When driving around town at low speeds or the car is stopped at a red light it will start heating up, but once I get on the freeway it cools down back to normal.
I have same problem with you. I notice the electrical fans (two fans) is always in slow speed even the temperature in dash gauge already reach 80 degree Celcius. Then I use OBDII ELM327 to know the upper limits temperature to know when electrical fans working. Surprised me ! I run the car on the way and It works about 110 degree Celcius and at this moment the car already hesitate to run. I am not turn on the Air Conditioning at this test. Ussually, I turn on Air Conditioning to make two electrical fans working and in the morning & hot season from home to office (about 40km) the temperature can reach 80 degree. But in the afternoon it reach 105 degree back to home and car loose the power along the way back home. I add NO thermostat 50 degree which will ground Relay 14 to make right electrical fans working. Alhamdulilah now the max. temperature is only 80 degree in afternoon back to my home. Even I have P0481 fault in the car, I prefer to do this rather than loose car power and high temp in the engine. I want to re-setting ECM but don't know how to this. Any comment ?
CHECK THE THERMOSTAT. THERMOSTAT IS THE ONE THAT SENSE THE ENGINE TEMPERATURE AND TURNS ON COOLING FAN WHEN THE ENGINE IS HOT.

Cheak your fuse under the drivers side under the hood. Look in your manuel for fuel fuse. It looks like a little black box.

Remove the starter and jump the connections to a Battery to see if it spins. Make sure you connect positive to the positve end and the neg to the neg end. Hope this helps.

If your car is equipped with a 3.1 or a 3.4 litre V6 and you have preformed all of the above listed work then I would have to say its the intake manifold gaskets. They commonly blow on these motors. Just a design flaw, nothing but replacing them when they leak can fix this. Also run a coolant pressure test on the system to check for minor things like a leak that you cant see from visual inspection. Hope this helps.

The headlight is a Halogen that comes out the back.
Find the wire harness and follow it to the back of the light to a rubber cover. Pull the rubber cover off the back and find a holder. Unscrew or releade the wire "spring" then pull out the old bulb.
BR SURE NOT to touch the glass part of the new bulb.....
