Every time you fire up your 2015 RAM 1500 3.0 EcoDiesel, the hum of the engine is like a promise—an invitation to get things done, whether it’s hauling heavy loads or cruising the open road. But sometimes, that promise falters. Maybe the engine stutters, or the Check Engine light flickers, reminding you that something’s wrong. Often, it’s the EGR valve, a small but mighty part of your emissions system, quietly fighting to keep things running smoothly. But when it fails, it can start to feel like everything’s just a little... off. Carbon buildup? Performance loss? Not anymore.
If you’ve got the tools, the patience, and the will to dive in, replacing that old, worn-out EGR valve can turn your engine back into the purring powerhouse it once was. Ready to take on the challenge? Let’s go.

Step 1: The Calm Before the Storm—Preparation
Like any journey, it’s important to check your map first. Before diving into the thick of things, make sure you have everything you need. This isn’t a race. Take your time.
- Check your parts. It’s always a good idea to ensure everything's there before starting. Trust me, you don’t want to be halfway through the job only to realize you’re missing a crucial bolt.
- Disconnect the battery. You wouldn’t want a spark at the wrong moment, right? Disconnecting the battery is the safest first step, ensuring your hands stay free of unwanted shocks.
Step 2: The First Step—Removing the Injector Cover
With the tools in hand and the truck parked, it’s time to make your first move. The injector cover might seem like a small part of the whole, but it's the doorway to the deeper layers.
- Pull gently, but firmly, on each side of the injector cover, dislodging the locating pins. Feel the resistance, and then the release as you free it from the engine. There’s something satisfying about this first step, the weight of the cover in your hands, knowing that it’s one less barrier between you and the heart of your EcoDiesel.
Step 3: Exposing the Hidden—Removing the Foam Pads
There it is. Beneath the injector cover lies the hidden world—the EGR tube, the unsung hero in your engine. But before we can get to work, there’s something in the way: the sound-absorbing foam pads.
- Gently peel them away, exposing the EGR tube, wrapped in protective heat insulation. You’re closer now, feeling the promise of a job well done just within reach.
Step 4: The Path to Freedom—Loosening the Intake Tube
Now the real work begins. The intake tube is blocking your path. Time to loosen the clamp and start the slow but steady removal.
- Loosen the clamp on the flexible rubber hose, right where it meets the air intake tube.
- Pull the hose away from the filter box.
- Lift the intake tube carefully, but with purpose, freeing it from the ball-and-socket joint that holds it in place. With this, you’re now ready to access the EGR tube.
Step 5: Detach the EGR Tube—The First Bolts
You can feel the end of the road ahead. Just a few more bolts stand in your way.
- With your trusty socket wrench, remove the two 10mm bolts securing the EGR tube to the cooler side. Keep these bolts close; they’ll be part of your journey back.
Step 6: Freedom on the Other Side—Removing the EGR Tube
With the cooler side freed, it’s time to tackle the intake manifold side. This is where your precision counts.
- Using your 8mm socket, remove the two 8mm bolts. With these out, you can lift the EGR tube off the cooler side and slide it out toward the passenger side. It's a small victory, but the moment you feel the tube give way, it feels big.
Step 7: Installing the Blocker Plate—Sealing the Future
And now, the part where you lay the foundation for what's to come.
- Using the provided 10mm bolts (Part #H), install the blocker plate (Part #G) onto the valve cover port. This is the beginning of a new chapter for your EcoDiesel.
Step 8: Gaskets and Plates—Securing the Block
As you’re installing the cooler-side blocker plate (Part #E), make sure the gasket stays in place. The gaskets are subtle, but they’re vital, keeping everything sealed tight.
- Reinstall the gasket, then tighten the 10mm bolts from the factory kit to secure the plate. There's something comforting about the click of the wrench when everything locks into place.
Step 9: Putting It All Back Together—Intake Tube Reinstallation
The hard part’s behind you now. It’s time to begin reassembly.
- Reposition the intake tube, reconnect the ball-and-socket joint, and gently lower the tube back into place.
- Secure the intake tube back to the filter box, making sure everything clicks back together like a well-oiled machine.
Step 10: Reinstalling the Cover—A Job Well Done
You’ve come this far. Reinstall the foam pads and the injector cover, and just like that, you’ve turned back the clock on your EcoDiesel.
- Carefully place the foam and plastic engine cover back in place. The truck is beginning to feel like itself again. Take a step back and admire the quiet satisfaction of a job done well.
EGR Delete Kit: The Road Less Traveled—For the Brave and Bold
If you’re in it for more than just a replacement, if you’re looking to unlock true performance potential, then the EGR delete kit might be your next step. This road requires careful thought, but it promises better performance and improved engine efficiency.
The install will require a bit more elbow grease—removing the air filter box, disconnecting vacuum lines, draining coolant, and handling coolant pipes with care—but the end result is a truck that’s more responsive, more efficient, and more yours.
End of the Road? Not Quite—The Final Checks
Before you call it a day, take a moment to double-check your work. No road trip is complete without a final inspection.
- Tighten any bolts that might have loosened. Ensure your clamps are secure.
- Start the engine, listen for that steady hum, and check for coolant leaks. Your journey isn’t over until you’re sure the engine is humming in perfect harmony.
The Final Word: You and Your RAM 1500 3.0 EcoDiesel
There’s a quiet pride in working with your hands, in knowing that you’ve brought life back to your 2015 RAM 1500 3.0 EcoDiesel. Every wrench turn, every bolt tightened, is a testament to your commitment to your vehicle, your adventures, and the road ahead.
So go ahead—fire up the engine. Feel that power surge beneath your fingertips. The road is waiting, and so are the miles of memories yet to be made.
