Three coolant replacement questions 2013 I4
Greetings everyone. I've got three coolant replacement questions concerning the 2013 I4 motor:
1) Is there an air bleed valve anywhere on the coolant system?
2) Honda says to drain coolant using the engine block drain as well as from the radiator petcock. I'm a bit sceptical that removing the block drain plug will release any additional coolant from the system. Can anyone with experience shed any light on the topic?
3) Assuming that removing the engine block drain plug is a worthwhile task, what is the washer size for the plug.
That's it, and thanks.

Simple answers - IMO
1. No
2. Not worth if for a simple "drain and fill" of the cooling system.
3. See #2 but if you must I think it is 28mm..... 90401-PR4-000

Thanks, poorman212, your response is exactly what I was looking for.
I had another look at the block drain plug, and it appears to be located about 6.5" below the lower of the two radiator hoses from the engine, so there might be a legitimate reason to pull it even for a drain and fill.
Since it's so easy to pull the plug I'll do it if for no other reason than to satisfy my curiosity; I'll report the results afterwards.
Thanks again, poorman212, I really appreciate your help
