GUARDIAN GRC-38non-acid radiator cleaner that removes

Description : 

GRC-38 is a non-acid radiator cleaner that removes

rust and scale, and emulsifies oil and grease from engine radiators /

cooling systems.

Applications : 

GRC-38 is widely used in the radiators and cooling

system of engines commonly found in automotives, generators,

tractors, excavators etc.

Advantages :

• Non-acid formula. GRC-38 dissolves rust, corrosion and scale without harming steel, iron, aluminium or copper. It is not corrosive to the skin, and is safe and effective.
• Descales and cleans in one operation. GRC-38 emulsifies oily contaminants in the cooling system that cause foam and harm to seals. Foam is an insulator and reduces cooling efficiency. With GRC-38, the entire system is descaled, rinsed, and cleaned in one operation.
• Fast action. GRC-38 equires only 15 – 20 minutes to clean the cooling system once the engine reaches its operating temperature.
• Cost effective. For the average automobile, only 1 litre of GRC-38 is required for effective treatment, and with the yearly G-COOL change, keeps the system in top cooling efficiency. A very cost effective solution for maximum operating efficiency.

Instructions :

1. Ensure engine is off and cooled before draining the radiator of all its content.
2. Add 75% clean water and 25% GRC-38 to system to be treated. E.g. for a 4 litre radiator, add 3 litres of clean water with 1 litre of GRC-38 to fill the radiator.
3. Replace the radiator cap but do not tighten.
4. Run engine until hot and then run for another 15 minutes.
5. Stop engine and drain system. If solution is hot, allow to cool before draining.
6. Refill radiator with running water and leaving drain tap open, run the engine to provide continuous flushing.
7. When clear water is observed from the drain tap, stop and fully drain the system.
8. Check the system capacity and refill using about 50% water and 50% G-COOL protective coolant.
