Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
A/C compressor
The compressor is driven via a ribbed belt on the engine when the A/C clutch engages (A/C ON).
Low pressure refrigerant gas from the evaporator is compressed by the compressor. After compression, the refrigerant gas (now high pressure) flows to the condenser.
The variable displacement A/C compressor varies piston stroke and output depending on load requirements and suction pressure.
