Ok guys while i was stripping the front bumper i noticed this round cannister thing on the passenger side of the bumper.......Looked like it had a vacum hose type thing goin into it does anybody have a name for this part?!?!?!

 

the vacuum canister its pretty important

 

why?

 

the vacum helps control damn near everything on the jeep right now especially the heat

 

Ahh ok i remember i took it off my old XJ along with the front bumper because it was pretty messed up do you happen to know what it does?!?!?

I didnt notice any diff. after taking it off my old XJ.....

 

specifically im not sure but i kno that it ties in with the brake booster and the heat but as far as the cannister you are talkin about im not for sure

 

Thanks man now i atleast have somewhat of an idea of what it does lol......I guess before i trim my bumper ill have to remount it a little farther toward the middle of the bumper.....

 

With the vacuum canister disconnected your heat will still get hot and blow, but with it disconnected you can't switch what vents the air comes out of. So, if you had de-ice selected when you disconnected your vacuum canister, you would never be able to select you dash vents or floor vents. The only other thing I know of for sure that disconnecting the canister will do is in a pre 92 XJ. That has the vacuum front axle disco. It makes the vacuum disco quit working. You don't have to worry about that though.

 

Ahh ok like stated before ill just keep it and move it more towards the middle of the bumper......

Thanks guys.....

 

My xj doesn't have the vac pot in the bumper matter a fact I dont know where it is. 93 xj sport

 

I just moved mine up into the engine bay after I installed my after market front battle bumper. I put it right behind the passenger side front wheel well. It fits like it was meant to go there.

 

Its actually effects a host of things.....

The heater control valve doesn't open correctly to even let the heater core get hot.

The heat won't stay in any position you select.. it goes to defrost and stays there.

If you have the vacuum disco.. that doesn't work Only benefit there is that if the Jeep was in 4wd.. it stays in 4wd.

The emissions system doesn't operate properly...

Cruise control won't work...

 

Good idea man i should be working on her tomm. and ill look into that......

 

i got mine from a u pull it, cuz the one on it was busted.. i think i got it for like 5 bucks o somethin
