Valve Springs: Description
WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, and 2004 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
The valve springs are made from high strength, chrome-silicon steel (Figure). The springs are common for intake and exhaust applications. The valve spring seat is integral with the valve stem seal, which incorporates a garter spring to maintain consistent lubrication control to the valve stem.
