[Mgs] Coolant draining on an MGB

[PaulHunt73]

Even if you remove the radiator altogether the block is still half full of old coolant, and removing the water pump doesn't get much more out.  Remember the original poster was asking how to get the bad coolant out.  Having a drain point on the rad is convenient for a simple drain and refill, but that's all.

You can drain a roadster cleanly without that by shoving a piece of card under the hose and past the cross-member over a bowl, slacken the hose clip and push it right back, then push a blunt screwdriver up between hose and rad port.  It only trickles out, but I leave it to do that while I get on with the next phase of the job.

I'd be surprised if the later engines didn't have the drain plug (replaced the tap a long time before that) below and to the right of the oil gauge connection, but try as I might with stiff wire I didn't get any more than a rusty dampness below it.  Frequently clogged with casting sand, some have had to 'chisel' it out with rods after removing the head.

  On my '76B, with '77 engine, there is no drain valve. You have to pull the lowest radiator hose off the water pump to drain the coolant. It's a mess. Need a really wide pan on the ground underneath, and even then it tends to run along the front crossmember and steering rack and make a mess.
