It’s crucial to have gases reintroduced in to the consumption air so as to provide particular pollutants in the exhaust to levels required by the government, to meet certain emissions specifications. This dilutes the intake charge, proportionally decreasing NOx emissions created during the combustion cycle. A cooler is incorporated into the EGR system to deliver the temperature down to manageable amounts since you’d not need to shed hot exhaust gas into the in-take manifold directly. Once cooled, the EGR system re-introduces the exhaust gases back to the combustion chamber.
The cooler has motor coolant working through it, and over all the cooler looks much like a heater core or standard radiator. Exhaust gasses pass-through the cooler and are decreased to your temperature that can be launched back to the consumption system. On the 6.0L Strength Stroke engine, it’s an incredibly straightforward system which consists solely of a valve and a cooler. The exhaust gasses are let from the cooler when the engine’s computer selects the EGR valve to open under particular conditions and into the intake manifold. That is the first major failure point of the EGR cooler: even when it’s not in use, exhaust gasses are constantly milling about inside it.
The issue is heat. Both EGR cooler and EGR valve are prone to failure, and the offender that is common is soot build up. It often becomes clogged, causing the extreme warmth, when soot gets to develop in the EGR cooler. The EGR coolers have been known to neglect & leak coolant into the exhaust method (generally, white smoke is noticed coming from the exhaust). It leads to horrible running, which will be usually misdiagnosed as awful injectors, awful turbos, faulty FICMs, or a host of possible difficulties that can be expensive misdiagnose and invite unnecessary that is expensive repairs.
It’s not impossible for a completely stock engine to produce exhaust gas temperatures nicely in excess of 1000 degrees. And despite the cooler being made from materials meant for higher temperatures, it ca n’t be handled by it over too long a time – it’s not a matter of if the EGR cooler will fail, but when. The 6.0L Powerstroke exhaust-gas re circulation valve and cooler failures are a leading contributor to dependability concerns. 2003 model year PowerStrokes have a round EGR-cooler, which is somewhat less prone to failure compared to the square that is less efficient -cooler discovered on 2004-2007 model year engines, but the service time that is lengthier most of these trucks have seen make them far from immune to issues.
Beyond the main failtures, the 6.0L Powerstroke EGR valve and cooler are also a notorious source of issues due to coolant loss. To combat this host of problems, many producers of performance parts developed EGR delete kits. The EGR delete kits for the Ford 6.0 eliminate the EGR cooler and eliminate operation of the EGR system. Most mechanics will advocate deleting the EGR via a delete package once your 6.0L truck reaches 50,000 miles or more to avoid costly problems later. Advantages of installing a Ford 6.0 Powerstroke EGR delete package comprise increased hp, lower motor temperature, and improved horsepower. Many gearheads – particularly diesel truck proprietors – have found that by deleting their EGR they get instant performance increases.
It’s very important to remember the intention behind the EGR system would be to reduce emissions. If you are contemplating deleting the EGR systemin your truck, check in your state with the emissions and review regulations, unless your vehicle is employed just off-road. http://egrdeletekit.com
