    okay like the title saying, I have a overheating problem and I'm not sure which one is going out the water pump, radiator or fan? my car would overheat after 2 to 1 hour of driving around and to stop it from hitting the red mark i would turn the heat on full blast to drop the needle. I have change out the thermostat and flush the the coolant system and it still overheat. I need help on this, hope you guys can help me out?

    You should be able to hear if your fans are coming on. If they aren't have you checked your fuses? If both are in working order it's something else.

    possible air pockets? "burped" the car? Are you losing coolant?

    FYI you can verify the fans are working by connecting the green test connectors under the dash and turning the key to the second click. The fans should repeatedly cycle off-low-high.

    So plug in the test connector and look/listen to the fans. They should be off then low, then high over and over. If they don't do this I would check the spliced connections. Also do they cycle on and off if you let it idle for a long time?

    i know that there are two black wires and one of them is marge with a green wire, they do not turn on low then high it's on one stating i think and you can't hear it at all when it's on so i guess the fan is always on low, it's does turn on and off but you can't hear it at all

    just found out today that the fan was wire up worry and it was pushing air out the front bumper not pulling air in. i hope this should fit it
