Remove the fan shroud and fan. Disconnect electrical connector. The hoses have a clip that pulls out part way. A little force is needed when removing the hoses.There are 3 10mm bolts and a 13mm bolt. Loosen the 11mm bolt that the engine hoist bracket is on. Clean off any of the remaining gasket and bolt up the new thermostat. Push the clips on the hoses back into place and push the hoses onto the thermostat until you hear a click from the clip. When filling with coolant be sure to remove the bleeder screw next to the radiator cap to get rid of any air bubbles. It is a plastic phillips screw so don't use too much force when tightening.

hi gc, if you are getting cold air and warm air out of different vents with the a/c on, I would recommend having the a/c freon checked. if the system is low, it can cause cold air out one side and warm air out the other. if it is low, the system should also be checked for the source of the leak.freon has oil in it that keeps the compressor internally lubricated and when freon leaks out, moisture can get in the system.

You have to take the trunk liners off of both sides. There will be 3 13mm nuts on each side for the shocks, and under the car is a 16 or 17mm bolt that has to be removed. I hope this helps.

The thermostat is inside a black plastic housing, It is inside the housing assembly where both radiator hoses meet up by the engine. You can't replace just the thermostat, the whole housing has to be replaced,

many reasons for this. A bad relay can do it, or a wheel speed sensor can to. Also the relay may be at fault. You can have the codes checked for free at any Auto Zone and they will tell you what part is bad
