Coolant change on the M40

[Gravy]

Hi guys

I've just changed the blue temp sensor (without removing anything off the engine - it was a total pain in the arse but I feel chuffed ). Now I need to flush tthe coolant and refill, Haynes say remove the cylinder block drain pulg but don't enlighten me as to where that might be!

Any help please as I'm dying to have this little puppy running right before I go to bed!

Cheers

I sorted it now, runs sweet as a nut, wish I'd done this earlier on when I first got her! Nevermind, should give better fuel economy and smoother running now!

Well done mate, not that hard to work on when you get used to it
