AC mod and clutch plate spacing
Hey all,
I put in an 8 rib belt and pulleys on my 03 MM. This meant replacing the 6 rib AC pulley with an 8 rib pulley, which I did.
This was in fall of ‘23 when AC wasnt needed, so I never tried it until…
Yesterday I turned on the AC and got no cooling. The cars idle was rising and falling. I turned it off and got home.
I checked the clutch plate air gap with a feeler and got > .75 mm.
Apparently the 8 rib pulley changed the spacing. There are 2 washers between the clutch plate and the pulley, so I will take one out.
But before I start this work I was wondering if anyone else has had this issue or one like it and did they have any advice? I might be missing something.
thanks
