Mate if you dont want to purchase the filter housing removal tool all you do is have your drain pan under the filter location to catch the excess oil and grasp the filter housing and turn it anti-clockwise as it only threaded on, and unscrew it a couple of turns in which oil will start to dribble out,leave it for a few minutes until it stops and then very carefully keep the filter housing level while you fully unscrew it and lower it down and drain it in your oil tray, every thing else you need to know and do is in your new filter box including new O rings. Once you,ve done it you will wonder what all the fuss is about. By the way when you reinstall the filter housing with the new element in it,unlike a spin on filter you dont tighten it an extra 3/4 of a turn after it contacts the base,just nip it up.Once again the torque setting is on the box (instuctions ).Haggle with Toyota as the price can be as much as $10 different between dealers for the filter.By the way it holds 6.1 litres with filter change Oh okay, thats much better to know I don't need to by the little tool.
