Okay so I have a 1999 Navigator 4x4 DOHC. I have spent m ore than a few hours searching online trying to find out WHERE the EGR Valve is. Reason being service engine soon light came on and code reads P0402 (Excessive Flow)
ALL of the pics and diagrams I've seen show the EGR right there in front next to all of the other EGR system components. Just my luck my car is different. WHY? (Not a question just a sign of frustrasion.) Though I guess if you know that answer it would be nice to know also.
So I find one thread talking about taking the TB off and it's right there behind it. Not the case. Now I grab my flash light and mirror and go searching following the hoses as before and tada EGR about 3' from the back of the car stereo unit. GREAT!!!
I mean this thing is all the way in the back of the engine under the dash smack dab in the middle behind the intake. Reaching in I can't even touch it with my finger tips from either side or from the top. Only way I see of getting to it is to remove the whole intake.
So I have a few questions.
1) Is there an easier way to get to it?
a) Going through the dash in the cabin (probably stupid idea but maybe theres a hatch like on vans)
b) Going down from the wiper/cabin filter area. Is there a big enough hole to make it work?
c) Your idea?
2) Is there something that a few people can vouch for that will clean the system without taking it apart? LIKE MAGIC
Seriously though is there a good spray to use?
