Need a Resistance Spec!
 
Hi all,
Does anyone have the resistance specs for the temp switch over valve that sits on top of the thermostat housing where the upper rad hose comes in.
I can't find it in my CD manual...
Thanks.

Should be the 212F switch for aux fans....simply a switch that becomes a "closed" circuit at that temp.

If you are talking your 1991 124 , it would be a NTC thermister [ after 1990].
Specs are :
Temp C.---Ohms
20-2500
30-1700
40-1170
50-830
60-600
70-435
80-325
90-245

Expletive. :eek:
Now I'm one of those guys... :rolleyes:

Car is a '75 450SL. Sorry about that.

Do the readings listed stand up?

I believe in the 450 it has to do w/ fuel/timing, but correct me if I'm wrong...

My info was for your 124 chassis..............
