Zac,
The Pulsar one seems about ideal with an 80 degree thermostat. When the
thermostat opens if there is no air flow through the radiator the coolant
temp will rise till 87 then the fan cuts in till the temp drops to 82
degrees. If no air flow then the fan cuts in again etc. If you have a higher
cut in temp then it takes longer to reach cut in but the amount of time the
fan is working will be longer before the cut out temp is reached. Chicken
and egg type stuff I guess.
The only rule is the cut in temp and cut out temp must be above the
thermostat setting I would think..
Cheers
Feral Errol

Andrew, no they are not unfortunately. I was looking for one that size but
there wasn't one in the aftermarket catalogue. I might ask an auto
electrician. I think the temp switch thread is M8, whereas the thermo
switches are M16.
I honestly have no idea what the optimum temperature switch is, I was just
going to go with the pulsar switch which from memory was on 87C off 82C. It
looked easy to wire too as it didn't have a factory plug. Terry might have
better ideas as to the temperature to use
btw I am going to fit the later bluebird 3 bolt thermostat housing as that
already has a large thread in the side (for some vacuum switch I think)
which should house a thermo switch easily :)
