Commercial vehicle coolants & antifreeze
Castrol's coolant and antifreeze range works to help your engine maintain outstanding performance and protection, even under extreme conditions.
Outstanding protection
Commercial vehicle engines run hotter than ever before. With heavier loads and longer journeys, engine cooling systems must work hard to combat high internal temperatures. It's vital to ensure you use the right coolant, allowing your engine to maintain optimum performance even in the toughest conditions.
Castrol antifreeze and engine coolants provide excellent engine protection against overheating, water freezing and corrosion helping to avoid unexpected downtime and maintenance.
Castrol RADICOOL
Castrol offers a wide range of antifreeze and coolants available in both concentrated and pre-diluted formulations, with selected additives to help prevent corrosion in the engine and cooling system.
The Castrol RADICOOL range features extended-life products that maintain performance even under extreme conditions, preventing both engine overheating and water freezing.
