Default Help!! Replacing Water Pump 85

The problem is this was going to easy, Haynes says to loosen the bracket bolt under the lower edge of the compressor clutch (easy enough) wrong can't get to bolt does anyone know what size it is? does it require an open or box wrench?

Thanks

I believe it's a big Torx head bolt. There is a notch in the compressor clutch you must rotate over the lower bolt for proper access. At least that's how it is on my 86...

I believe it's a T45 torx bit to take it out and as geezel1 stated there is a notch on the a/c pulley that has to be lined up right so the bolt will come all the way out.
