It is important that the cooling system is always completely clean. Even a thin lime coating, tin floss or gel formation (too much nitrate additives), will prevent sufficient heat transfer and result in engine damage. When this occurs, you cannot remove the contaminants by flushing with clean water.
Fleetguard Restore and Restore Plus cleaners for cooling system work fast and efficiently. Restore cleans the system without damaging metal surfaces, gaskets, hoses or plastic parts in a powerful cooling system. We recommend that you clean the cooling system with Restore if you are going to switch to a Fleetguard coolant.
