Slide the fan into the lower 2 slots on the radiator (some have bolts), put the top 2 10mm bolts in, plug the wire connectors together.

 

i know that but how do you connect the wires so it will turn on automatically is there a sensor or somthing i connect it to

in a obd0 block there is a sensor on the back of your block that has two wires running to it, its next to your oil pressure sender which has one wire. run a jumper between the two wires for the coolent sensor and your fan will run whenever your ignition is on.

Which is not a good thing. You don't want the fan running unless your car is up to temp.

If your fan won't turn on by itself, and you hook a jumper between these two wires and the fan turns on, that means the thermoswitch in the back of the block is bad. Replace that so the fan will come on when it is supposed to.

On OBD-1 motors, the sensor is a single 2-wire plug on the thermostat housing. Same thing goes for testing that out. Wire it up like its supposed to be. Having the fan on all the time gets old real quick.

Yet still better than haveing a radiator and fan and never having the fan turn on so you overheat! I wasnt saying this was the best idea for the life of your car but it will keep your car from overheating while sitting still.
