EGR Valve question....

1486 Views 12 Replies 3 Participants Last post by  Ranger
I was trying to take off my EGR valve this afternoon to give it a cleaning. I unplugged its connection and then on the firewall side of the valve there is a bolt that has to be removed and on the front bumper side of the valve there is a "nut" that has to be removed.

Now here lies my problem: Underneath that nut, on top of another bolt, there is a metal bracket that holds 2 chrome lines that travel underneath the manifold cover and loop around the injectors. This metal bracket looks like it must first be taken off to get to the underlying bolt that holds the EGR in place.

However, the chrome pipe that is welded to this bracket that fits over this bolt will not move enough to slip it over the bolt so that I can loosen the underlying bolt.

Can anyone of you who have Sevilles (92-97) please go check your cars and see if this is something that we all have or am I alone. The Helm's manual makes no mention of this bracket on the EGR bolt. Anyone who can help, please pitch in. Thanks guys.

The reason the Helm manual doesn't mention it is because what you are looking at is a product of the fuel rail recall. The bracket is brazed to the fuel rail as a hold down. I have not done mine since the recall but I believe you now have to remove the fuel rail (or atleast disconnect the fuel line) in order to get the EGR valve off. It was tough enough before but now they made it even harder. I am still not conviced that hold down needs to be there.
They should be under the silver beauty cover, not the manifold.
There are 4 of them. They are the studs that the 4 plastic acorn nuts attach to that hold down the silver beauty cover.
You need to remove the 4 studs that the beauty cover is attached to. They serve a dual purpose. Just remove the beauty cover and look at the fuel rail. It should be pretty evident where they are mounted and what needs to be removed.
You will have to unplug the electrical connection to each injector. After all the hold downs are removed, then you should be able to lift the rail with the injectors still attached to it. The injectors should be in rubber grommets of sorts so you do need to pull on them a little.
Never. I cleaned my EGR about a year before I had the rail changed and it was only slightly sooty. I'm looking for an '02 SLS so I doubt I'll ever need to do it on this car. I did remove the fuel rail last year on my wifes 3800. After removing the wiring harnes to the injectors and all the hold downs, I simply pulled the rail and injectors as a unit. I do not believe you have to remove the injectors from the rail. You will have to disconnect the fuel supply line from the rail, however.

As I said before, I am not totaly convinced that the brazed bracket on the EGR bolt is completely neccassary. One option (your call) would be to cut that bracket with a rotary tool or hack saw as close to the line as possible. You could then go to the hardware store and buy a hold down to slip over the fuel line if it was really needed to replace the one that was cut. Hell, you could even fabricate one for that matter out of some steel strapping or sorts if it was really needed so it would be removable in the future.
