Foreword When performed on a regular basis, lubricating the parts of your vehicle is the least costly way of obtaining safe and reliable vehicle operation. Added benefits and savings occur when you check that the engine, undercarriage, and noise emission control parts are in good working order during lubrication.
Freightliner LLC distributes the following major service publications. Workshop Manual Workshop manuals contain service and repair information for all vehicle sys- tems and components, except for major components such as engines, transmis- sions, and rear axles.

20–01 Radiator Cap Checking WARNING Do not remove or loosen the radiator cap until the engine and cooling system have completely cooled. Use extreme care when removing the cap. A sudden release of pressure from removing the cap prior to the system cooling can result in a surge of scalding coolant that could cause seri- ous personal injury .
4. Drain the radiator , and flush the radiator until clean water flows from the radiator . Remove the flushing gun. 5. Close the petcock at the bottom of the radiator . 6. Connect the hoses. Y our hose clamps can be either T -bolt clamps (see Fig. 3 ) or Breeze Constant-T orque clamps (see Fig.
the coolant level is between the MIN and MAX lines on the surge tank. 7. Fill the radiator with coolant. Use a mixture of 50 percent water and 50 per- cent corrosion-inhibiting antifreeze to protect the engine to –34°F (–37°C) year round. See T able 1 for engine cooling system capaci- ties.
during this procedure, the fan could engage, which could result in serious personal injury . 2. Inspect the electrical connections and wires to the fan clutch solenoid. Secure the connection, if loose; replace wires and connectors if damaged. 3. Clean the fan clutch air solenoid valve filter , if equipped.
