Alright so this is what happened, my radiator fan motor has been getting bad and finally crapped out and blew a fuseable link, replaced it and the motor. Car keeps shooting up to 300*+ and it blew off my heater control valve, fixed that. Car was always shut off when it redlined to cool. So now that everytrhing has been replaced: thermostat, rad fan motor, wires, water pump(right before winter). It still shoots up to red line within minutes. And the fan doesn't kick on at all. What am I missing here?

It's usually the fan switch that fails. It's in the passenger side head between plugs 6 and 8. All it does when the proper temp is reached is ground the wire going to the fan relay which then sends power to the fan. You can test the wiring and the relay by grounding that green with white stripe wire that connects to the switch with the key on. If the fan goes on, the switch or connection is the problem. Lots of alternative solutions can be found by doing a search on this forum

ok so the sensor under the the 6-8 plugs is this(pic attatched) which sensor is this? and can i tap into this wire run it to a switch, ground the other side and it will turn on? sorry for the late reply

I can't see what's going on in the pic, but you can tap anywhere into that green with white stripe wire(closer to the relay would be easier) and run a switch like you described and as long as the relay and fan are good you should succeed

on that is some pics of what mine looked like but when i did mine i took out both factory relays and then put in aftermarket generics becuase my harness for relays wasnt getting good connection then found a keyed hot wire under hood and used it to provide power for the coil and then just grounded the other side of relay coil so when i insert key and turn to run posistion both fans run on my car i had a diff relay for each fan if you ahve any other questions or need more info let me know

I also got the fan to turn on by turning on the AC but the temp still shoots up. the fan was just replaced and it isnt colling the engine so what else could i be missing?

Found out I had no coolant running through the engine D: all the coolant in my resevoir drained into the radiator and got burned off. Can't believe i missed this. Filled it with two jugs of coolant and a bottle of water wetter and its running around 220* but the fans still arent kicking on?

what do you mean by no water thru motor id water pump not turning thermostat stuck did you bleed all air from system make sure you ahd right water pump these cars have 2 types a single serpitine belt turns counterclockwise and the others are clockwise also when car is running does those hoses suck flat or stay open is thermostat in correctly and correct temp 3 diff ones that are used depending on application
