Tough that the AC clutch failed, but good news that it is accessable for replacement.
I have not had such luch with AC clutches.
One in a Ford (Mercury) Capri failed internally, but it was impossible to replace without lifting the entire motor to clear the chassis rail !
Another on a Citroen failed (100 miles from home at night), distroying the drive belt.
I figured i would just drive home as i didnt need AC......but did not realise that the same drive belt also worked a hydraulic pump that Citroen use to power the hydraulic suspension, steering AND BRAKES !
I didnt notice initially because the system cleverly uses the weight of the car on the hydro suspension to maintain some pressure in the system. But the more you use the brakes and steering, slowly the pressure drops !
Once i figured out what was happening i "economised "on the use of brakes (manual hanbrake got a lot of use) ...steering, and actually tried to "pump"the suspension over speed bumps etc where possible.
I actually made it the 100 miles home , but with suspension on the bottom bump stops, no foot brakes, and incredibly heavy steering !
To cap it off, the headlights had to be switch off once i also realised the alternator was on the same aux drive belt and the electrics were running only from the battery !
So .. AC clutches are a component i am very aware of these days !
