A/C Compressor Spacer Sleeve.
The Genuine Porsche A/C Compressor Spacer Sleeve 99612610271 is a precision mounting spacer used when securing the air-conditioning compressor to the engine on selected Porsche 996 and 997 high-performance models.

• Porsche 997 MK1 GT2 2007-09
• Porsche 997 MKII GT3 / GT3 RS 2010-11  

Installed between the relevant compressor mounting surfaces, the spacer establishes the correct distance required for the compressor mounting bolt and keeps the compressor correctly positioned within its support arrangement.

Although it is a small component, accurate compressor positioning is important.

The A/C compressor is mechanically driven by the engine's accessory belt and must sit securely and squarely in relation to its mounting points and drive pulley.

A missing, damaged, distorted or incorrect spacer can prevent the compressor from being clamped correctly. This may contribute to compressor movement, mounting stress, accessory-belt alignment problems, abnormal noise or damage to the compressor mounting hardware.

Replacing a missing or damaged spacer restores the correct factory mounting geometry and allows the compressor to be secured as Porsche intended.

What This Product Does:
The A/C Compressor Spacer Sleeve establishes the correct spacing within the compressor mounting assembly.

Its main functions are to:

• Maintain the specified distance between compressor mounting points.
• Support correct compressor positioning.
• Provide the correct spacing for the compressor mounting bolt.
• Help keep the compressor square to its mounting bracket.
• Support correct accessory-belt and pulley alignment.
• Prevent inappropriate compression or distortion of the mounting assembly.
• Help distribute mounting loads correctly.
• Replace a missing, damaged or incorrect original spacer.
• Restore the factory compressor installation.

Possible signs include:

• Spacer missing after previous compressor work.
• Sleeve visibly crushed or distorted.
• Corrosion or mechanical damage.
• Compressor not sitting squarely.
• Compressor movement at the mounting point.
• Mounting bolt difficult to tighten correctly.
• Abnormal gap between compressor and bracket.
• Accessory belt running out of alignment.
• Belt edge wear.
• Belt squeal.
• Chirping or rubbing noise.
• Compressor vibration.
• Cracked or stressed compressor mounting lug.
• Repeated loosening of compressor mounting hardware.

• Correct compressor mounting geometry.
• Secure compressor installation.
• Proper mounting-bolt clamping.
• Correct pulley alignment.
• Reliable accessory-belt tracking.
• Reduced mounting stress.
• Factory-standard installation.
