Slight transposition on my chart - should be MAN 324N which as correctly pointed out by Xalty -
MAN information would indicate D542 contains nitrite ( page attached and source of my info, Don ) As for Glysantin 9313 it seems as difficult as D542 to obtain info.
SCANIA on the other hand calls for nitrite free coolant G48 (correct) or D542 ?
I will continue my research, must be correct answers somewhere.
