If the EGR cooler is bad, then you also want to install the oil cooler rebuild kit. The root cause of the EGR cooler failing is the oil cooler plugging up on the coolant side (coolant flow path is through the oil cooler and then on to the EGR cooler in series).

Lots of threads on EGR system deletes.

Personally I do not think you HAVE to delete the EGR system for reliability, but if you do, get a tuner that takes it into account (JMHO). Certainly if you properly delete the EGR system, then you have eliminated a source of some of the more common problems. If you keep the EGR system, I would consider installing the "BulletProof" EGR coolers.


.... and welcome to FTE!

 

The EGR valve is easy. 2 bolts, twist the valve enough to the left to have the "EARS" open up. Then stick some heavy gauge wire through the "ears" and use a pry bar through the wire and pull straight up. It will pop out. Or you can buy a tool to pull it out with.

Also need to get the gaskets for it. I don't have the part number handy. Someone might jump on here with it though.

Here is a picture of where the EGR valve is:

Here is the part number for the gasket and the two o-rings.3c3z-9p455-ab

 

I might add when you are done: flush the system with VC-9 and distilled water and then add a coolant filter system.

 

a new vlave comes with o-rings.
imo you dont really have to repalce the o-rings. clean it and lube the o-rings and reinstall. unless they are damaged. We do it all the time.

 

Is there just o-rings, or is there also a gasket?

Does the valve need to be positioned open or closed?

thanks!

 

2 orings one flat gasket. it is a normall closed valve if it hung open then is most likly broken and need a new one.

 

THANKS for that!!

 

Cheezit, how easy should the valve move? I can move the valve open and closed with my fingers, but it requires a little effort. Should it be hard to move?

 

ya thats about right. its not a big spring.

 

Two bolts and up and out. You'll have to work it back and forth and around to get it out, but that's all. New one drops in, bolt it up. Gasket is already on the new one, and likely will also stay with the old one as it comes off.

 

sorry not trying to hijack this thread but a quick question. I pulled my egr valve this past weekend at 77k miles (06 f350 normally the wife's daily driver, but we tow a 14.5-15k 5th wheel about twice a month in June - September). It was actually pretty clean, but I used carb cleaner and shined it up trying not to get anything in the holes at the base of the top. After putting it all back together it started right up and we went for a ride, about 1.5 miles stopped at a light and when the light turned the truck wouldn't go, I basically had it floored and it was putting out black and blueish smoke but it barely moved us to the side of the road, like it went into some kind of limp mode. Anyway, sat there for a minute trying to think what I might have done wrong decided to try to move to the other side of the road where there was more shoulder and about half way across the road all of a sudden it clears up and back to full power. no CEL or any other warnings or lights. Drove it almost 100 miles since then and everything seems OK. We are leaving this Friday for a week long trip with the 5th wheel going about 400 mile one way and I sure don't want to get stuck. Any ideas as to what might have happened? I'm not sure when/why the EGR valve cycles but could it be that the valve was just "resetting" itself after having been unplugged, removed, cleaned and replaced?
thanks

 

No.

They made EGR valve improvements in 2007. If yours is the original, I would buy a new one for the trip. I installed a new one in my 2006 last a few years ago. One of the improvements is a stiffer spring.

Problems immediately after the work quite often have a connection to the work. Not sure how, but it and the symptoms seem to point to the EGR valve.

 

Mike, what's your code? If it's P0401 EGR Flow Malfunction, chances are there's no replacement necessary. When I get that I pop it out, hit it with a tooth brush and bottle of carb cleaner, make sure everything is opperational again, and put it back in.
