W204 C350 coolant - where to purchase

[merc07]

I have the blue coolant, 325 - now G48 is it ?
I have looked everywhere, you would think it would be a straight forward purchase.

Apart from Merc, where else can this be purchased, I only need about 1/2 inch

Tech catalog states to use G48 for all models up to 04/2014. After that production date use G40. So the blue G48 is perfect.

The coolant was replaced 6 years ago when the oil cooler let go..
