Dana Corporation said it has developed a lightweight, robust cylinder-head-cover module for the Chrysler Group’s high-volume 3.7-litre V6 engine, which is used in the 2004 and 2005 Jeep Liberty SUV, Dodge Dakota and Dodge Ram light trucks, and the Dodge Durango full- size SUV.

Following on the success of Dana’s 4.7-litre module launched just over a year ago, the 3.7-litre module is comparable in structure and shares common components with the 4.7-litre. Manufactured from a hybridthermoset material, the Dana module weighs 4 pounds (1.8 kilograms) less per engine compared with the previously fitted system.


Improved noise, vibration, and harshness characteristics, as well as improved sealing performance, are achieved due to the application of an integrated press-in-place gasket along with a built-in grommet system. A specially formulated thermoset material also enhances function and durability by providing reliable long-term strength, even when exposed to extremes of heat and engine oil.


Dana provided in-depth product design, prototyping and validation support during the module development process, making it possible to launch the product in just nine months. The module is produced at Dana’s Paris, Tennessee, sealing facility using an advanced two-cavity straight injection moulding process.


“This new module eliminates a costly and time-consuming preparation and painting process, is more robust for shipping and handling, and reduces cost due to the press-in-place gasket over the previous plastic carrier-style gasket,” said a Dana spokesman.
