Advice on replacing EGR Valve : 2000 Blazer
 

Hello all,
I'm having trouble figuring out what size socket wrench I need to disconnect my old EGR Valve in order to install the new one. I tried pretty much every size socket that was in my set, but nothing fit securely. The two bolts look to be standard size, I just don't know the actual dimensions. In the mean time I'm stuck on idle until I figure out what size will fit. Anyone know the exact size?

Another question: visually, I see the two screws that I'm to deal with, but I keep reading about this 'large' bolt that is underneath. I know nothing about a 'third' bolt. Is there something to expect after removing the first two?

Also, this is my first time dealing with the EGR Valve so any advice would be greatly appreciated.

Thanks a lot for you help and best regards...

It should be 10 mm, and just the two. Be sure to get a gasket with a screen in it to help prevent carbon build up. An extension with a wobble head will make the job much easier. Also, when you are putting the bolts back in, take a small piece of paper towel and line the socket with it so the bolt stays in nice and tight. Otherwise, it will probably drop out.

Definitely do this, or something similar. I lost one bolt on mine once putting the egr back on.

Why did you get a new one? Just take the old one off, clean it out, put it back on and return the $200 New one you got

Thanks for the advice, it's a big help! Thank you...

I just might do that. Thanks for the suggestion!
