use a 10 mm open end or socket to loosen the bleeder bolt, you can find it by following your upper radiator hose towards the block, the bleed bolt is clearly visible on the water outlet cover which is what your radiator hose connects to, fill up your radiator, run your engine, loosen up bleed bolt.. when you see a steady stream of coolant with no air bubbles than tighten.. I heard the newer models dont have a bleeder bolt.. :shrug:
