Mazda 3 Block Heater Install
from this looks like is when dealer/Mazda installed the block heater needs to remove this first?
I guess they dropped it and left in my car? (I am from Canada, so it came with block heater)
Just like the thing at 8'45'' here.Looks like an oil drain plug to me but without any reference, no idea how large it is.
It does looks like the engine block coolant plug. The only problem to me is nobody here is aware of that there’s an engine block coolant plug exists on SkyActiv-G engines. This’s a great news for DIYers doing the coolant replacement!Just like the thing at 8'45'' here.

Hi @yrwei52. so from the video (I didn't go through all details) need take this out and let all engine coolant out, then plug in the block heater into the same place.It does looks like the engine block coolant plug.
