    So I recently noticed that after sitting in stop and go traffic my thermostat says I'm running hot almost reaching the top white line but never to it and definitely not in the red. As soon as I start moving again the thermostat drops back down to normal temp. So my question is what's causing it to act like this and what are some possible ways to fix the problem.

    you should run your car and see if the fan is turning on or not. sounds like it isn't turning on while you're sitting still

    For sure it sounds like the coolant fan is not kicking on.
    For the time being, also try running your heat on high if you ever are caught sitting in traffic, that will help a little.

    i had the same problem. its could be a number of problems such as the thermostat, the fan switch, or the fan itself. try changing out the thermostat first. let the car run with the hood open and see if the fan on the passenger side turns on when it heats up. if it turns on but notice you are still having problems with overheating in traffic, change the fan switch located in the thermostat housing.

    I just got hhome from work and with my engine being at normal operating temperature my fan didn't kick on. So I'm assuming that mean either the switch or relay is bad?

    Am I understanding it right the fan should kick on even at normal temp? Or just when it's outside of normal temperature range.

    It kicks on when the temp switch tells it to. Generally when the gauge is about halfway.

    The problem you are faceing has happened to me before.. ended up being a fan switch. Here is how to check:

    1. Make sure the keys are off

    2. Pop the hood and locate the fan switch ( mine is a 7th gen so it is on the front of the motor , as your is on the back by the intake manifold.
    Top View :

    Side View:

    3. Remove the fan switch terminal ( Red) By pressing in on the relase tab ( Yellow) and pulling out.
    [​IMG]

    4. This is what you have... now take the jumper ( any piece of small wire would do such as speacker wire)
    [​IMG]

    And place the wire into the two terminals :

    to
    [​IMG]

    After this you can turn the ignition of the car to ON ( ii) and the fans should start up... If not you should check the fan switch fuse/ relay, if both check out you need to look at the fan it's self.


    Assuming the fans start up you will need a new fan switch... since you already know where it is located you need to replace it..

    1. make sure the car is cold and has been siting for atleast 2-3 hours.
    2. slowly release pressure out of the system via the radiator cap( otherwise you will pull the switch and coolant will go EVERYWHERE!)
    3. remove the fan switch terminal and use either a 24mm (or equvevilant) deep socket ratchet , or wrench. ( you might want to put something under the thermostat housing to avoid excessive coolant spillage)
    4. replace with a new fan switch
    5. put switch teminal back on.


    * NOTE* you will need to bleed the cooling system, so park the car on a inclined driveway ( front up ) ... If no driveway is available you can use ramps. Then open the radiator cap and fill the system up with coolant... loosly place the radiator cap back on and idle the car untill the motor has reached normal operating temp, turn the car off and put more coolant in if needed. Finally place the radiatior cap back on and take the car for a test run just to make sure it doesnt overheat again.

    No problem! And My fan would kick in but only after the Temp gauge was on bust, and she was severly overheated! ( which I ran a major risk of warping a head!) :D
