What is a Vacuum Pump?

A vacuum pump removes air from a space to create an area with less pressure than the atmosphere around it. In the case of the vacuum pumps that we carry here at 1AAuto, they are primarily used in diesel applications. Diesel's have trouble creating their own engine vacuum because they adjust levels of fuel to make the engine rev up or down unlike the gas engines that are controlled by air flow. This means diesel engines don't have an intake manifold full of vacuum to feed off of like the gas engines do. Because of this, diesels use vacuum pumps to create the vacuum needed for some of the components on the engine.

How do I know if my Vacuum Pump is broken?

If you lose functionality of your vacuum operated components, then your vacuum pump is probably not pumping. It may be the pump itself or the power (or lack of) going to it. They often seize when they fail, so that would be the easiest way to know if your vacuum pump is damaged.

Can I replace a Vacuum Pump myself?

Yes, most DIY'ers should not have any trouble replacing a vacuum pump.  A service manual is always helpful for jobs like these because there may be "tricks of the trade" shortcuts that can be taken to speed up the job.
