>> IMHO, Nothing wrong with 200. People get paranoid about temps in a
>> Pantera due to its reputation for overheating. I believe that many
>> Pantera owners operate their engine's too cool. We boast of our engines
>> running at 185 on the highway; yet, that is less than ideal. 200 to 210
>> is a good temp range that allows oil to get closer to its ideal 225.
>> Some argue that a fan coming on at 180 allows the cooling system to get
>> on top of keeping temps lower - I really do not buy that.
>>
>> Anyway, your temp sensor acts as a ground for your fan circuit when the
>> radiator coolant hits 200 and allows the electrons to flow and fans to
>> run. Actually, SO Bill has a tech report at Pantera Place that charts
>> the accuracy, or better put inaccuracy, of Veglia temp gauges with
>> various senders. I suspect that you actually have a 195 thermal switch
>> and the inaccuracy of your gauge has you believing it is 200. If that be
>> so, your engine coolant is actually cooler that you are informed by the
>> temp gauge.
>>
>>
>> Id recommend that you run a 10 or 12 gauge wire, depending on the amps of
>> your fans, from the thermal switch to a switch on your dash. The dash
>> switch is subsequently grounded, in the closed position, using 12 or 10
>> gauge wire to the ground stud under the dash. It is better to utilize a
>> central ground on the vehicle. If you use an existing switch on the
>> center console, remove the daisy chained ground wire from that switch (if
>> it be attached), as it is to light to carry the amps of the two fans, and
>> use th
>> e heavier wire previously mentioned ground wire. 12G carries 41 amps and
>> 10G carries 55amps. 12G should be adequate for many 2 fan loads. SPAL
>> fans are higher amperage and you might consider 10G.
>>
>> This will allow your thermal switch to still contribute to the cooling
>> exercise, when you are distracted and not watching gauges while driving
>> in the city, and allow you to override the thermal switch and turn the
>> fans on at will.
>>
>> Good luck

>> The fans are not going on to 200+. I would rather them go on at 180.
