Follow their instructions, but to save time: - Don't remove just the coolant tank, remove the battery & tray also. http://pg.photos.yahoo.com/ph/atlsportrider/detail?.dir=/5617&.dnm=aba3.jpg&.src=ph - Their instructions aren't perfect clear. Assemble the bottom part 1st with rubber body. The bolt & washer will be inside and in a recessed hole. The extension will be underneath and fitted into the bottom.This will only work well in one of the holes. The other hole will have the view tube fitting in it. Make sure the tube is already attached. Holding the bottom in place, lower the whole assembly over the chassis bolt hole. If you are pushing bolt from above you can feel when you've found it. You will have a left over o-ringed bolt. - Orient the holes this way so it actually fits. http://pg.photos.yahoo.com/ph/atlsportrider/detail?.dir=/5617&.dnm=b7c6.jpg&.src=ph - When reinstalling the battery duct tape the back battery retainer in so you don't have to fish it around to get it back in the hole. Here's the finished install pic. http://pg.photos.yahoo.com/ph/atlsportrider/detail?.dir=/5617&.dnm=8f34.jpg&.src=ph
