What makes a squealing noise when the clutch engages?
Hello, I have a 2006 Toyota Sienna with approx 64K miles. Recently, I am hearing a squealing noise when the AC clutch engages (AC is working fine and blows very cold air). When AC is off for when the clutch is not engaged – no noise at all…
Is the clutch still engaged when the AC is off?
No. When the AC is off the pulley and bearing are still spinning. When the AC is turned on, the clutch disc on the front of the pulley is pulled into the face of the pulley which is still spinning with the bearing. The clutch disc is attached to the shaft of the compressor which spins the compressor. insightful July 6, 2016, 4:47am #10

More than likely you did what is commonly referred to as smoking the clutch. What this means is you overheated it a little. This caused the smell you referred to. More than likely you’ve caused a little bit of damage to the clutch, but nothing the car won’t live with.
