7. Fill the radiator with coolant. Note: Use a low-silicate ethylene glycol-based coolant, mixed with clean water and supplemental coolant additives (SCAs) suitable for heavy-duty diesel engines. See “Fluid Capacities/Lubricants” on page 187, “Coolant Compound Mixtures” on page 193 and the engine operation manual for additional information. 8. Reinstall radiator cap and tighten securely. 9. Start and run the engine until it reaches operating temperature. 10. Check the coolant level according to “Checking Coolant Level” on page 145.
Hydraulic System Never use your hands to search for hydraulic fluid leaks; use a piece of paper or cardboard to find leaks. Escaping fluid under pressure can be invisible and can penetrate the skin, causing serious injury. If any fluid is injected into your skin, see a doctor at once. Injected fluid MUST be surgically removed, or gangrene may result.
