Manual - Chapter 4 - Cooling

2. Cooling system: draining

  1. Warning: to avoid the risk of personal injury such as scalding, the cooling system should be drained only when the engine and cooling system are cold. Note also that coolant wil/ attack painted surfaces; wash away any spilled coolant immediately with fresh water.
  2. Place the machine on the centre stand so that it rests on level ground. To reach the radiator cap, the fuel tank and the radiator covers or fairing lower sections must be removed. Refer to Chapter 5 Fuel & Oil.
  3. If the engine is cold, remove the radiator cap by rotating it in an anticlockwise direction. If the engine is hot,having just been run, place a thick rag over the cap and turn it slightly until all the pressure has been allowed to disperse. A rag must be used to prevent escaping steam from causing scalds to the hand. If the cap were to be removed suddenly, the drop in pressure could allow the water to boil violently and be expelled under pressure from the filler neck. Apart from burning the skin the water/antifreeze mixture will damage paintwork. Where time and circumstances permit it is strongly recommended that a hot engine be allowed to cool before the cap is removed.
  4. Place a receptacle below the front of the engine into which the coolant can be drained. The container must be of a capacity greater than the volume of coolant. Unscrew the drain plug underneath the water pump assembly. Allow the coolant to drain completely before refitting the drain plug. Note its specified torque setting. The coolant reservoir may be drained by removing it from the machine and tipping out the coolant.
  5. The manufacturer recommends that the coolant be renewed at regular intervals. (See Maintenance - Schedule for Service.) If the coolant being drained is to be re-used, ensure that it is drained into a clean non-metallic container.
