The 6.0L had some significant issues early on in its production run but by 2006 some of these issues had been resolved. This may have been too little, too late for some who had purchased this new platform expecting it to give the same outstanding service they had received from previous models. Ford and Navistar would like to put this chapter behind them, but there are literally thousands of these trucks on the road.

 

Having worked for several years on the previous Powerstroke, and myself being a firm believer in the durability of the 7.3, I was somewhat sympathetic to this manufacturer. that was until I saw the band aids applied and  the multiple failures over and over. for instance, the many times I have seen an EGR cooler failure which lead to head gasket failure, go in for warranty repair, only to fail again causing yet another warranty repair with the same parts that had failed in the first place, although some had been re-designed. None of the warranty repairs have addressed the root cause of failure. The entire cooling system must be considered when related components have failed.

 

At the forefront of this fiasco was a rush to get this platform in service to satisfy the demanding expectations of you, the power stroke owner, while adhering to stricter EPA emissions standards. This had negative consequences for both Ford Motor Company and Navistar in the form of lawsuits and lost customer confidence.

 

If you operate a 6.0L, it is important you use only Motorcraft filters. Ford has a patent on these filters and they are specifically designed for your 6.0L. Motorcraft's Filter Comparison slideshow shows key differences and quality concerns between OE and aftermarket filters. The proper filters will offer better protection, not to mention if you expect warranty repairs of injector issues, and you have aftermarket fuel filters installed, your claim may be denied. So protect your warranty, use only Motorcraft filters in your 6.0L.

 

The most common failure we’ve all heard about or experienced are the fuel injectors, I know of one truck that has has twenty three injectors now. The main problem with these injectors was a sticking spool valve. Ford and Navistar engineers invented a new word to describe this condition, Sticktion. the solution to the problem was a re-flash to the FICM, fuel injection control module, called an inductive heating flash. later re-flash's also eliminated the pilot injection, this solved the hot start issue. How they were able to do this and still retain emissions standards is a true mystery. As usual this took about two and a half years into the production run to materialize while back in the real world, the problem has more to do with a lack of maintenance, poor oil quality, use of sub-standard filters, and dirty fuel. These injectors are made by Siemens. they were designed to run on fuel of high quality such as found in the European market where they actually have standards for lubricity and quality. by now, most of the early design injectors have been replaced and with proper service intervals, injector failures should be minimal.

 

Dirty fuel will kill these injectors. Dirty oil will kill these injectors. Running your 6.0L power stroke out of fuel will kill these injectors. The later 6.0L had a program which limited fuel pressure under low fuel conditions, but you should avoid running out of fuel at all cost. The fuel inside the injector provides a cushion for the internal valving. Anything that would cause low fuel pressure, such as a clogged filter or weak pump, can destroy these injectors. If your 6.0L PSD has any symptoms such as hard starting when cold, excessive smoke, misfire, stalling, rough running, buck/jerk, or low power, get it in for repair right away as even a minor issue can quickly develop into a catastrophic engine failure.

The biggest common failure is the EGR cooler. Most cooler failures can be attributed to a lack of coolant flow from the engine oil cooler. It has been directly linked to head gasket failure. The EGR cooler will develop a leak causing a loss of engine coolant out the exhaust and into the intake when the EGR is opened. In many cases, through a horrible series of events, this will lead to a catastrophic engine failure due to overheating, or coolant entering the combustion chambers. If you have such an issue or plan to power up your 6.0L, insist on having the cylinder head bolts replaced with studs. The EGR valve and passages are also prone to carbon build up. We now carry an aftermarket EGR cooler and engine oil cooler. These units are far more robust and durable than the stock units.

 

This platform has a very specific coolant requirement. The coolant used in your 6.0L PSD has been specified by Ford and Navistar to ensure the longevity of cooling system components. This coolant is ethylene glycol based. It is significantly different than other ethylene glycol based coolants. It is whats called an HOAT/G05. Do not put Dex-Cool in your 6.0L PSD. Using only the recommended coolant will prolong the life of your cooling system, and when combined with proper maintenance of the entire vehicle, add to the longevity of your truck.  We cannot stress this enough, do not under any circumstances mix any other type of coolant in this cooling system.

Many people neglect the cooling system on their truck, it should be tested at least yearly for PH and freeze/boiling point. there is an additive available from Ford that should be used in the 6.0 liter diesel. due to oil cooler problems,  I strongly recommend the installation of a coolant filter system to trap casting sand, iron shavings, and silicate crystals formed from cooling system neglect. We have a coolant filtration system that can be purchased from us, or even installed here at Fleet Service Northwest.

 

The next item of issue was the variable geometry turbocharger or VGT. This is the heart of the performance of a 6.0 liter. it provides a relativly quick spool up, thus providing an off the line acceleration that can be considered astounding for a seven thousand pound Truck. And if you drive a 6.0, you've experienced this first hand. This turbocharger is the heart of the outstanding performance of a stock 6.0 liter powerstroke diesel.

 

There are other manufacturers of Diesel platforms in the light/heavy duty market who use the same VGT technology without soot buildup issues, These issues on the Ford can be attributed to fuel strategy which has only been compounded by the FICM reflash which has resulted in more soot emissions for certain. excessive exhaust gas temperatures can and have also destroyed these turbochargers. The 6.0 liter turbocharger is prone to carbon buildup which will cause the moving parts inside to seize and cease to operate correctly. In extreme cases this would cause a failure of the hydraulic/electronic solenoid that controls the function of the turbocharger. Poor fuel quality has attributed to this, but with the advent of Ultra-Low Sulfur Diesel, this condition might well improve, I am skeptical due to the poor quality of our nations #2 diesel fuel supply.

 

 Hard acceleration of this platform every now and again will help reduce this condition by not only operating the VGT through its entire range, but also through creating higher exhaust gas temperatures than you would get under normal driving conditions. Use of high quality diesel fuel additives which lubricate and increase Cetane as well at regular intervals such as when performing preventive maintenance, is recommended.

 

 If you wish to power up your 6.0 liter powerstroke diesel, I will offer you this advice. a high percentage of failed head gaskets we've repaired have had aftermarket tuners installed.

 

 

As you can see, the 6.0 liter Powerstroke diesel has some problems, but the staff  at Fleet Service Northwest are here to help you not only repair these problems, but to assess them and find the solutions to minimize a repeat failure. We have the equipment, information and knowledge to accurately diagnose and repair the 6.0 liter Powerstroke diesel. We have seen many head gasket related failures lately. in all cases these trucks were stock, with the exception of one that had an aftermarket intake filter and exhaust system. We have seen other trucks go over 150k without a head gasket issue as well.

Remember a day in America when the local auto parts store, hardware store, and other local businesses sold products they believed in, and the person at the counter recommended products not by reading a computer screen telling them what to sell, and not based on the commission they make, but on their expertise and experience? People whose desire to run a profitable business came after the love of their Country, and their desire to do what is right? If not, do you at least remember your dad or grandpa talking about such a day? A day before the big chain stores sold rows and rows of Chinese products that the manager and sales people know nothing about? Its been said that those days are gone, never to return, but these are exactly the principles that we have founded our business on, and we aim to do our part in restoring the America that we all long to live in. read more
