tb42s coolant leaking from block

[scubasteve]

Gday guys I have a tb42s in my maverick. It hasnt been driven much lately cos I have been away for work but I managed to take it for a spin today. Didnt go far just few ks up the road then when I pulled up there was coolant dropping everywhere from what looks like some sort of plug in the engine block just above the sump. The old man reckons it could be a welsh plug or something. What do you guys reckon?

Your old man i right, its a welch plug. There are larger ones aswell as the smaller ones you can see in your pic. You'll need to take your exhaust manifold off to replace them but while they are out you should take advantage of the situation and thoroughly flush out the block to remove the rust/ scale that builds up around the bores over time

X 2 with the above great time to remove some scale and rust.
re fill with correct type coolant for longevity

Any idea on how to take the plugs out and reinsert? And how do I go about flushing the block?
