FLUSHING RADIATOR - Radiator Removed - If there is oil in the cooling circuit, the radiator and expansion tank must be flushed and cleaned with "solvethane"**. Procedures: 1. Remove expansion tank in addition to radiator. 2. Pour in 2 liters of Solvethane. 3. Shake radiator and expansion tank thoroughly and drain Solvethane after oil has been dissolved. 4. Install the cleaned radiator and expansion tank again, and connect them on the cooling circuit. 5. Fill the entire cooling system with hot water and flush thoroughly to safely remove remainders of Solvethane, repeating this step several times as necessary. 6. Inspect the drained water for traces of oil and, if necessary, repeat step 5. Fill and bleed the cooling system* after completion of the cleaning procedures - see 17 00. Note: Solvethane attacks rubber seals, rubber hose, etc... Consequently it must not get into or remain in the cooling circult. Always conform with safety precautions for working with Solvethane (printed on containers).
