Changing thermostat - what is the proper way - removing the throttle plate or exhaust pipe?

usually the thermostat is in line with a coolant hose. It is usually mounted on the engine block.|||Depends on what kind of vehicle.|||knowing on what might help|||remove the muffler bearing first then the throttle plate then the exhaust pipe.|||When changing the old thermostat out and replacing it with a new one, one must first drain the radiator fluid and then remove(most typically although not always) the coolant intake pipe bolted to the engine block(which means removing the old gasket and applying an new one too). However, some cars have the thermostat INSIDE the coolant intake hose itself. Which leads to a whole new meaning to %26quot;pain in the butt%26quot; when it comes to replacement.|||I think you%26#039;re describing a GM 3.1 or 3.4 engine, and if so you dont need to remove either. Just a few hand acrobatics and you should be able to sneak around the pipe and remove the two bolts holding the housing to the block. After that just replace thermostat and gasket, add antifreeze. Pat yourself on the back and use the money you saved by buying the movie Cloverfield on blue-ray.
