Hello, the coolant Temp Sensor that is on the drivers rear of the block... Just a 1 wire job... If I disconnect that, will it affect anything?? Is that just for the gauge inside??? Here is why I ask... I want to put a new electric cooling fan in... One off of Ebay... I want the fan to come on a bit sooner than it does now.. They sell these kits with a switch and everything... I would have to put that new switch in... I was wondering if I could just take that out and put the new switch in there.... But then I want my gauge to still work... I am sorry if this sounds like a really stupid questions.. haha... Thanks for the help...
