How does performance feel after installation—cooling speed and noise?

This compressor is engineered for rapid cooling response and reduced operating sound. Users should notice a marked temperature drop soon after startup and quieter operation, with noise maintained at controlled levels when installed and system charged properly.

• Designed for fast cabin cooling after startup
• Engineered to minimize vibration and operating noise
• Optimal performance when the refrigerant is charged to 70–80%
• Proper system flushing recommended before installation

Any installation or maintenance notes I should know?

Before installing, clean the vehicle’s A/C lines and remove debris or metal shavings to prevent premature failure. The compressor is shipped with oil, so only refrigerant charging is needed; fill to about 70–80% of the system capacity rather than overfilling.

• Compare pictures and OE numbers before buying
• Flush cooling lines to remove contaminants prior to fitment
• Do not add oil before first use; unit arrives prefilled
• Charge refrigerant to recommended 70–80% for best results
