The coolant bleed screw threads are stripped on the rear cylinder. Anyone have any experience with this and how to fix? The fitting/housing the bleed screw screws into is made of a composit material. The bleed screw itself has threads that looks like threads on a drywall screw (Verify Corse/wide threads) with a 8mm bolt head on it. Someone (previous owner, mechanic) overrightened the screw and stripp the threads in the composite fitting and the screw can’t be tightened enough to prevent leaking. I may have to buy a whole new fitting, but I’m trying to figure out how I can fix it without doing that. I appreciate the brainstorming.
