Coolant Leak
 

Hi guys, I am new to this forum so sorry if this has already been anwsered. I have a coolant leak coming from the rear of the engine and have located it to a round black plug. Does anyone have any idea what it is called or any part numbers. Look at pics below.

It is the metal cap in later years and on the second pic it is the round ball on the bottom left.

Its called a PLUG, HEATER WATER 90339-16001. Should cost less than $5 at a toyota dealer. They should have it in stock since its used on multiple models and years. I replaced mine a few years ago for the same reason. Here is a link that could help you find part numbers in the future. https://parts.lakelandtoyota.com/pro...oling%20system
