2007 Powerstroke

The 2007 PowerStroke trucks were the last models to use the 6.0 Liter engines.  These engines used in the 2007 PowerStroke trucks were much better than the 6.0 Liter engines used in the 2003 and 2004 model  years.  The 2007 PowerStroke trucks have had far fewer engine warranty claims than the 6.0 Liter Diesel engines used in 2003 and 2004 models.  The next model year after the 2007 Powerstroke started having a 6.4 Liter Diesel engine as an option, and Ford has since phased out the 6.0 Liter Diesel engine.  Ford is planning to move to a 6.7 Liter Diesel engine with the 2011 model year. There have been problems associated with all of these 6.0 Liter Diesel engines, including the 2007 PowerStroke trucks.

2007 Powerstroke Problem

One problem with the 2007 PowerStroke trucks is that there is a chirping or squealing noise when the truck is started.  This noise seems to come from a belt on the 2007 Powerstroke.  Currently the manufacturer suggests to check to make sure that the belts are neither frayed nor off-track.  If the belts are not frayed or off-track, then no repair is currently suggested.  Ford is still investigating this belt lssue with the 2007 Powerstroke.

2007 Powerstroke Engine Noise

Another problem with the 2007 PowerStroke trucks, as well as other models, is a clunking noise when the transmission is shifted into park from reverse gear or drive, from reverse gear to drive, or from 2nd to 3rd gear.  This is considered to be normal unless the issue occurs every time the transmission on the 2007 PowerStroke is shifted. 

2007 Powerstroke Engine Engine Power

A third problem with the 2007 PowerStroke is a lack of towing capacity and general power.  This can be due to a fuel filter that is clogged, a clogged pickup tube in the fuel tank, or clogged fuel lines.  Often these problems are the result of flaking or gradual delamination of the steel lining of the 2007 PowerStroke's fuel tank.  Replacement of the fuel tank will be necessary, as well as replacement of the the clogged parts.  Often these problems are the result of using biodiesel fuel of concentration greater than 5%.  Newer fuel tanks used for replacing the tanks in the 2007 Powerstroke have a laminated coating that is more capable of withstanding these flaking and delaminating problems.   The manufacturer's recommendation is still to use no more than a 5% concentration of biodiesel fuel in the 2007 Powerstroke.  

2007 Powerstroke Ford Leaking Oil

An additional issue or problem with the 2007 PowerStroke can be leaking oil from from the hot side intercooler hoses.  In the event that a hot side intercooler hose blows off it can cause the 2007 Power Stroke to lose power.  Hoses that are used for replacement have an inner liner that adheres better, thus fixing this issue.  The manufacturer does consider it acceptable to reuse undamaged hoses on the 2007 Powerstroke, but Ford does suggest that any hose that is reused be carefully inspected and thoroughly cleaned prior to reuse.  If the interior of the hose to be reused on the 2007 PowerStroke happens to be a bluish color the manufacturer recommends that a thin coating of silicone to the mounting surface after it is cleaned, and prior to being re-mounted.  This silicone coating on the hose for the 2007 Power Stroke should be allowed to cure for a minimum of three to four hours prior to starting the engine of the 2007 Powerstroke again.   The ideal boost pressure on the 2007 Powerstroke is between 22-25 PSI (pounds per square inch).  If it is higher, then the hose on the 2007 Power stroke may tend to blow off.

2007 Ford Powerstroke

If the cold side hose tends to blow off at the intake manifold, then the plastic tube should be replaced with the suggested part from the Ford dealer.  The intercooler and intake flange should both the cleaned with cleaner designed for brake parts.  the hose should be seated on the intake manifold and torqued to 9 foot/pounds.
