Interesting thought, Jim. I’ll go give it a shake, though I suspect it is tight. I refitted it a few years ago (putting the thermostat back in the process) and it was tight (and have only driven a few thousand miles since).
I’ve searched for that tool but ended up eyeballing it and crossing my fingers. No rubbing, so it must have been okay.
