Not exactly.

I did (however) get sick of some of the people on the other RX forum I was using, now I am back.

umm.... could i still use my stock fan setup even if i have no place for the fan switch?

The stock fan doesn't need a switch, it goes around with the engine.

so wut exactly does the fan switch do?

I MEAN THE FAN SWITCH THAT GOES AT THE BOTTOM OF THE STOCK RADIATOR.....

it's the sensor at the bottom of the radiator with the two wires connected to it . .... on the lower drivers side of the radiator

cold start.

So you are saying that little sensor on the bottom is the cold start sensor?? Maybe thats why my car is a bitch to start, It hasnt been connected in months. https://www.nopistons.com/forums/pub...1047683664.gif

i mean it has to do with the accelerated warm up thingy.

S5's don't have a cold start system, that was an S4 thing.
