reservoir.
Note: It is recommended that the cooling system be filled
at a maximum rate of 10 litres per minute. If the fill rate is
any higher than this there is a possibility of air becoming
trapped in the system.

working temperature and pressure.
Note: Make sure the cab heater control is in the hot
