Cleaning Procedure

• Drain the cooling system and refill with fresh water. With the engine stopped, circulate and heat until the water temperature reaches about 60° C (140° F).
• Add 2% by volume (20 liters/metric ton) Heavy Duty Cleaner (Emulsifier) to the circulating water. Heavy Duty Cleaner (Emulsifier) may be introduced by means of the chemical feed system or added to the expansion tank.
• Circulate water through the system for a minimum of 4 hours.
• After 4 Hours cool to normal draining temperatures. Drain the system and refill with warm water to prevent thermal shock. Recirculate for 1-2 hours. No heating is required during this circulation period. Be sure to overflow the system through the expansion tank to the bilge.
• Drain the cooling water system and wherever possible, inspect the interior. If the system is not completely free of oil, repeat the above procedure.

If medium to heavy rust is present, it can be removed by using treatment or a solution of RXSOL SAFE ACID / DESCALEX POWDER and rock salt. If any sacrificial anodes are present in the system, they must be removed prior to cleaning. After cleaning, the anodes can be replaced.Cleaning Procedure
