Cooling System - Check
Check the cooling level in the radiator.
1. When it is below the sight glass (1) shown above
2. When the coolant level drops due to evaporation, add
50% water-antifreeze mix only up to the full line.
3. Periodically inspect the coolant system for obstructions
and debris. Clean out the cooling system and the engine
compartment as described in the Cummins Engine
Manual.
