Notes: DeSlugger -- Recommended to Eliminate Compressor Damage on Vehicles with Low Mount Compressor; OE No. 89023460 or 25891791; With 4 Groove, 10S17F

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 system
• To 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.
• For use on 09-00 GM series with Denso 10S Models
• Connectors included for easy installation
