I filled my resevoir today and before it was full to the top it dripped out the bottom. Is there an overflow designed to do that so it doesn't come out the top?

 

its a known problem...this is normal. just a poor design.

Yes, this happened to me the first time. There is a sticker (or should be) on the pillar of the front suspension that warns about overfilling and overflow.

Unlike many cars, the washer reservoir does not fill up and stay full at the filler neck. It overflows out of an overflow vent. So do not overfill or you will have a waste of fluid on the ground.
