Changing coolant tomorrow...
 

Any tips?

Fill via the small rad cap on left above the engine I presume and empty via bottom hose removal?

Bleeding method?

Just getting ready for winter, and dont think it has been changed in while judging by the browny red colour of the water.

If it's not been changed, flush it through with some clean wter, or buy something to flush it.

Draining: there is a little tap at the base of classic rads, or yes, remove bottom hose.

Refilling: Make sure car heater is set to "hot". On the metal rad cap on top of the engine, there are some hoses. Remove the REARmost one and fit a funnel into it. Pour the antifreeze mix (50%, ok?), into this avoiding any "glugging". Keep doing so until you see the level in the metal reservoir rise to the top, at which point, remove funnel and refit hose.

Now, without refitting the resevoir CAP, start engine and wait for it to warm. Watch for bubbles, top up/mop up as necessary.
Once it's warm, refit rad cap, go a for a drive round the block, check level once it cools and refill, if necessary via rad cap and overflow.

Job done....no bleeding necessary, or possible.

Just the kind of comprehensive help I needed and expected from here.

What he said. I also found it useful the squeeze the bottom hose to expel any air locks after filling.
