LS1FANS

ok i have my fans hooked up through a vsc. they come on when the temp reaches 210 and turn off when it gets to around 180. they also run anytime the a/c is on. i dont really like the temp riding about 210 would like it to stay closer to 180 but cant seem to get the fans to come on any earlier. also is there a way to have the fans runnin while the engine is off. say im sitting in line at the track and i need the motor to cool down. to hot. would be nice to turn them on while waiting to get my temps downany info will be appreciated

mine run all the time, keeps my temp at about 177* or so. i just used a relay.
black= grnd
white= acc/ign
red = constant 12v
blue= fans
this way i turn the truck on,with out starting, and they run. you could also put an rocker swith in between them.

where did you get the relay?
part number, how much........

[droppedgmc]

any auto parts store will have then. just a 4 wire relay. 10 bucks maybe

ok now i have a problem, what amperage are these fans pulling?
ive blown two fuses and cant find the problem. also what is the part number for that relay? any name brand or specific one?

[01Thunder]

is there a schematic for they way you wired them up? ive seen one on ls1tech but dont know if that is it

that schematic will work just fine, also, go to partsexpress.com and go to electronic parts, there is a 40amp relay there for 2$ or so, it's on the schematic too, the part number that is.

[01Thunder]

ok which slots do these go into ? i guess they are numbered on both sides of the fuse/relay box under the hood.
and then i can set the temps with edit correct?
on at 180 off at 170
or something like that.
