Electric fan in lieu of Flex Fan

You guys that are running electric fans directly through a switch with no relay might want to seriously consider running it through a relay because if the switch overheats from age/current, and it will, you are gonna be screwed.

I was running a pusher fan only for a while with no relay through a switch, and luckily my indicator light that accompanies the switch started flickering while I was pulling out of my neighborhood so I quickly turned around and decided to bite the bullet and wire up a relay because it fried my switch.
I also recommend the same with electric fuel pumps.

I am running a flex fan and a shroud from a slant six motor on my barracuda and it seems to be working just fine.

I will throw the pusher fan switch if I am in stop and go traffic or red lights for added security but the flex seems to be working well.

Eventually I want to go with the shroud and factory clutched fan such as the one Mullinax is using.
