how do you remove and replace a vacuum pump?
July 30, 2009.

Okay listen up, the vacuum pump is located on the left side of the engine in the front, it is round, made out of aluminum, it is bolted on, with six Allen head bolts, after you remove the there are seven screws that you have to remove on the front where the diaphragm is located, I'm assuming you have a kit to overhaul it? Once you remove the screws and you see the diaphragm. Be very careful, because it has 2 one-way valves, that have to go back in the same order, or the vacuum will not work. Good luck.
