Learn how to install a 6.7 Cummins EGR delete kit on a 2016 Dodge Ram 2500 with our comprehensive guide. Enhance your truck's performance with easy-to-follow steps and expert tips. Perfect for DIY enthusiasts and professional mechanics alike.
Introduction
An EGR delete kit can significantly enhance your engine's performance and fuel efficiency by reducing carbon build-up. In this guide, we will walk you through the steps to install a 6.7 Cummins EGR delete kit on a 2016 Dodge Ram 2500 using the Flo-Pro EGR delete kit. This guide will make the process straightforward and easy to follow, even if you're a beginner.
Preparation
Before starting, gather all necessary tools and materials:
- 8mm, 10mm, 11mm, and 15mm wrenches and nuts
- Penetrating oil spray
- Sealant
Ensure your vehicle is on a flat surface and the engine is cool to avoid burns or other injuries. Disconnect the battery to prevent any electrical issues.
Step 1: Removing the Engine Cover and Other Covers
First, remove the engine cover by unscrewing the 8mm bolts holding it in place. Next, take out the oil dipstick to give you more room to work. Place these components aside safely, as you will need to reinstall them later.
Step 2: Removing the EGR Pipe and Valve
Locate the V-band clamps on the EGR pipe and loosen them using an 11mm wrench. Carefully remove the EGR pipe. Then, unscrew the four 10mm bolts securing the EGR valve and remove it. Be sure to clean any gasket residue from the interfaces.
Step 3: Installing the Blocker Plate
Now, install the blocker plate from the Flo-Pro kit. Ensure the O-ring is correctly seated to prevent leaks. Tighten the new bolts securely.
Step 4: Removing the Intake Manifold
Disconnect the intake manifold by removing the 8mm bolts connecting it to the air filter and turbocharger. Also, detach the hose clamps using a 10mm wrench. Carefully remove the intake manifold and set it aside.
Step 5: Removing the EGR Cooler and Bracket
Spray penetrating oil on the bolts of the EGR cooler and let it sit for a few minutes. This will make them easier to remove. Unscrew the two 15mm nuts and the V-band clamp holding the cooler in place. Then, remove the four 10mm bolts securing the EGR cooler. Carefully lift the cooler out, keeping it at an angle to minimize coolant spillage.
Step 6: Installing the New Bracket and Coolant Pipe
Install the new bracket from the 6.7 Cummins EGR delete kit to support the transmission dipstick. If your truck has an Aisin transmission, this step may be unnecessary as the dipstick might be on the other side. Carefully bend any interfering components out of the way, being gentle to avoid damage.
Step 7: Reconnecting the Electrical and Intake System
Reconnect all sensors and electrical components. Reinstall the intake manifold, ensuring all connections are secure. Double-check all bolts and clamps to make sure everything is tight.
Step 8: Testing and Adjustments
Start the engine and check for any leaks or unusual noises. Pay special attention to the areas where you installed the blocker plate and reconnected the intake manifold. If you notice any hissing or whining, it may indicate a loose connection that needs tightening.
Conclusion
Installing a 6.7 Cummins EGR delete kit can significantly improve your truck's performance and longevity. By following this guide, you can complete the installation confidently and efficiently. Remember to perform regular checks and maintenance to keep your vehicle in top shape.
