    Hey all so I was just looking on eBay & found what looks to be a very reasonable priced egr cooler for $75 (+s&h). Would you guys think this is a good price? Apparently all the EGR valves with the cooler attached are just too expensive imo. I figured ill just get the cooler itself & then spend a whole weekend working on getting the valve & the cooler cleaned up.

    Also just found this & would like input as well please: https://ebay.us/m/z02L4w

    EGR valve is separate about 128 bux new. The cooler I'm not sure what new would cost usually tanked at machine shop makes it new again .

    Well now offense, but just the valve itself won't help if the cooler doesn't come with it. My understanding is that part of the issue with the 3rd Gen is the cooler attached to the valve. That's why I'm trying to find either the cooler or both parts together. Btw I just edited the original to include a possible used pair at a very reasonable price.

    What . Sir it all comes in pieces I've it sitting right here apart like a couple 10mm . Cooler gets tanked to clean like new EGR valve has a newer updated part . So it gets replaced for the cost I stated . This is all normal repair stuff for this model . No secrets . You can see you tube videos for weeks of watching for gen3 engine nonsense. I promise it's two pieces . You buy and EGR valve their won't be a cooler in sight of that box unless it's the one from you're engine.

    Hey there I think there was some miscommunication along the way. I've already watched videos on how to remove it. I'm fully aware that they can come apart. What I'm trying to figure out is if I should just get it all used or just focus on the cooler itself since the cooler is more difficult to find in general. No one wants to make new EGR coolers.

    EBay and salvage yard buys may be a valve/cooler combo.

    It's just a radiator for EGR gasses just gets tanked all the crap come out and flow HG is restored . The valve on other hand is a bit more complicated. They go in trash at salvage yard generally.

    Forgive the silly question but why not just clean the cooler and valve that are already in your car?
    Especially since you have to take them out in the first place????

    I've seen several videos where people have used oven cleaner to clean out the deposits and I have read posts from drive-by engineers and technicians that warn this will destroy the whole car.

    Me?
    I'd give it a go - especially since you're thinking of just replacing the parts anyway....... ;)
