Not hard but I don't know what it takes on a 90. Previously someone mentioned the bolt 5/8 I think that is used as a puller for the RV2s. Suspect yours is newer and different. Frequently the places that sell new clutches will let you borrow the tools to change them. I'd GUESS it is like the RV2, ie you thread a bolt in the clutch . The end of the bolt pushes on the shaft and slowly pushes the clutch off. Kerryp --- Imp1983@xxxxxxx wrote: > Hi, > > How hard is it to change the coil on an A/C > compressor? It's on my 1990.
