Does anyone know where I can buy a new coolant 13mm drain plug? The plastic one on my car is sheared (by previous owner), so will need a new one. Thanks.

Do you mean Radiator lower plug..?
If its in place.. and Watertight..
Just do like everybody else and twist off the lower hose
Ive not reved on of those in 12+ years
Its either a metric screw..
or ask Shop4parts or similar

Hi. Yes, the radiator lower plug.
I see, I'll try taking the hose off and it it that way!
Many thanks.

The factory hose clip is 'single use'
Cut ..mangle.. that clip off
and replace with a worm drive type

This drain is not available as a separate spare part, but...
There is similar plug for older Mercedes/BMW, for example Google: https://www.google.com/search?q=febi+37595 (Mercedes coolant drain cock, red).
You must add some plumbing gasket/washer (rubber, plastic etc.) in case of o-ring not aligning, so the head of new plug will seal.
You cut the "FEBI" like that (picture below) and it fits the Grande. By the way, thread is unusually coarse pitch M12x2,5. That is (was) the main problem.
Bleeder (on the top of the radiator) is easier to replace, because standard thread (M10x1), there is plenty of products like that (plugs, drains, bolts).
To undo those, you should use hex tools, not 12-point (they "grind" the plastic). Don't over-torque while installing. Use some lube (silicone+teflon grease).
