I went to buy an EGR valve at advance auto parts and they dont list/carry them for this model, so I went to autozone and they list two different valves, on way cheaper than the other, is there any way to tell which part number it is without taking it out(unless it it easy to get to). I failed NOX emissions by about 1 point and I was told by the mechanic thats what he thinks the problem is.
I have the 3.3L v6 90 grand caravan SE.

 

Can anyone atleast tell me where it is and if its hard to get off?

 

Look in a Chiltons or Haynes manual. They helped on my 99 3.3L EGR system.

 

I always had to get them at a dealer. They are on the battery side and one part comes out of the exhaust manifold with a vacuum servo attached by hoses. Easy to do... 2 bolts 1/2 hrjob good luck
