Condition
Some owners may comment on insufficient air conditioning performance and/or noisy compressor clutch assembly.
Cause
Premature wear of the compressor shaft seals. This wear will result in PAG oil leakage on the clutch drive and pulley, thus causing insufficient
engagement of the compressor.

build up. Once the rotor face has been reconditioned, clean area thoroughly. If the clutch pulley rotor face is badly discolored and/or damaged,
replace compressor assembly.
4.
Remove compressor shaft seals as identified in Section 1D2 of the Service Manual.
5.
Install the new shaft seal kit, P/N 2724954, and clutch driver, P/N 6580590, using the installation procedures in Section 1D2 of the Service
Manual. This new seal kit will include oil wick pads and a shaft dust seal along with the typical compressor seals. Follow the detailed instructions
