Manifold Gauge Set Connection: Notes

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. The 'manifold gauge set' is a most important tool for tracing faults and system efficiency assessment. The relationship between HIGH and LOW pressures and their correlation to AMBIENT and EVAPORATOR temperatures must be compared to determine system status (see Pressure / Temperature graphs). Refer to GRAPH - HIGH SIDE PRESSURE AGAINST AMBIENT TEMPERATURE  and/or GRAPH - LOW SIDE PRESSURE AGAINST EVAPORATOR TEMPERATURE .

    Because of the heavy reliance upon this piece of equipment for service diagnosis, ensure that the gauges are calibrated regularly and the equipment is treated with care.
