Ultralife HD Antifreeze (Yellow)
Ultralife HD is ethylene glycol based antifreeze, which uses Organic Acid Technology and is free from nitrites, amines, phosphates, borates and silicates. The product will protect all engines from frost damage right down to –40oC (at 50% of total coolant volume). It also provides outstanding protection against rust and corrosion for all parts of the cooling system and is therefore recommended for all year round use. Ultralife HD can be used for up to 5 years or 500,000km in commercial vehicles, depending which is reached first.
