As you guys probably know the EGR valve on at least the 95's are hard to get to. Does anybody know the wrench size nut on the small pipe that comes off of the valve?

 

That's a tough question. If I remember right it's a larger size -- but ??? All I can say is it's metric size. Try a couple wrenches for the closest fit where there's not much play and you'll be safe.

 

thanks. The largest I have is a 19 and it didn't fit but the space is so limited I had a hard time telling if I was even getting the wrench in the proper position. I guess I'll just have to buy a few larger wrenches and see what I can do.
