Found some drips on my garage floor under the rear middle of my 2008 Toyota Corolla LE. The substance was dark brown and sticky. I was able to look under the car and it appears to be coming from the rear floor pan plug which shows as part #90950-01960. You can see some of the substance around the black plug in the photo attached.
I’m not a car guy, so my question is…what is the purpose of the rear floor pan plug and what substance could be leaking from here?
It doesn’t appear to be leaking that much anymore as I have not seen any visible drips for a couple days. Should I be worried? Is there a fix?
