There's a bolt on top next to the cap. Remove that. Then take the top of the reservoir off. Under that you will see a nut at the bottom with a threaded hole in the center. remove that nut and the reservoir will come off. There are a couple of O-rings under that reservoir so be careful not to loose them. MAC's http://macsautoparts.com, sells a seal kit. Part #: 49-34844-1. It's about $16.
