ok I aquired a late 90's electric fan from a crown victoria. its a perfect fit with my OEM thinner radiater.( i tried a thicker aftermarket radiater but its too thick). I went and bought the Advance Auto electric fan relay setup its all wired properly. its a two fan design so i set both wires to my 10 gauge supply to the fan. and there is 10 gauge feeding the relay. i currently run a 30 amp fuse for the fan but it blows at random times. that and the relay doesnt work all the time. Does anybody know of a really reliable fan relay setup with a temp sensor and A/C override? and is 30 amp enough or should i use a 50amp fuse??
