Valvoline Cooling System Cleaner 250 ml

Effective cleaning agent concentrate for internal cleaning of radiators and heat exchange systems
Passes through the sediment layer and corrosion residues and, in the cleaning process, binds them to the fluid circulation and then removes them from the cooling system
Easy to use
Does not require special equipment
Suitable for all diesel, gas, and gasoline engines and other cooling and heat exchange systems
Ensures effective engine cooling capacity after coolant replacement

Recommended for use in the following cases:
- need to increase the cooling capacity of the radiator
- need to remove deposits from the cooling system
- clean the cooling system from engine oil contamination (e.g. after replacing the cylinder head gasket or engine repair)

Instructions for use:
Remove the old coolant from the system and refill the entire cooling system with clean tap water. Add Valvoline Cooling System Cleaner to the cooling system and leave the engine idling at operating temperature for 30 minutes. Then remove all fluid mixed with dirt from the system. (in case of a highly contaminated cooling system, repeat the procedure if necessary). Wash the cooling system with clean water. After washing, fill the cooling system with a technically suitable coolant and check the tightness of the system and the condition of the ventilation pipes. A bottle is suitable for processing up to 10 ltr of coolant. Note! In case of oil contamination of the cooling system, it is recommended to replace the rubber parts of the system with new ones. The reason is the harmful effect of oil on rubber parts.
