiator fan switch temp ranges with thermostat temp ranges...

[Frederick Smith]

I match the switch with the t'stat. 87C to 87c here in the NE.
Two wire 87c switch is 823-959-481F (goes with 87c 035-121-113B 'stat).

My old IPC (remember Rods former company??) catalog shows a temperature
sensor, part # 034-919-369 90c/two pin grey,with a note that says
"used to correct radiator fan run-on. Mounted ona special bracket on valve
cover". Listed for the '81-'87 coupe. Anyone know about this? Was it
a TSB deal??
