does anyone no how to hook up the elctric fan for a 54 chevrolet radiator Fan Link---> http://www.classicparts.com/1947-54-Electric-Fan-Shroud-16-Single/productinfo/78-881/
The best way is to use a temp sensor...there are many kits out there, Hayden usually has one at your local parts store. Just wire up like the directions. You can also wire with a toggle switch and a relay, but you better remember to turn it on before meltdown.
I used a thermal switch that screws into the block. The electric fan is just for in-town cruising,but also connected a toggle switch so I could turn it off when the engine isn't running. Russ is right,remember to turn it ON when you start it up. Sorry if my post sounds confusing. I know what I mean LOL
