What does a vacuum pump do?
The vacuum pump aims to provide a vacuum to several different places in the engine bay. The booster on power brake systems is one of the critical components that require a vacuum.
The vacuum pump makes sure that the booster stays under constant vacuum to provide adequate braking force.
Emissions solenoids and turbocharger wastegate actuators also require a vacuum to perform as intended. If these parts don't receive a vacuum,
they won't function properly and trip a corresponding check engine light.

Everything about this experience was great! The part was very good quality, it came with extra bolts which really matters on a project like that, due to the location of the vacuum pump. Most importantly, the vacuum pump works great.

Pully was off ballance causing me to have to buy 2 belts because of it and then buy the part from Napa for $260 waste of time and will cost you more money in the long run. Gets 2 stars only because return was easy.

I was surprised to see that this part was indeed compatible with my truck and works perfectly fine I noticed my brake pedal feels better as before it would go all the way down and feel hard now all that is gone would recommend thanks.

The quality of the part was good, discovered the part was damaged when the mechanic installed it. The box was severely damaged and most of the screws were missing. When the mechanic cranked the truck, the wheel wobbled. Belt stayed on. Would have cost more if the mechanic had to remove it. I'm
