Perfect replacement for 2014 Cadillac ATS

### ⭐⭐⭐⭐⭐ Replacement Vacuum Pump from my 2014 Cadillac ATS 2.5L RWD
*by A***R on January 25, 2024*

I decided to buy a new Vacuum Pump for my 2014 Cadillac ATS because I was already in the process of replacing my Valve Cover Gasket due to it leaking. In order to replace the Valve Cover Gasket you have to remove the Vacuum Pump, and it was kind of a bi*ch to do so… Hence why I decided to replace it as well. I also went a head and replaced the Vacuum Pump Seal with it. I found some Videos on YouTube that were pretty helpful, so definitely check those out if you need to. I highly recommend that you remove the wiper arms, cowl, and that giant metal bar that sits underneath it. You can leave the wiper motor attached to the bar. Just loosen the two bolts, and the grommet should hold it in place. I’ve had the new Vacuum Pump in for a few days now. Hoping it lasts a long time… If I run into any issues with it I’ll come back and edit this review. But so far so good🤘
