as you face the engine the thermostat bell is on the right (drivers side) Follow the radiatoe hose. Remove the two bolts and raise the bell still attatched to the hose. the thermostat is there with the rubber seal. You can gently pry the thermostat out with a screwdriver or something similar. Put in new thermostat be sure it is the same as the old one, and then replace or change the seal (be sure it is the smae size and thickness as the old one as I got the wrong size from Napa) Then replace the bell, and tighten, but not over tighten. I hope this helps!

I will assume your alarm system is factory installed, which makes it a passive system. This being said there has to be a "valet" switch for the alarm system. it will be one of two places, first check the obvious and look at the dash panel under the steering wheel, there might be a pushbutton kill switch there, or a rocker switch of sorts. If no luck there, the blinking status light that is on your dashboard might be the switch itself. Try "GENTLY" pushing it in. if it does push, the red light will start to double blink, this is normal. If neither of these solve it, call yoru local dealer and ask them where the switch is. Good Luck
