Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the EGR valve on this 2003 Mercury Mountaineer with the 4.6-liter V8 engine. It's the same part and similar process on the these Mountaineers from 2002 to 2003. The items that you'll need for this include a new EGR valve from 1AAuto.com, a 1 1/16" wrench, and 10mm and 11mm sockets, and a ratchet.
Start off by removing these two 11mm nuts. We'll just fast-forward as Mike does that. Lift the engine cover up and off. Then open up the clip on the back and pull the hose free.
Now your EGR valve is right here. You can just pull this hose off the top of it. It's held in with two 10mm bolts and then this large nut right here. You want to start off just using your 1 1/16" wrench to loosen up that nut. Then, after a couple turns with the wrench, it will loosen up enough where you can just loosen it the rest of the way by hand. We'll continue to fast-forward as Mike removes those two 10mm bolts. As you pull out that second bolt, your EGR valve will pull free.
On the left is the old EGR valve; on the right is the new one from 1A Auto. You can see they're identical and they'll fit exactly the same. Our old gasket came off right with the EGR valve, but if your gasket sticks to the intake manifold you'll need to remove any gasket material.
Start the bolts into the new gasket, and then start the bolts into the engine and tighten them up. Then line up that tube and twist that nut into place by hand. Once you get it in as far as you can by hand, just tighten it up with that wrench. Push this hose back into place, take your cover, and push it back down into place to make sure those clips push back in. Then replace those two 11mm nuts and tighten them up. Then push that hose back into the clip and close the clip.
