Ford Mustang A/C Compressor Clutch Q. Hello: I have a 1995 Ford Mustang, 3.8 liter V-6 and manual transmission that recently had an A/C clutch assembly that has stopped working per the mechanic, in his words, the magnetic portion that engages the A/C had actually fallen off. The compressor works and when it did kick on, the A/C blew cold.

Question I have is if I get the A/C clutch assembly myself, is it easy enough for a do-it-yourselfer to replace that A/C clutch?

A. I don't really know what you level of expertise is, but I will give you the procedure and you can decide if you're up to the task. You'll need a special tool, but I think you may be able to substitute something else to do the job.

REMOVAL:

1. Hold A/C clutch with Compressor Clutch Holding Tool T94P-19703-AH and remove the A/C clutch hub retaining bolt.

2. Pull A/C clutch and A/C clutch hub spacers from A/C compressor shaft.

3. If A/C clutch cannot be pulled from A/C compressor shaft, screw an 8 mm x 1.25 mm bolt into the shaft hole of the A/C clutch to force it from the shaft.

4. Remove A/C clutch pulley retaining snap ring.
5. Pull the A/C clutch pulley from the A/C compressor.

INSTALLATION:

1. Clean pulley bearing surface of A/C compressor head to remove any dirt or corrosion.
2. Install A/C clutch pulley on A/C compressor. The bearing is a slip-fit on the A/C compressor head and, if properly aligned, should slip on easily.
3. Install A/C clutch pulley retaining snap ring with bevel side of snap ring out.
4. Place one medium thickness A/C clutch hub spacer inside the A/C clutch hub spline opening and slide the A/C clutch on the end of the compressor shaft.
5. Thread a new 6 mm A/C clutch hub retaining bolt into end of A/C compressor shaft. Hold A/C clutch with Compressor Clutch Holding Tool T94P-19703-AH and tighten A/C clutch hub retaining bolt to 11-14 N.m (9-10 Lb-Ft) .
6. Check and adjust air gap.
7. When installing a new A/C clutch, cycle it 10 times at idle to burnish it and prevent slippage.

A/C Clutch Air Gap :

1. Measure air gap between A/C clutch and A/C clutch pulley mating surfaces at three equally spaced locations with Feeler Gauge D81L-4201-A or equivalent. Record the measurements.
2. If each of the three measurements taken is not within 0.35-0.85 mm (0.014-0.033 inch) , remove the A/C clutch.
3. Remove and measure the A/C clutch hub spacer. Select the appropriate thickness A/C clutch hub spacer to place the air gap within specified limits.
4. Install A/C clutch hub spacer and A/C clutch. Recheck air gap measurement.
