5 Disconnect the radiator hose at D and allow the coolant
   to drain. Flush the system using clean water.
6 Clean and refit plug C. Make sure it is secure.
   Reconnect the radiator hose
7 Use the necessary mix of clean, soft water and
   antifreeze, see Coolant Mixtures. Fill to the COLD/MIN
   level on coolant reservoir B.
8 Start the engine and run at idle to circulate the coolant,
   top up with coolant as necessary.
9 Refit the filler cap. Make sure it is tight.
10 Run the engine for a while, to raise the coolant to
   working temperature and pressure. Stop the engine.
   Check for leaks.
   Note: Make sure the cab heater control is in the hot
   position. This will ensure the coolant mixture circulates
   through the entire cooling system.
