The A/C system on the non-turbo models incor-
porates a belt locking control function which
prevents the belts from being broken due to
a slip that would occur when the compressor
is locked. This function is achieved by the belt
lock controller located below the blower motor.
The controller compares the compressor speed
obtained from the compressor revolution pick-up
sensor with the engine speed and stops the

A high pressure relief valve is provided to limit
the release of the refrigerant into air to a mini-
mum when the high-pressure side pressure be-
comes too high.

HIGH PRESSURE RELIEF VALVE
The valve, which is normally closed by the spring force, is
forced open to release the refrigerant into open air when the
high-pressure side pressure becomes so high that it overcomes
the spring force. When the pressure is lowered back to the
normal level, the valve is closed by the spring force not to
let out any more refrigerant.
