Just bought this 2001 cherokee need some major front end repair once I got it running I notice this open vacuum line behind the passenger side front bumper what should be there

 

Vacuum ball..

 

It's called a Vacuum Reservoir. You'll need that for Cruise Control and your AC/Heat system. Junk yard will probably be your only source. See pics of the reservoir and the vacuum system.

Thanks, now I'll see if I can find one

 

Local jy just make sure there no cracks/holes .

 

Ken where are those diagrams from?

 

Google image search "vacuum diagram jeep cherokee xj"

 

From Factory Service Manuals. I added a few things to the engine bay vacuum diagram that you won't find in a FSM. And I added "Inner Fender Liner" to the bottom pic of the reservoir.

 

would a Grand Cherokee Vacuum reservoir work ?

 

Any will work finding a place to mount others is the the key.

 

thanks everyone, found one at teamcherokee.com

 

I pulled my off and plugged the line so it would seal. Everything still works on my 2001 so I'm not sure if you really have to have it.

 

Wait til you're going uphill some time needing the heater.

Or using cruise control under a load.

 

Maybe, but I have 30k on it after I took it off. Just not a clean place to mount with my new bumper.

 

Relocate it to the engine bay.
