I know you need to drain the radiator of coolant in the older models. Not sure if the same applies for the 1.5L Turbo.
The OEM "manual" data is available online today--if you are willing to pay for access to it.Also we won't see service manuals for a while to come, unless the OEM manual gets leaked somewhere.
And that's why I love Civics!Gonna be a long time before you need to do this unless converting to Evan's Waterless Coolant.............I think the OEM stuff is at least 100000 mile services.
