i recently changed my radiator and my fan wnot go on, the temp was going past the half way point, so i wired it directly to the battery for a temporary use only, i made shure the harness is plugged but the fan still wont turn on...could it be a fuse?

 

Try jumping the connector that plugs into the T-stat housing with a paperclip. I think the car has to be on but the engine doesn't have to be running, but anyways if the fans don't kick on when you jump the plug then there's something wrong with the fans like a bad relay or fuse. If they do kick on then you problem most likey is the ECT switch.

 

Oh I just realized you changed the radiator... Did you bleed the system after you filled it up with coolant? Air in the cooling system will cause your car to heat up real quick.

uummmm yeeeeeeeah...dont know what the hell is a ect switch, and t-stat but yeah...i think i already bled the radiator...but fan still wont start, the stock fan didnt go on, and neither did this one, but nothing wrong with the fan, just the harness

 

Its on the thermostat housing.

 

 

Check the underhood fuses, they are right next to the battery. They are designated very clearly on which is which.
