Do I have to open that drain even with using the backflush kit?

If you only want to clean the rads out, then no. If you want to clean
the whole works out, then yes.

Heater core bypass valve broke Was: Flushing the cooling system?

Alright. While attempting to get the top heater hose off the valve, the
hose fitting snapped like a twig. So I had to remove the valve and run
both heater hoses to the firewall. Will this be a problem? I also
plugged the vacuum line going to the valve, is that the proper thing to
do?
Please forgive me for being a PITA. :/

Nope. Not near as much as having that snap while you were on the road.

Yep. Otherwise you will have a vac leak and that can cause all sort of
wonky things.
> Please forgive me for being a PITA. :/
Ok. :)
...seriously.. It's failure to ask questions that is bad. :)
