i need help. my fan doesn't turn on but when i tested it by hooking the positive and negative up to the battery it works. should i just get a new fan or is there something else that i should check? also, does an aftermarket radiator requires a different radiator cap? not sure what brand mine is fluridyne or something like that. thanks

 

Check relays and fuses... or the wiring itself. And for the cap I don't think oem fit but maybe they manufactured them to fit oem standards.
