My water indicator either fell out or was knocked off. I checked my parts book and picked up the parts at a local suzuki dealer. When I went to install the parts the plastic sleeve that goes in first which is not threaded but has retaining notches will only fit if I knock it in with alot of force and thats a maybe. Do I have the wrong part our is their something else missing. The water pipe coming out of the engine has no threads or retaing groves.
