Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / October 2006EGR valve
I have a 1998 Mercury Mystique. My check engine light is on and I want to take the egr valve out to check out what I think might be a blocked passageway. I don't know how to get the valve off the exhaust tube. I would appreciate any help with this. It looks like it might just be pushed into the valve but I don't want to take any chances of breaking something. Thanks. Why not have the OBDII code read before pulling the EGR valve and possibly breaking it. The code will tell you if that is the problem.. >I have a 1998 Mercury Mystique.

I did have the code read and it said it was egr problems. The egr valve checked out to be ok so the problem seems to be with a blocked passageway in the manifold. I got info about how to clean this out with an old speedo cable on a drill but I can't get the valve off of the tube. I think the tube and valve are one unit that has to come off as a whole part, maybe even as an exhaust part. I could easily be mistaken though...

I went to the auto parts store and saw a new egr valve and the tube does not come with it. It looks like it is just pushed into the valve. There is a nut about 1 inch down the tube from the valve but it doesn't look like it does anything. > I went to the auto parts store and saw a new egr valve and the tube does > not come with it.

I didn't get the whole discussion here, but I just changed my EGR valve (F250, 460 cu in"). That big nut seals the unit and routes exhaust to your manifold. I couldn't get the nut loose, so had to cut it off and get another tube from a wrecking yard. MM^^ Thanks MM. I guess that answers my question. |
