SCA PRECHARGED Coolant/Antifreeze

Product Description

Mobil Heavy Duty Coolant/Antifreeze is a phosphate-free, ethylene glycol based, heavy-duty diesel engine coolant.
Mobil Heavy Duty Coolant/Antifreeze provides optimum protection against cavitation erosion, corrosion, scale, overheating, and freezing for all heavy-duty cooling system applications. Because it is precharged with a high quality Supplemental Coolant Additive (SCA), Mobil Heavy Duty Coolant/Antifreeze requires no SCAs at initial fill and helps ensures proper chemistry is maintained at every top-off.

Mobil Heavy Duty Coolant/Antifreeze is a fully formulated universal formula coolant/antifreeze, having the advantages of low total dissolved solids, low silicate and incorporates nitrite to provide exceptional wet sleeve liner cavitation protection.

Additional advantages of using Mobil Heavy Duty Coolant/Antifreeze include its phosphate-free formula that reduces the risk of scale and state-of-the-art corrosion inhibitors that eliminate the need for expensive deionized water.

Mobil Heavy Duty Coolant/Antifreeze is recommended for use in On-road and off-road heavy-duty diesel and gasoline engines, as well as mixed fleets where both light-duty and heavy-duty vehicles are present.
