Electric fan???

I have an electric fan and have use them for a long time. I recommend them in all of my customers hot rods as well...
I do not like the "whirling blade of death" as I call it..
First you have to run it as a puller which is much more efficient. Also a simple temperature sensor hooked up to a relay. Most parts store alternators are a little over 60 amps which is plenty. Those hundred amp alternators don't really do anything until they're up to a RPM... as in there not helping at idle in traffic any more than a parts store one... This is where a good battery comes in to kind of take up the slack for those moments when the alternator can't put out...
I'm a fan of electric fans...:D:D...
