Why you should upgrade your 6.7 Cummins to a performance version

6.7 L Cummins Radiator Upgrade

If you are the proud owner of a 6.7 Cummins powered truck, then you know that this engine is a workhorse. But even the best engines can benefit from an upgrade, and that is especially true when it comes to the 6.7 Cummins.

One of the most important upgrades you can make to your 6.7 Cummins is to install a performance radiator. A performance radiator will help keep your engine running cooler, meaning that it will be able to handle more power without overheating. This is essential for anyone who wants to take their truck to the next level and really push its performance limits.

Whether you have a stock performance version, a modified version, or a fully dressed out rig, it is always a good idea to keep an eye on your Cummins engine temperatures. Keeping the truck cool will not only help to extend the life of the engine but also prevent costly repairs from being needed prematurely. A well performing radiator should be your first step in cooling down those hot temps. Replacing the factory radiator with one that has been built customized for your rig is just as important as swapping out the glow plugs and updating any other components to ensure they are running at their best. The same goes for adding an auxiliary cooler – putting an extra radiator in line will lead to even lower operating temps can save fuel and make for a more dependable Cummins engine.

If you are in search for the best upgrade in terms of cooling, the answer will vary depending on your truck’s capabilities and how you use it. Some options may be better than others if you spend most of your time with an empty trailer behind you where there would be less air flow to cool down or if you need something that can manage high loads when pulling up steep grades. No matter what your needs are, we have compiled information about some great choices below so that when it comes time to purchase a new radiator, you know exactly which one is right for you!

How to Install 6.7 Cummins Radiator

6.7 L Cummins Radiator Upgrade

Upgrading your radiator is a great way to improve your truck’s performance and longevity. When it comes to choosing a radiator for your 6.7 Cummins, there are a few things to consider.

The first thing to think about is the size of the radiator. Make sure that you choose a radiator that is the correct size for your truck. You’ll also need to make sure that the inlet and outlet sizes match up with your existing plumbing.

The second thing to consider is the type of radiator. There are two main types of radiators – tube and fin style, and plate style. Tube and fin style radiators are more common, and they tend to be less expensive than plate style radiators. Plate style radiators are more efficient, but they are also more expensive.

The third thing to consider is the brand of radiator. There are a number of different brands available, and each brand has its own strengths and weaknesses. Make sure to research different brands before making a decision.

What you’ll need: New Radiator.

  • Tool box
  • Socket set
  • Wrenches
  • Pliers
  • Allen keys
  • Flat head screwdriver
  • Hammer
  • Pry bar
  • Foil Tape

Step 1: Bumper removal

Front bumper on Ram Cummins diesel trucks are held on with 10 bolts. Remove these bolts using a socket set, and then set the bumper aside. Some of the bolts may be hidden behind plastic trim or other accessories, so be sure to remove everything in order to get to all 10 bolts.

Step 2: Headlight removal

The headlights are held in place with two screws on each side. Use a socket set to remove these screws, and then pull the headlight assembly away from the truck. There are wires attached, so be sure not to rip any wires out.

Step 3: Air intake box

The air intake box is attached with 4 bolts, two on each side. These bolts are accessible from behind the headlight area, making it much easier to remove them with a socket set than if they were located somewhere else. Now that all of the necessary components are removed, it’s time to pull up the radiator itself.

Step 4: Radiator hoses

On the 6.7 Cummins diesel engines, there are two hoses which connect directly to the radiator. One hose is for coolant, and one is for vacuum. Remove both hoses using a wrench or socket set on either end of each hose connection point (one location is on top of the radiator, and one is on the side).

Step 5: Radiator mounts

There are four bolts which attach the radiator to the truck. Two bolts are located at the top on each side, and two are located at the bottom on each side. Remove these bolts using a socket set, and then pull the radiator out from underneath.

Step 6: New radiator installation

Install the new radiator by reversing the steps above. Be sure to use all new hardware that comes with the new cooler. Also, be sure to tighten all bolts securely in order to prevent any leaks. Finally, reattach both hoses using a wrench or socket set on either end of each hose connection point (one location is on top of the radiator, and one is on the side), and then reattach the two radiator mounts using a socket set.

Step 7: Reinstall headlights

Replace the headlights by attaching them to the truck with a socket set and screws. Finally, reattach all of the accessories such as front bumper, horns, and headlight assembly (be sure not to bump any of these back into place). Now that everything is reinstalled, it’s time to add some coolant. Be sure to check your owner’s manual for specifications on what type of coolant to use in your engine.

Step 8: Add coolant

Open up both radiator caps in order to let air escape from each side where they connect together. Afterward, pour in 4 gallons of coolant into the radiator, making sure to add it slowly. Replace both radiator caps, and start up your truck. Let the engine run for a few minutes in order to allow the coolant to circulate throughout the system. Finally, check the coolant level and add more as needed.

When upgrading your radiator on your 6.7 Cummins diesel engine, it is important to use a high-quality aftermarket cooler that is specifically designed for your truck application. This will help ensure maximum cooling efficiency and optimal heat transfer, which can be crucial for heavy-duty diesel applications. By following this tutorial, you can install a new upgraded custom-fit aluminum radiator in just a few simple steps. Be sure to have a tool box handy with all of the necessary sockets and wrenches, as well as a few gallons of coolant.
