I just replaced the 12V battery in my 2009 Prius. There was several inches of water in the compartment. I drained it and am planning to seal where the hatchback meets the roof since I read that is often the culprit. I realized I accidentally left the drain plug out under the battery. I'm not the most handy and it was challenging for me to get the battery out, can I just buy a plug that can be stuck in from the underneath side or do I have to take the battery back out? What kind of plug would be best? Thanks for any help.
you could clean the area and try something like gorilla tape. don't leave it open though, mice like easy entries
No do not do that leave all the rubber plugs out for Christ's sake they're supposed to be removed at PDI they shouldn't be they're.. eve water should pass not stand. every where those plugs should be carefully removed . Unless you driving thru floods regularly. Even then water needs to pass.
That can't be right. Every Prius (not to mention every other Toyota model) I have seen has all those plugs installed. I do not believe that every Toyota employee who is doing PDIs has misunderstood the factory process. Sure, leave it out temporarily if you have a leak to avoid standing water. However, once the leak is fixed and you no longer have water accumulating, then it is okay to reinstall the bung.
Water needs an interstate to travel thru you're vehicle . Not starting and Znd collect water shows up thru season changes etc leave em out in rear . Like you're boat wen emptying
Another unintelligible reply, but no thanks. I have no interstate flowing through my car and I am not my vehicle, nor am I boat, whether emptying or not. I am quite satisfied with it all plugs installed as delivered.
See if you can find a PDI instruction guide I guess . I don't have it . I popped em out in 86 at Goodman Toyoda Raleigh NC. Celica 's Supra 's Previs ban etc
I'm speculating as well, but think those plugs go in, and likely it's part of the stuff dealerships are supposed to do to earn their $1500~ for Pre-Delivery Inspection. My guess, and somewhat confirmed when I asked Service for a replacement plug (one of ours was just plain missing, and they don’t just fall out), is that the holes are for some sort of restraining pins, used during shipping. The top-guns at Open Road Port Moody gave us our '10 with one plug missing, 40 psi in the temp spare (hey, at least it's got a spare), and a dead-as-a-doornail 12 volt battery (it had apparently been languishing in a back corner for 15 months). They also made a concerted effort to hide the 12 volt battery condition. Basically, that was the most I ever paid for a carwash...
