Here are some step by step instructions on how to install your 6.4 Powerstroke EGR delete.

1. Make sure the front wheels are straight.
2. Disconnect both batteries.
3. Drain the coolant using the coolant drain plug located on the bottom of the radiator on the driver side.
4. Remove the 3/8” hose that runs to the degas bottle. *Save this hose, as you will need it later on.*
5. Remove the upper radiator hose by popping the wire clip out and pulling the hose straight out.
6. Remove the driver side battery and battery tray by removing the four bolts. The degas bottle is attached to the battery tray so be sure to disconnect all coolant lines going to the degas bottle as well as the vacuum line running to the battery tray.
7. Disconnect the electrical connector at the top of the vertical cooler followed by the band clamps that hold it in place, as well as the nut and bolt that hold the top of the cooler.
8. Loosen the clamp on the intercooler tube and pull the tube out of the boot. *It is not necessary to remove the entire intercooler tube.*
9. Disconnect the two coolers from each other by removing the two nuts on the back of the flange and prying the two flanges apart.
10. Hold the intercooler tube back while pulling the cooler up and out. You may need to try rotating the cooler to get it out of the mount.
11. Remove the plastic coolant “Y”. It is brittle so be careful when removing it.
12. Remove the upper radiator hose from the thermostat housing. *If the upper radiator hose is the old version with the single o-ring, you should replace it with the new double o-ring version.* The older version is all black, where as the new version has a whit e end that goes to the thermostat housing.
13. Remove the upper EGR cooler mount. There are three head bolts, and one head stud. *Be sure to keep the stud, as you will need it later on to secure the power steering line.*
14. Remove the nut that secures the dipstick tube in place. Do not discard nut.
15. Remove the steering shaft bolt and slide the stem up and off of the steering box side. Be sure not to turn the steering wheel or tires.
16. Loosen and remove the nuts on the band clamps that hold the lower egr cooler in place. In some cases it may be easier to get them through the wheel well.
17. Remove the rear cooler hose. It may be easier to cut this hose.
18. Remove the two bolts from the rear of the cooler; it is easiest to remove the top bolt from above and the bottom bolt from underneath the truck.
19. Rotate the cooler and pull it forwards to remove it from the bracket. You will need to move the dipstick out of the way to do so.
20. At the front of the coolant line that is attached to the cooler bracket, remove the bolt that holds the coolant tube to the timing cover. *The tube and the cooler bracket will come off in one piece.*
21. Remove the four bolts from the lower cooler bracket.
22. Install the four new exhaust manifold bolts and torque to factory specs.
23. Install the exhaust block off plate using the 2 new bolts and nuts and exhaust gasket
24. Re-install the dipstick hold down nut.
25. Remove the upper cooler hose and steel tube that was attached to the top of the upper cooler and discard.
26. Install the coolant plugs using the factory hardware in place of the lines that came from the cooler.
27. Re-install the stud that was saved from step 12 with the standoff that has been provided then re-install the power steering line support bracket.
28. Re-install the plastic “Y” being careful not to break it.
29. Reconnect the steering shaft and torque to factory specs.
30. Re-install the battery box. Remember to hook up both coolant lines and the small vacuum line.
31. Clean the end of the silicone boot and intercooler tube and re-install.
32. Re-install the upper radiator hose making sure that the metal clips are securely in place.
33. Install the egr block off plate where the top of the upper cooler was attached. *We have supplied two bolts for this plate so that the stud can be remover if you choose to do so.*
34. Use the 3/8” hose that was saved from step 4 to make a piece to reconnect the coolant line to degas bottle and splice it together using the supplied nipple and the existing hose clamps. Use the black routing clips to hold the line in place.
35. Re-route the loose coolant hose on top of the engine back around open coolant port next to the egr block off plate using the factory hose clamps.
36. Fill the truck up with the correct coolant and run the truck checking for leaks. Once the truck reaches operating temperature, top off the coolant.

Pros and Cons of an EGR Delete Kits

Deleting the EGR on a diesel engine creates several pros and cons.

