Section 1 (3.7L Engine (Service Information)): Springs-Valve: Notes

WARNING: This page is about a different variant/trim than selected.

The valve springs are made from high strength chrome silicon steel. The springs are NOT common for intake and exhaust applications. The valve spring seat is integral with the valve stem seal, which is a positive type seal to control lubrication.
