Q: EGR Flow

asked by on

I have a P0400 error on my Ford Escape. I am attempting to remove the EGR valve. Due to its location, it is extremely difficult to access the nut on the EGR exhaust tube. I am pretty sure it is a 1 1/16 inch nut, but I have not figured out a way to adequately obtain enough leverage to get the nut off, give the limited space. Can anyone recommend a method of removing this nut on this particular make and model?

My car has 110000 miles.
My car has an automatic transmission.

In order to get the nut loose you will have to use a crow foot with an extension and breaker bar to get it loose. The space is limited and this is the only way to break it loose.
