On the 96 N/A has anyone ever replaced the vacuum pump? This pump is only on for the year 96 n/a.
(Of course it is, :-( what a pain)
Any way would anyone know if I have to pull the full compressor bracket? To get at the bolts.
My pully is a solid piece and bolts go from back towards front, I'm assuming this pump is threaded.
Lol wondering if I dare open this can of worm orrrrr is semi decent once I get into it? Almost looks like I have to pull power steering pump?

Re: Replace vacuum pump
So your vac pump is on the drivers side? Have not run into this one yet but you should be able to remove without but I am just guessing.
Will check into another 96 in the lot today.

Re: Replace vacuum pump
Sooooo basicly I found a Google pix, in this pic they replaced the ac compressor with a bypass pulley (top right) with just a pully and JUST below you can see the 3 bolt hole where the pulley for the vacuum pump would be, that weird bracket on right is same as I have. Seems to go over steering pump as well...... Shezzz

Re: Replace vacuum pump
Now if you can imagine a vacuum pump and a compressor ,equals zero room to find a way to get behind, for bolt heads as it faces back to front,lol

Re: Replace vacuum pump
Try and see if you can see bolts from behind, a socket, extension and a univerval with electric tape around the joint will stiffen uni, should do the trick
