Bullett Proof- Episode Two - EGR Coolers

Bullet Proof Diesel is known for its many solutions to Ford diesel issues. In these next few blogs we will be discussing the top five different components they have to fixing these issues. As to not overwhelm you with a lengthy article we’ll take it part by part.

The EGR cooler is a component used to lower the temperature of the exhaust gases that are recirculated by the EGR system. The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and emit no emissions. There are a couple main signs that you might have a bad EGR cooler. First, you will notice a significant loss of coolant through your overflow bottle and/or cooling system. This can happen when the cooler is allowing coolant to leak back into the exhaust system and not outside of the engine like it should. Second, the white smoke out your tailpipe can be a sign of a bad or leaking EGR cooler. The white smoke is actually steamed coolant that has leaked and been vaporized.

There are a couple different options to fixing these issues. First, you can simply replace the EGR cooler with another Ford factory piece. However, the option we support here at Dana Brothers is to Bullet Proof your vehicle. To most this brand may be unfamiliar. Known nationally for their work on Ford vehicles, Bullet Proof Diesel is based out of Mesa, Arizona. They have created alternate and better solutions to the many Ford issues that occur in diesels over their life spans. One of these being the EGR cooler. They have designed a cooler with stainless steel tubing to resist fatigue and heat failures, all joints are TIG welded, and they have numerous quality control procedures to guarantee a seamless fit back into the truck.

It is important to fix these issues sooner rather than later because the following issues can occur if not taken care of properly: the head bolts will stretch, the head gasket might blow, the engine can overheat, or you might even incur turbo issues. There are so many outcomes based off the extremity of the EGR cooler’s condition so make sure to bring it in and have it diagnosed.
