I am in the process of cleaning up the engine bay and want to put my coolent tank under where the battery go's on an 87 GTA. There is room if I remove this black ball that is hollow. Does anyone know what this is and if I can remove it? I think it has something to do with emissions but I am not sure. If I remove it will it throw a code? Thanks,
Tyler

 

it is a vacuum resivor that i beleave assists the power brake system. i guess if i were you i'd plug the line and see how everything works.it dosent do anything for emissions

correct me if i am wrong but isnt that for the cruise control because i know it does not have to do anything with breaks

 

Vacuum reserve canister stores vacuum for when the power brakes or other vacuum assisted components need it.

If it is for the cruise control, then I am going to remove it, since my CC is gone now.

 

if is the the black plastic ball w/ a 5/32" vacuum hose connected to it then it is a vacuum reservoir for cruise control.

 

Are you guys sure its for cruise control? I don't have cruise, but I do have that ball. I've always wondered what it was.

 

if its located on the drivers side(Camaros) underneath the charcoal canister then yes it is for CC.

 

I figured that it was for CC, I mean my GAWD, how can a softball size chamber with a 1/4" line back up a basketball sized chamber with 3/8" line.

 

That black plastic ball is a vaccum canister. It is for all vaccum acutated accessories.

 

Yes, it's for vacuum-operated things like cruise control as well as HVAC controls, but not power brakes; if you'll look closely you'll see that the brake booster line goes straight to the intake.
