The thermostat in the '95 EX has failed open... yaaay.
While I was under the hood I could not help but notice all the thermo/temp senders.

37750-PH2-014 015 THERMO UNIT (DENSO) 36.15 24.94
37760-P00-003 016 SWITCH ASSY., THERMO 52.97 36.55
37773-PT3-A01 018 SWITCH, THERMO (A-106) 60.82 41.97
37870-PK2-015 019 SENSOR ASSY., WATER 38.20 26.36

I thought there was a break down/labeling of each sensor in the FAQ but didn't see it.

What I think the senors are
#15 Temp gauge
#19 ECU temp sensor
#16/17 Fan switch
#18 fan switch

TIA.

You got it, mike. Obviously make sure you don't install 16 and 18 swapped.

Do they act as ON and OFF switches for the fan relay controls?
Or is one for normal temperature threshold switch and the other is for emergency going Chernobyl, need both fans on, activation?

16 controls the fans with ignition on 18 controls fans with ignition off

obviously 16 has a lower threshold for heat approx 190 degrees vs 205 or so... est.

16 will run both fans 18 will run only radiator fan
