Hi wise ones,
I was hoping someone might give me the lowdown on the existence (and location) of a coolant drain plug on the engine block of a straight six 2.6L?
I looked in the manual and had a brief poke about but nothing obvious jumped out.
Thanks, Josh
 
I located the tap drain with the help of @marjon's link. Soaked in penetrating oil for a while. Tried to undo tap - snapped off immediately :rolleyes:

Got a spanner on the nut (can't quite figure out the need for the tap bit if there's a nut?). Removed it ok, but no coolant came out ❓

Does that mean it's drained (I still think there's stuff in there) or have I made a mistake somewhere?

When the tap works properly, fluid will come out the middle of the stem.

Poke a bit of stiff something in the hole see if it’s blocked if you suspect fluid still in there.

That's what I thought until I took the whole thing out and saw the back of it (picture 4). Nothing's coming out of the stem if the back of it looks like that, right?

It’s a taper seat, so the gap opens up, that center disc is the stem so separate from the outer nut.

Get a new 1 (you need it) and it will all become clear.

or grip the stem in a vice and try again it will show itself ;)

Eureka! Thanks for that. I delved into the orifice with a screwdriver, punched through a wall of gunk and a dribble of the devil's own diarrohoea started to ooze out. A longer prodder was subsequently employed... and whoosh!
