Dual fan relay

Summit RacingSummit Racing Verified Purchase

Easy install, can run 2 fans but only one output is fused, need to wire a second fuse holder if you run 2 fans. Found fans will keep cycling many times after the truck is off. Can not wire the relay to constant power or the fans will continue to run long after the temp has dropped past 160. A/C input can also use it to start fans before the relay does it automatically. Only used for a few days so can't comment on long term quality. ...read more

Very simple and pretty effective

Works well, only complaint is that the dial is very sensitive and takes some patience to set the right fan turn on temp .
