Not sure what you mean by liquids. The cooling system is exceeding reliable. If you need to top that up (the measure is the wee opening seen on the inside of the legshield - about where your right knee is), take out the two phillips screws at the top of the legshields (that is the inside - the part that´s not painted). That releases the access panel that´s above the headlight - it´s positioned with tangs, so gently tease that down. Inside you´ll see the radiator and a whole bunch of stuff to do with the linked brakes (also a bunch of bugs, flies and other insects that get in there). What you want is the reservoir that´s at the back and has a black rubber stopper on it. Whip that off and fill with 50% water and 50% anti freeze, then make sure your coolant level is at \
