Coolant
 

Hi guys,
I had a op on my leg in October, but have been neglecting my Scooby as I don't drive it much.
I noticed that the coolant was very low the other day, in both the plastic filler bottle and small tank.
Now I've done a rad fill a few years ago on my spec d, and was told to fill from the turbo pipe.
Do I do the same on my classic v2? Or just fill from the plastic filler bottle?
