Ok, so I checked on my stored 88 vmax last night ans I noticed there was an antifreeze leak under it, after investigating it I found that it is comming from that plastic valve located behind the front tire, looks like a drain valve, is this a common problem , and is there a simple fix without draining the antifreeze? I'm scared to mess with that valve, I dont even know if its turned in the right direction, the writing isn't level it seems to be twisted up on the left -- any ideas?
