Small Coolant leak

[Roverlord off road spares]

I had a small bit of coolant loss so I did some investigation, and removed the under body tray just to inspect.
what I discovered is a small leak coming from the drain plug. Access to it is really difficult, but googling a pic of the actual part shows there are a couple of small o rings on the plugs shank. Also noticed that some one has used that pink OAT in the system, so I intend to replace the pug, which means emptying the coolant and flushing it and adding the correct coolant to it.

looking under mine today too, looks like I have red coolant, given the pink weep marks at one of the pipe joints, so off the LR to get some blue coolant

Mine has red coolant, put there by the folks who rebuilt the trans and fitted the ENORMOUS trans fluid cooler. Had the radiator out and cleaned while the job was being done.
Is the red coolant a problem? Why are you changing back to the BMW coolant?

Thanks guys
