I think Upallnight was simply stating that the type of fluid your system requires would be on the cap/reservoir label if it was original. But if there is any chance it has been replaced there is always the possibility the a PO may have purchased a reservoir and lid with the wrong label(s).


Upallnight, please respond so you hit your goal!
