Just ordered headers

**derekbuckner1** · 06-30-2011, 05:46 PM

My headers will be in a few days from now. I just wanted to make sure before I did it. When I remove the egr and air systems off my car during the install, will it cause anything more than an annoying code? It'll be a few weeks before I get it to a dyno and it gets tuned out

Nope. Just be sure to seal of the vacuum source line for the AIR and cap the EGR.

The vacuum source line... Is that the smaller of the tubes running down the driver side of the engine bay? If so it'd be safe to cut that hose off back where it can't be seen then plug it right

The vacuum source line comes up from behind the engine on the passenger side to the electric solenoid for the secondary air system. Not sure what line you are referring to on the driver side. Over the fender well you have your hood release cable and the secondary air hose that goes from the air pump to the diverter valve.

Thanks man. I never noticed the second cable until yesterday and just assumed it was a vacuum line. Probably the hood release. So no fuse to pull or anything?

Fuse and relay can both be pulled.

i think i have a vacuum leak, i hear an intermitant whistle on mine, from under the hood its hard to tell where its coming from, from inside the car it sounds like its behind the drivers side air vent.

But my AIR solenoid was on the back side of the block on the drivers side, one hose went from the AIR pump to it, then split from it to each manifold, I cant find the damn whistle.

I think he is refering that a vacuum line that goes to the front area of the car. In my car if i follow the small vacuum hose from the back of the intake to the small 3 way valve, one of the vacuum tubes goes inside the firewall(a/c stuff) but there another one that goes to the front of the car. this tube follows the passenger side of the fender to the front of the battery. i think it goes to the AIR pump but I can't remember. I disconnect it and cap the 3 way portion of it. I don't see what else will use this vaccum line going towards the front of the car.

Personally I ripped all that crap out (well I removed it and stored it just in case) when I installed the LT's on the 02.

See Post #5 -- he was referring to the hood release cable on the driver side.

OP: When you removed the diverter valve on top of the engine, what did you do with the electric solenoid that is mounted in front of it and the vacuum lines?

**derekbuckner1** · 07-03-2011, 06:15 AM

I am yet to remove them as the headers are still in the mail. Any advice would be great

yup i guess i miss it. Do you know the line im talking about jeff? I still can figure out what it goes to? When I was working with the PS cooler I opened teh AIR pump compartment and didnt noticed any vacuum lines going to it. So where does this vacuum line goes to? It goes towards the front of the car on the passenger side to the battery area.

**pajeff02** · 07-03-2011, 05:36 PM

There is a vacuum canister aove the splash guard in front of the passenger side front wheel:

I agree it gives it a cleaner look too.

Just pulled all the AIR last night. I had just got my block offs in the mail. Only setback was trying to figure where to run the hood release and where to move my grounds to to clean things up. I'm very pleased. With the harnesses that go into the solenoid and the pump, do you all just leave them and secure them? Or remove them? When I pull the egr the plug into that looks like it's gonna be in plain sight
