    First off, I want to thank everyone on this forum for being so helpful. I've just started my DIY journey with my Prius C and this community has been such a huge help.

    After reading up on this forum and watching numerous YouTube videos, I finally decided to try changing out my coolant fluid. Everything was going smooth until I tried reattaching this stop ring onto the drain cock plug. It popped off and went flying...for the life of me I can't locate it. Does anyone here know the actual name and or part number for this? I'm assuming it's not safe to refill the coolant and drive without the stop ring. Thanks in advance!

    Yeah it is not safe to drive it like that. I am trying to find if the ring has a part number but so far nothing.
