i am not sure what this does it holds a vacuum but for what. i am putting on my new bumper and trying to decide where to put it. is it really necessary.

 

Yes it's necessary for proper operation of the HVAC system and cruise control if you have it.

I drilled a few holes and bolted it to the back of my bumper, you may even be able to reinstall somewhere inside the eng compartment.

 

i just got in from the garage i was taking the endcaps off and all that crap i came in here to search and find out what that thing was, so thanks ill just watch this thread

 

cars and trucks dont have HVAC

 

I'm sure people can figure out what i was talking about. It may not be a proper automotive term but it applies.

Cars do have a heating, ventilation and air conditioning system.

Maybe i mis-spelled something you can correct now...

 

I relocated mine to there. You will probably have to get some tubing though, mine was very brittle and broke when we moved it.

 

Ok im lost im an HVAC tech and to me i would consider whats in a car a small hvac system. u have your refrigeration unit and a heating system. plus u can vent in fresh air. what is the climate control systems in trucks and cars called?

 

that depends on your year, mine has the washer fluid bottle right there.

and i would consider whats on your vehicle an HVAC system.

and personally i dont think that ball is important, when i put my new bumpers on, i took it off, and just put a plug cap on the end of the hose running to it, my CC and heat still work just fine, my A/C doesnt work but it hasnt since i got the vehicle, we filled it up once and it all leaked back out so i said screw it, my A/C is called 55 with the windows down!

 

I'm pretty sure Howler_GT mounted his behind the metal crossmember thing that is behind the bumper using a small peice of stainless steel or aluminum and it made for a nice clean install that wasn't too far from the original location. There's some pics in this thread...

i just ended up mounting it to the little triangle piece that goes from the fender to the body to the unibody just used some short screws and it is up out of the way no problem now was never really sure what it was for thanks guys i will post a pic in a minute or so

 

here is where i mounted mine and the bumper and winch i have not got the rope on the winch yet

 

i just bought new bumper too and i need to relocate this thing...but your first picture doesnt seem to work...are we talking about that diagonal/triangular bracket towards the front bumper?

 

My OR-FAB bumper came with relocation brackets, and instrutions on how to mount it over by the master cylender. It worked out well there.
