ANTIFREEZE AND COOLANT

Coolants
Truck and bus engines run hotter than before causing more stress on their engine cooling systems. From vehicle to vehicle the materials that make up the cooling systems are different. If the antifreeze/coolant within the system breaks down this can cause a leak or damage to the engine.

Castrol’s antifreeze/coolant range includes the approved and latest technology products offering outstanding protection and longer engine life, maintaining performance, even under extreme conditions.
