i see. im planning on taking that on out and putting a more effeciant electric one. these will not cause any probs? and also should i buy a new thermostat? if so where can i just get the thermostat?

i would also throw the lower temp fan switch in there, so the aux fan turns on at a lower temp. how were you planning on wiring up the additional electric fan?

there is the understeer wiring diagram for wiring the second electric fan to turn on the when the primary aux fan turns on or you could run it into a switch in the car....

you can buy a t-stat by itself from the stealer or online here (the vendors). you can also buy the lower temp fan switch from them.

make sure not to power the second fan from the first fan, and use a relay.

oh i see, an adjustable t-stat for the second fan. I was talking about a new lower temp t-stat for the car for the fan delete.

so what temp would you set the new fan? how big is the new fan? Our fans are pretty powerful in our rides.....
