What is 6.0 Powerstroke Engine?

Since 1994, the Powerstroke was an engine family that has been a re-branding of Navistar International’s Medium-Duty truck engines, which were renamed Powerstroke 7.3.

Later, the 7.3-liter Powerstroke engines were phased out in favor of the 6.0-liter (365-cubic-inch) engines in late 2003. In the Ford Super Duty trucks, the 6.0L Powerstroke was utilized until the 2007 model year.

But remained until 2009 inside the line of Ford vans call (Ford Econoline vans), (2010 model year), and also inside the Ford Excursion SUVs till after 2005 versions when Ford ended Excursion manufacture.

However, the engine’s bore and stroke measure 3.74 inches by 4.13 inches by 105 millimeters, resulting in a dimension of 5,954 cubic centimeters (6.0 L; 363.3 cu in).

With an 18.0:1 compression ratio, it produces 325 horsepower (242 kW) and 570 lb-ft (773 N-m) of power with a turbocharger called (variable-geometry), and intercooler.

What is 6.0 Powerstroke Engine Coolant System?

There are a plethora of chemical combinations and formulations for engine coolant/antifreeze.

All 6.0L Powerstrokes were supplied with the Motorcraft Gold type of engine coolant when they were manufactured.

The silicates found in Motorcraft Gold are made up of oxygen and silicon atoms.

Thermal breakdown occurs, and silicates are driven out of suspension, resulting in the formation of clogs in the oil cooler, as a result of this process.

The 6.0 Powerstroke best coolant of Ford’s Motorcraft Gold engines has been recognized as a plausible (likely) cause of oil cooler clogging in the 6.0L Power Stroke.

Which year and model of ford engine have 6.0 powerstroke coolant system

In the 2nd quarter of the model year 2003, the 6.0 L took over. In the Ford Super Duty trucks, the 6.0L Powerstroke was utilized until the 2007 model year, but remained inside the Ford Econoline vans until 2009 (2010 model year) and inside Ford Excursion SUV line until after the 2005 versions when Ford ended Excursion manufacture.

How often should you change the coolant in a 6.0 Powerstroke?

What kind of coolant you choose and how you drive your truck will have an impact on this one? After three years and 25,000 to 30,000 miles, any type of coolant is still good to go.

An HD coolant of high quality will last for five to six years, or around 150,000 kilometers. A little more time in a nice ELC.

Just follow the instructions in your owner’s handbook if you don’t know anything about coolants.

It may say “every three years” or “every 25,000 or 30,000 miles”, depending on the model. If you don’t recall the last time it was changed, I’d suggest you do so immediately.

Here’s how –

WARNING: Never open the cooling system without first letting the engine cool completely. Attempting to remove the coolant pressure-relieving valve while the engine is running, or when the cooling system gets hot, is dangerous. Hot liquid can be ejected with force if the cap on the cooling system gets unfastened even little. This could result in significant injury if you don’t follow these directions.

Before changing the coolant, Ford suggests that you apply VC-9, an iron-removing flush chemical.

  • Disconnect the pressure-relieving valve or cap once the pressure has dissipated
  • Disconnect the power to the cooling system and turn it off. This section’s Cooling System Draining, Filling, and Bleeding section has more information
  • ACL (Air Cleaner) component can be removed. Section 303-12 contains more information
  • Remove the electrical connectors for the Mass Air Flow (MAF) sensor and the air filter minder
  • Take off the back ACL cover by loosening the clamp
  • Remove the thermostat casing from the upper radiator hose
  • Remove the thermostat housing and the bolts
  • Using a vise, hold on to the thermostat assembly. Remove the thermostat by pressing downward on the crossbar of the thermostat and rotating it out of the thermostat housing
  • The old O-ring seal should be used during the flushing process
  • Put together the housing assembly of the thermostat but leave the thermostat out of the mix. Assemble the screws.
  • Use 23 Nm of torque (17 lb-ft)
  • The housing assembly of the thermostat should be connected to the top radiator hose
  • Assemble and fasten the rear ACL cover
  • Connect the electrical connectors for the air filter monitor and the MAF
  • Activate the Access Control List element. Section 303-12 contains more information
  • Not at this time is the Drain Plug in the RH Cylinder Block
  • The drain plug of the LH cylinder block should be removed, and the cylinder block should then be drained
  • Clean engine oil should be lightly rubbed into the seal of the O-ring, which is found on the block drain plug, before installation
  • Drain the LH cylinder block by unscrewing the drain plug
  • Allow 20 Nm of tightening (177 lb-in)
  • Use the Engine Cooling System Iron Cleaner from Motorcraft® for auxiliary climate control or commercial cars with auxiliary heaters 2.83L (3 qt) (VC-9)

Common Problems of 6.0 Powerstoke Engine

01. FICM Failure

There has been a history of problems with the Powerstroke engine’s Fuel Injector Control Module (FICM). The solenoid voltage is supplied by the FICM.

Two solenoids supplied with electricity from the FICM govern how much oil enters the fuel injectors. The FICM is also affected by engine heat and vibration, leading it to overheat and fail.

02. EGR Valve Failure

The 6.0L Powerstroke engine has been known to have issues with the EGR valve. This valve controls the amount of exhaust gas that is recirculated into the engine.

The EGR valve can be clogged by soot from the exhaust, resulting in its failure.

Your Superduty truck’s engine performance will suffer if the EGR valve becomes stuck open as a result of using subpar diesel fuel.

03. Head Gasket Failure

The TTY head studs or torque-to-yield are the crux of the Powerstroke’s head gasket problem.

Because of aftermarket modifications, many Ford Superduty operators have discovered that the TTY head bolts are not capable of handling the increased pressure under their head gaskets.

A blown head gasket is the result of faulty TTY head studs.

04. Oil Cooler Problem

The 6.0L Powerstroke gasoline engine’s oil cooler can also be a source of concern.

Ford installed a liquid-on-liquid oil cooler in the 6.0L diesel engine since the Powerstroke engine requires more cooling than other diesel engines.

The oil cooler becomes clogged with dirt and debris, and as a result, the EGR cooler begins to fail.

05. EGR Cooler Failure

The EGR cooler of your Ford Super-Duty engine might potentially fail due to clogging, in addition to the failure of the oil cooler detailed previously.

This increases the EGR cooler’s temperature, which eventually causes failure to your head gasket as well.

A white exhaust will come out of your Ford’s tailpipe if your EGR coolers leak coolant into the exhaust system.
