(20)Cooling System-Add conditioner
|
At operating temperature, engine coolant is hot and under pressure. Steam can cause personal injury. Check the coolant level only when the engine is stopped and the radiator cap is cool enough to touch with your hand. Remove the fill cap slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury. |
|
| NOTICE |
|---|
Do not add conditioner monthly unless the engine has actually operated 250 Service Hours. Adding conditioner before 250 Service Hours will result in an excessive concentration of conditioner. Do not use AVSpare Cooling System Conditioner with Dowtherm 209 Full-Fill. Follow the recommendations with the Dowtherm 209 Full-Fill. All water is corrosive at engine operating temperature. Use AVSpare Cooling System Conditioner, or equivalent, to treat either plain water or an ethylene glycol solution. |
- 1. Remove the radiator cap slowly to relieve pressure.
- 2. Add .2 liter (1/2 pint) of AVSpare Cooling System Conditioner, to provide a 3% to 6% concentration in the coolant.
- 3. Replace the cap if the gasket is damaged. Install the radiator cap.