Pros

• Elimination of harmful contaminates being reintroduced back into the engine.
• Warm exhaust gases being sent away from the engine through the vehicles exhaust system.
• Increase in the Diesel mpg. Some people experience gains of almost 5 mpg making this a very fuel efficient modification.
• Engine coolant will not be as warm because it doesn’t have to cool the exhaust like it did when the EGR was still on the vehicle.
• Increase in the longevity of the engine because it will be running cleaner and more efficiently.
• Depending on the truck one has you can experience faster turbo spool up.
• Coolant will flow faster through the engine because it will not be diverted by the EGR cooler.
• Less likely to have a blown head gasket.
• Examples of Custom Diesel EGR Delete Kits

  • Dodge- http://www.custom-diesel.com/egr-delete-kits/dodge-egr-delete-kits/6-7-cummins

Cons

• Increase in EGT because the non oxygen containing exhaust is not being readmitted back into the cylinder to keep EGT’s low.
• Some of the cons would be created by the oil cooler on the 6.0 Powerstroke but they can be prevented by regular maintenance. Other Diesel engines may differ depending on design and year model.
  • Flush coolant
  • Change coolant filter
  • Some people install new oil coolers during EGR deletes to decrease chances of having a faulty cooler creating a leak and more down time because of engine repair.

As you can see the EGR delete definitely has more pros than cons. Custom Diesel makes EGR delete kits for your performance diesel truck to handle whatever you do whether it’s driving on the street or racing the ¼ mile. Order your EGR from www.custom-diesel.com

6.0 Powerstroke Diesel Performance

Do you own or are you considering the purchase of a 6.0 Powerstroke? If so Custom Diesel is the place to buy all the performance parts you need. As most people know the 6.0 Powerstroke has been plagued by problems from the factory however with a few modifications one can have quite possibly the most reliable truck on the road. These engines have been known for problems with their head gaskets because of overheating mainly because of the EGR system. Like most diesel owners we all want a little more power than we receive from the stock computer tunes this is where Custom Diesel can help for your 6.0 diesel solutions.

The first thing we recommend is the purchase of our Custom Diesel EGR delete. This delete package is one of the most critical parts to giving your 6.0 Powerstroke that lasting performance we all want from our diesel engines. The EGR system cools exhaust gases as it sends them back into the engine to reduce emissions. When the exhaust is sent back into the intake it gets clogged up with soot and other harmful diesel particulates. By installing this delete kit you will do many things to help your engine. Engine coolant will be cooler preventing the possibility of blowing a head gasket resulting in costly repairs. You will receive better fuel economy. Some customers have experienced gains of almost 5 mpg. The up pipe we manufacture can also increase turbo spool up resulting in quicker boost.

Next on the list would be the install of ARP head studs. If you want to have the added power from a tuner head studs are a must. With the added power from a tuner the factory head bolts can become stretched and result in a blown head gasket with high performance tunes. Head studs can handle large amounts of power that can be made with the 6.0 engine. If you are going to do a head stud install it is best to lift the cab so you will have more room to work with. We also offer head gaskets in some of our solution kits.

Now that we have the cooling and head gasket issue solved it is time to add the high performance parts. In order to get the most from a tuner your truck must breathe well and that means the addition of an exhaust and intake. At Custom Diesel you can order single or dual performance exhausts. It’s just personal preference from there. Factory air intake boxes are good for almost 500 horses in some cases but if you seek more horsepower than that I’d recommend an aftermarket intake. We offer several different tuner options like the SCT SF3 programmer. It has three preloaded tunes with power levels capable of up to 150 additional horsepower and even economy tunes of 75 horsepower. This tuner has the ability to upload custom tunes from the internet also.

Other performance options would be the addition of an aftermarket turbo as opposed to the stock turbo. One we offer is the Industrial Injection Garret Power Max Stage One. This Turbo will help increase spool up by maximize power output but keeping turbo speeds down for the same output. This turbo can support up to an additional 175 horsepower over stock and would be a good replacement for a stock one also. All of these products are available on our website and are ready for purchase at anytime. This setup has been proven over time to be reliable and make nice amounts of power also.
