EGR Valve Location

My husband is going to be cleaning the EGR valve on our 2000 Olds Sillhouette, but we don't know where it is and can't seem to find a diagram of it. Is there a web site that has a diagram of it? Thanks

It is on the driver's side of the engine towards the back and on top. Here is a picture of what it looks like for reference:http://info.rockauto.com/Airtex/Detail.html?4F1051.jpg

Please keep posted if you able to access the EGR and have it clean. I am unable to access my 2k Olds EGR as bolts are facing towards the firewall.
I have a Check Engine Code 1404 but than I heard this could be a faulty code that requires an ECU flash.
