Drain Plug on The Radiator..Hard To Get At!

[postman56]

Hi everyone, I wanted to install a OEM block heater in my wife's 06 Pilot for it's a USA vehicle and didn't come with one, and at times in Canada we could really use it.
I purchased the block heater but for the life of me I couldn't get a good hold of the drain plug on the lower part of the radiator to drain it to get going.

There is a small window there but the radiator I assume hasn't been drained in years so it could be pretty tight.
Is there a tool for this application, for taking the dozen or so shroud clips off isn't really a option for me.

Also I think I se where the block heater goes in just to the right front of the block, but it's a guessing game as well.
Any help would be greatly appreciated for I didn't think Hi everyone, I wanted to install a OEM block heater in my wife's 06 Pilot for it's a USA vehicle and didn't come with one, and at times in Canada we could really use it.
