pretty simple and stupid question but hey, everyone at one time doesnt know where the piston is, but anyways, does anyone have a good picture that they can point out where the thermostat is and basic steps in removing it (ie. drain coolant, unbolt it...), also, if the fan isnt coming on until the engine temp gauge gets to 3/4 hot, does it sound more like the thermostat or sensor or switch or other??? btw, radiator and coolant are a few months old so those arent the problem


thanks
