Should you have an "F" engine VIN code, the only thing that your vacuum runs, is the turbo wastegate. It can be kind of a waste (no pun intended) for the serpentine belt to be spinning a pump, to create vacuum to hold a wastegate closed. Should you have a problem with the wastegate system and want to convert over to a manual spring system for handling turbo boost pressure, you can delete your vacuum pump.
For those who one vans and some older model trucks, you should verify that nothing else like vacuum actuators for HVAC comfort controls are using the vacuum pump too.
You should read up first to see if this modification is right for you before proceeding.
To delete your vacuum pump, you will first need a shorter belt. Generally it has been reported that 1" shorter belt is what is needed. Because belt routing is different for some production years, you should check out what you are starting with.
To remove the vacuum pump only takes a few minutes, as long as you got the proper parts the first time from the part store... then it could take longer if not....
1. Remove the top portion of the fan shroud. (10mm heads)
2. Using a 1/2 drive ratchet, remove the tension on the serpentine belt, then slip the belt off of any pulley.
3. Using the 10mm socket there are three mounting bolts that hold the pump to the bracket. You rotate the pump pulley to access these nuts. After you loosen the third one, is should come free.
4. Maneuver then pump through every imaginable position to get it out from between all of it's next door neighbors. There is a vacuum line that goes up behind the pump.
5. After you have said your prayer that "I hope I have the right size belt," you can see if you did or not. Follow the belt routing map on the fan shroud that you laid somewhere on your driveway. Make sure all the ribs are properly in place on each pulley and nothing is hanging half on and off.
5a. If you do not have the right size belt, you can use the other car to go get the right size one, or work your way backwards through what you just did so you can use the truck and get the right sized belt. You won't get far without a serpentine belt in place.
6. Now reassemble the fan shroud, and make sure all crossovers etc are properly secured in place so they are not hit with the fan on start up.
Upon startup, you may even notice that the engine sounds quieter.
Hope this helps!
