Engine Cooling problem
1986 Mazda 323 4 cyl Front Wheel Drive Manual 317, xx miles
Tried putting a cooking thermometer into the top of radiator with engine running. When meat thermometer read 200 degree F, the inside (instrument panel or dash) analog meter had barely moved off totally cold. Have in hand a Haynes manual for the 1990-2000 323 & Protege. Of course, this is the wrong year. I think that the sending unit may have been damaged due to overheating it.
Parts sellers' description don't list the resistance value of their new units.
Like to know what its ohms are when, let's say, 60, 160 & 200 degrees Farhenheit before I buy a new sending unit.
I think that this meter may be just for driver info & THIS sending unit does not interface with the engine computer or " ECU"?
That is, does the sending unit just directly feed that water temp inside gauge?
