FLUSHING RADIATOR
If oil has penetrated into the coolant ciccuit, the radiator and expansion tank
have to be flushed and cleaned with the approved cleaning solution Solvethane**.
Procedures:
1. Remove radiator and expansion tank.
2. Pour in 2 to 3 liters (2 to 3 quarts) of Solvethane.
3. Shake radiator and tank thoroughly and drain when oil is dissolved (after 2 to 3 minutes).
4. Install cleaned radiator and expansion tank, and connect on coolant circuit.
5. Fill entire coolant circuit with hot water and flush thoroughly by replacing the hot
water several times, until Solvethane remainders are removed.
6. Check drained coolant for traces of oil and, if necessary, repeat step 5. Fill and
bleed coolant circuit as normally after finishing the cleaning procedures.
