Personal injury can result from hot coolant, steam and alkali. At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns. Remove filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand. Cooling System Conditioner contains alkali. Avoid contact with skin and eyes. |
Note: Install caps and plugs on all openings in order to prevent dirt or debris from entering the system. Cleanliness is an important factor. Before the removal procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.
- Drain the coolant from both sides of the radiator into a suitable container for storage or disposal. The capacity of the cooling system is
379 L (100 US gal) . Refer to Operation and Maintenance Manual, SEBU7173, "Cooling System Coolant (ELC) - Change" for the correct procedure.Show/hide table
