That seems a little strange, a solid plate like that? I thought GM generally uses stamped tin for the EGR gaskets and exhaust manifold gasket. Is there coolant in that side passage? The work shop manual states to drain the cooling system when removing the EGR valve?? It also looks like there are fours screws holding the plate to the head, can the EGR be removed by itself without removing the plate??
It’s located driver side on the firewall side on the block. Mine stuck open about a year ago and wouldn’t start. I also replaced the MAF sensor a couple months ago it was full of soot as well. EGR has an electrical connection to it, unplug and has I think three bolts in it.Can anyone tell me location of the EGR valve?
I want to clean it myself by removing and getting Moly egr spray cleaner. I read the GM doesn't clean them they only replace them
Has anyone removed theirs to clean?
