Working on the cooling system
When working on the cooling system note the following:
  WARNING
Hot steam/hot coolant can escape - risk of scalding.
t  The cooling system is under pressure when the engine is hot.
t  To allow pressure to dissipate, cover filler cap on coolant expansion tank with cloth and open carefully.
Risk of injury as the radiator fans may start up automatically.
Unplug electrical connectors before starting to work in the area of radiator cowl.
  Caution
Overheating can occur if the filler cap is not fitted properly.
Close filler cap on coolant expansion tank (make sure it engages).
