I just changed mine yesterday and these tips listed above were unfortunately incorrect.

Step 1 - Open the passenger door
There is a panel that has no screws on the flatside of the dashboard which faces against the closed door at the jam side. Use a body tool and pry the panel carefully exposing the inside area of the glovebox. If possible dont do this in cold weather because the tabs are plastic. Inside the panel you will see one small tab that the glove box has a 1/4 plastic clip seated in the tab.

Step 2 - Open the glove box. Remove the 3 hex screws on the top interior row of the glove box.

Step 3 - At the right and left corners of the bottom of the glove box remove the two front facing screws on the lower hinge.

Step 4- At the very bottom parallel to the floor there are two more hex screws remove those (they hold the plastic vent in place underneath the glove box. Pull the vent downward to release the tabs.
IMPORTANT: Dont forget to go back to step 1 and pull the small tab from the slot in the dashboard cover area ( Inside the panel you will see one small tab that the glove box has a 1/4 plastic clip seated in the tab)

Step 5 - Pull down on the glove box to release the clips.

Step 6 - You will see a black box inside. There are three tabs (right, top, and left) pull them individually to remove the front facing cover. Inside you will see the air filter. Remove and have airflow arrow pointed downward.

Reverse steps to reinstall. Be sure to line up the clips before pressing them back in place. Do not force them!

Good luck. I hope this helps. I did mine on the first attempt with no issues in about 10 minutes (I'm not a mechanic).

The coolant temp sensor is on or next to the thermostat housing. Just follow the upper radiator hose.
If you are looking for engine temp sensor, then look on side of engine block

Your circuit lights may be bright or dim according to how your electrical system was set up. It may dim when lights are off and get bright when lights are on. ------------------------------------------------------------------------------------------Car Diagnostic Tools
