Jasper Engines & Transmissions, which makes remanufactured drivetrain products, has made updates to the Ford 6-liter diesel engine targeted to increase the longevity of the engine and customer satisfaction.


Prior to the 2004 model year, the Ford 6-liter used a 90-millimeter water pump impeller. "Starting in 2004, the impeller was increased to 100 millimeters and the front cover was also changed to provide a larger cavity for the water pump," says T.J. Abrams of the Jasper Quality Division. "Jasper automatically updates pre-2004 models to provide the later front cover, and the larger water pump impeller, to improve engine cooling."

Another Jasper update is to the water pump itself. "The factory water pump impeller is made from a composite material that can crack, cause engine overheating concerns and possible damage to the front cover rendering its replacement," says Abrams. "Jasper installs a pump with a steel impeller to eliminate this failure and provide long life for the pump."

Finally, many Ford 6-liter owners have experienced head gasket failures and would prefer an alternative to the typical head bolt. "In response to this demand, Jasper offers a Ford 6-liter that incorporates ARP head studs for increased rigidity and greater customer confidence," says Abrams.
