HP KOOLGARD LL is a high-performance, long-life engine coolant formulated using ethylene glycol and advanced organic acid technology (OAT). It is phosphate, silicate, nitrite, and borate-free, ensuring superior protection against corrosion, scale, and oxidation. The coolant is designed to provide extended service life up to 5,00,000 km under standard conditions, significantly reducing maintenance frequency and downtime. Unlike conventional coolants that require frequent replacement, HP KOOLGARD LL uses organic corrosion inhibitors that do not readily deplete, ensuring consistent and long-term protection for modern engine cooling systems. When diluted with 50% clean water, it forms a robust heat transfer fluid that maintains cooling efficiency even under high thermal loads.
