Stabilizing the System

WARNING: This page is about a different car, the 2002 Jaguar XKR and 2002 Jaguar XK8. However, it is still accessible from the selected car via links, so may be relevant.
  1. Accurate test gauge data will only be attained if the system temperatures and pressures are stabilized.
    • Ensure that equipment and hoses cannot come into contact with engine moving parts or sources of heat.
    • It is recommended that a free standing air mover is placed in front of the vehicle to provide air flow through the condenser / cooling system.
    • Start the engine, allow it to attain normal working temperature and set at fast idle (typically 1200 to 1500 rpm).
    • Select full air conditioning performance.
    • With all temperatures and pressures stable, or displaying symptoms of faults; begin relevant test procedures.
