View Full Version : What is this?

I was just wondering what this little thing is that looks like a small tank or reservoir. I just got the urge to clean out the inside of it if I can get it open, but maybe it doesn't even need cleaning? Any help on what it is would be helpful...

That's your EGR valve. :)

I saw a picture of a guy's car on here and his cord wasn't even connected to it

3.4s have egr valves still? I didn't know that... the 2.4s got rid of it a few years back... like 97 or something. If you have it, and you unplug it, good luck with the ses or svs lights. unless you get a pcm reprogram that eliminates it. the guy with it off probably didn't have the car on either, or he would probably be having nasty sounds of some sort coming from it. but then again, that was just what my mx6 did.

Is there a way to clean it by hand by removing the whole thing? There are only two screws holding it down and I prefer cleaning things by hand over just spraying some cleaner in there through the throttle body.

Why do you want to clean it so bad? Do you even have a reason, don't fix something that isn't broke, it makes no sense. It's not even a preventative maintence item(to my knowledge)

I was just wondering if it gets dirty over time and is going to cause problems later down the road if I don't clean it. Why wait until something breaks or gets really dirty and causes problems to clean it? I would rather just keep things clean and maintained so I don't run into any problems later on. I know nothing about the EGR vavle and if it ever gets dirty or not, I am just wondering if it does.

It stands for Exhaust Gas Recirculaltion.. so it's going to get dirty. :)

Things get dirty and they break sheem of life.
Realistically you are not going to take a chimny sweep to the exhaust pipe to clean it :) *poken a little fun*
Might do more damage then good
