There are a number of operations on the passenger side of the engine compartment (filter change, coolant draining) which are much easier with the windshield washer cage out of the way. But that bottom screw...what a pain. I substituted two pieces of self adhesive Velcro ..I guess it's been two years ago...and that really makes removal and refitting an easy task. There have been no problems with oil, or heat degrading the performance. Now, you may ask, which side goes where, hook or loop? I thought about this long and hard, but I'll let you come up with your own answer. Have to put a little element of challenge in to this otherwise no brainer.
