Q: little weird-colored thing with a wire clip on it right bolted into the side of one of the two metal tubes that run in to the top of the engine sorry im pretty rusty on my mechanical-lingo. and i did mean the thermostat. no you didnt as the thermostat does not have wire clip on it....since its in the damn motor. holy fuck..are you meaning the temp gauge sender how about you just leave the truck at the mech since you seem too damn ignorant to own one. in the meantime can someone tell me where the thermometer is located the thermometer ya mean the thing that reads the temperature and displays it on the overhead how one would check it for leaks/problems hmmm... most thermometers dont leak so im assuming you mean the thermostat. follow the upper radiator hose the big 2 hose that comes off the top part of the radiator and heads towards the engine. at the end of it is the thermostat housing. underneath that is the thermostat. unless theres coolant puddled on top of the intake manifold this is not your problem. the typical problem with the thermostat is a failure to open leading to overheating of the engine. the easiest way to test this is to remove the thermostat and drop it in a pot of boiling water. if it opens up its good. if not... you throw it out. of course for the $5 or so that a new thermostat costs you usually replace it anyway - the boiling pot is just for curiositys sake. .
