High quality OE replacement part with all components needed to complete the job Product Features:Patented Four Seasons part that fixes the common OE problem of slugging Compressors and extends compressor life as well as solving the problem of a noisy, shaky compressor at start up which can damage the A/C systemTo eliminate system damage, the timer will cycle the compressor multiple times to push the pooled oil and refrigerant out of the compressor gradually before normal operation to help protect the compressor. When not used the compressor has to work much harder to push all of the oil out at one time causing stress on the system.
