Getting to the high pressure oil switch on the 2100cc waterboxer engines has always been a challenging endeavor, but with the right tools and approach, it can be made into a relatively simple exercise. We have sourced the perfect tool for the job in this 3/8" drive, 24mm medium-depth socket. This socket is deep enough to allow the connector on the tip of the switch to recess fully in, but short enough in overall length to get into this very tight spot (see additional photos below). We chose 3/8" drive, as 1/2" drive ratchets tend to be too bulky. You can even use it on your steering wheel nut! Grab one today and throw it your tool box—you won't be sorry you did the next time your oil buzzer starts acting up.
Tech tip: The right tools make the job possible, but you still need the right technique to make it as easy as it should be. First, you will need to remove the water pump/alternator and AC belts, then unplug the switch (the wire is often zip-tied to the switch, so a pair of long-handled wire cutters can come in handy for this step). Get the socket on to your ratchet (one with a thinner back is preferable) and fish it down in place. You may have to pry/push the engine tin down a bit to get a straight shot, but it does fit. You generally don't need to apply much force to get these switches on or off (torque spec is 18 ft-lbs.), so if it isn't angled perfectly perpendicular, don't sweat it, you just need to break it free and then it can be spun out by hand.
