Low silicate ethylene glycol based engine coolant – phosphate and amine free formulation providing extended service life protection for lead solder, aluminium, yellow metal and ferrous alloys.

For US, European and Japanese turbocharged and naturally aspirated diesel engines, particularly wet liner engines, operating in on-highway and off-road environments and arduous city stop- start driving conditions.

Not generally recommended for petrol engines. For Mercedes Benz, use Radicool NF.
